- Hawk-Eye and Statcast: MLB uses an array of Hawk-Eye high-speed cameras in all 30 ballparks to power Statcast, tracking every pitch’s speed and trajectory along with player movement and even bat swings hawkeyeinnovations.com. This optical tracking system (introduced league-wide in 2019) feeds real-time data for analytics and broadcasts, and also underpins MLB’s replay review since 2014 hawkeyeinnovations.com. It enables new metrics (e.g. exit velocity, launch angle, fielder sprint speed, and soon swing attack angles) that deepen understanding of on-field performance.
- Automated Strike Zone (ABS): MLB is testing “robo-ump” technology via an Automated Ball-Strike System. In 2025 spring training, over half the games let teams challenge human ball/strike calls – with each club getting two challenges that are retained if successful reuters.com foxsports.com. When a batter, pitcher, or catcher signals a challenge, Hawk-Eye tracks the pitch and displays a 3D strike-zone replay on stadium screens in seconds reuters.com. Early results show about 51–52% of challenged calls were overturned foxsports.com. Umpires remain on the field, but this tech-driven challenge system (powered by T-Mobile’s 5G network) is a major step toward consistent strike zones, and MLB even plans to use it in the 2025 All-Star Game foxsports.com foxsports.com.
- PitchCom Communication: Traditional catcher hand signals are largely gone. Since 2022, all teams have adopted PitchCom, a wireless system where catchers (and now pitchers) press a keypad to call pitches, transmitting encrypted audio to earpieces worn by the pitcher and up to four fielders mlb.com mlb.com. This speeds up the game and prevents sign-stealing (a hot-button issue since the 2017 Astros scandal) pitchcom.com. In 2023 MLB even allowed pitchers like Zack Greinke to wear the transmitter on their belt or glove, letting them call their own game to beat the new pitch clock mlb.com mlb.com. As one veteran put it, “I throw a lot of pitches and just won’t be able to throw the pitch I want…if I can’t use that [PitchCom]” mlb.com – underscoring how this tech helps both strategy and pace of play.
- Wearable Player Sensors: MLB is ahead of some leagues in embracing wearables during play. It has approved at least four health and performance devices for in-game use: the Motus pitching sleeve (measures throwing biomechanics), the Zephyr Bioharness (heart rate and breathing for fatigue), Catapult GPS trackers (player workload and positioning), and the popular WHOOP strap (tracking heart rate, strain, and sleep) theupside.us theupside.us. While players can’t see this biometric data live during games, teams access it afterward to guide training and recovery. Beyond games, many clubs use sensor tech in practice – e.g. smart bat sensors (Blast Motion, Diamond Kinetics) that capture swing speed and path, and even motion-capture sleeves to monitor pitching mechanics theupside.us. In Minor League games, bat sensors are now allowed on-field to gather swing data for player development theupside.us.
- Instant Replay System: MLB’s Replay Operations Center in New York, equipped with Hawk-Eye multi-angle video feeds, has handled all umpire reviews since expanded replay launched in 2014 hawkeyeinnovations.com. Managers can challenge close plays (home runs, safe/out, etc.), triggering a rapid video review. Hawk-Eye’s system provides synchronized camera angles and even 3D renderings for officials, which has improved accuracy and consistency of calls hawkeyeinnovations.com hawkeyeinnovations.com. By the mid-2020s about half of all manager challenges result in overturned calls (reflecting the system’s thoroughness), and the average review takes under 90 seconds – faster than in early years espn.com. MLB has also equipped umpires with wireless headsets to announce replay decisions to the crowd (similar to NFL) for transparency technology.mlblogs.com.
- AI-Enhanced Broadcasting: MLB broadcasts are increasingly augmented by AI and advanced data. Statcast data feeds live graphics like strike-zone overlays, launch-angle trackers, and catch probability on TV broadcasts. In 2024, ESPN debuted a “Statcast AI” alternate broadcast for Sunday Night Baseball, layering real-time analytics and predictive modeling (powered by Google Cloud’s AI) over the game action espnfrontrow.com. Other networks have introduced new camera angles – for example, “UmpCam” helmet cameras and base-mounted cams debuted in the 2024 postseason to give fans POV replays sportsvideo.org. AI-driven systems also help production crews by automatically clipping highlights and even suggesting storylines from live data sportsvideo.org. While fully automated commentary isn’t mainstream in MLB yet, AI tools are assisting human broadcasters with instant stat insights and even real-time translations.
- Immersive Fan Experiences (VR/AR): MLB is pushing into virtual and augmented reality for fans. In 2024, the league relaunched its MLB Virtual Ballpark, a metaverse-style 3D stadium where fans can join live watch parties with avatars mlb.com mlb.com. During these events, a 3D recreation of the game (via Gameday 3D) lets fans view any play from any angle in real time, chat via spatial audio, and even partake in virtual scavenger hunts and trivia – all accessible on web or VR headsets mlb.com mlb.com. MLB has also released VR video games like “Home Run Derby VR,” letting fans step into a virtual batter’s box and swing a controller bat in famous stadiums. Augmented reality is enhancing the ballpark too: for instance, some team apps now offer AR overlays where you can point your phone at the field to see live player stats or strike zone graphics. These immersive technologies aim to bring fans closer to the game, whether they’re at home or exploring the concourse.
- Smart Stadiums and Biometric Entry: Baseball venues in 2025 are high-tech playgrounds. Digital ticketing via the MLB Ballpark app is now standard, and ballparks are integrating features like mobile concession ordering and cashless payments for speed. Several teams (Phillies, Giants, Astros, Nationals) have rolled out “Go-Ahead Entry,” a facial-recognition based gate system that lets ticket holders enter by simply walking past a camera espn.com espn.com. This opt-in system, developed with NEC Corp., links your face to your ticket account and even works with new AI security scanners – meaning fans can go from the turnstile to their seats without pulling out a phone or stopping for bag checks espn.com espn.com. “You don’t even have to break stride,” says SF Giants CTO Bill Schlough, calling the frictionless face-scan entry “an absolute game-changer” for the fan experience espn.com. However, privacy advocates worry about the creep of such biometrics – one digital rights group warns this is “just one part of a massive problem that’s only getting bigger” espn.com. Despite concerns, MLB is expanding these tech conveniences, and also experimenting with biometric payments (buying a beer with your face scan) in some venues stadiumtechreport.com stadiumtechreport.com. All 30 MLB parks now have robust 5G Wi-Fi networks to support these innovations and keep fans connected.
- New & Experimental Tech: MLB isn’t stopping at what’s already on the field. The league is exploring brain-sensing wearables and neurotraining tools to boost player performance. For example, teams like the SF Giants have tried the Halo Neuroscience headband, which uses mild electrical stimulation to the brain to improve focus and motor skill learning during training theupside.us. In 2025, a startup called Pison began pilot programs with MLB clubs and colleges for a novel wristband that measures neural signals from the brain to gauge a player’s reaction time, mental fatigue, and focus sportsbusinessjournal.com sportsbusinessjournal.com. The idea is to quantify the “mental game” – a frontier previously hard to measure – and train players’ cognitive skills (e.g. pitch recognition and split-second decision-making) with personalized neural feedback drills sportsbusinessjournal.com sportsbusinessjournal.com. On another front, MLB is working with scientists on smart equipment, like new baseball prototypes. After the 2021 crackdown on pitchers’ illegal sticky substances, MLB partnered with Dow Chemical to develop a pre-tacked baseball that comes out of the wrapper with a perfect grip foxnews.com foxnews.com. In 2023, one such ball was tested in Double-A: players loved the improved grip, but in hot weather it became “too gummy,” showing the challenges of chemistry in sport foxnews.com. The research continues (with “15 PhDs working on it,” per MLB advisor CC Sabathia) to find a ball coating that can replace the centuries-old practice of rubbing mud on baseballs foxnews.com. Other experimental projects include upgraded protective gear (e.g. smarter batting helmets to reduce concussions) and even automated groundskeeping robots in training facilities. MLB’s willingness to pilot these ideas in the minors and independent leagues signals that more radical tech changes could be on the horizon.
- MLB vs. Other Leagues: Compared to the NFL, NBA, and global soccer, MLB’s tech landscape in 2025 is both innovative and unique. In player tracking, all major leagues now capture data – the NFL places RFID chips in every football and in players’ shoulder pads to fuel its Next Gen Stats operations.nfl.com, and the NBA uses optical systems to map player and ball movements in second-by-second detail. Yet MLB’s Statcast stands out for the sheer volume of data (tracking every pitch and play of a 162-game season) and its public availability to fans. In officiating, soccer led the way with goal-line technology and the VAR replay system using Hawk-Eye cameras for controversial calls hawkeyeinnovations.com, and tennis has long trusted Hawk-Eye for line calls. MLB is now catching up by testing an automated strike zone, a bold step neither the NFL nor NBA have equivalently taken (football still relies on referees’ eyes and the old chain gang for first downs, while basketball refs use replay for some calls but no AI officiating). The NFL has embraced tech in other areas: since 2021 the NFL even uses Hawk-Eye in its replay center to speed up multi-angle reviews hawkeyeinnovations.com, and it leverages Amazon’s AI to generate stats like expected rushing yards from tracking data operations.nfl.com. NBA arenas are high-tech too, featuring giant HD scoreboards and AR effects; the NBA was a pioneer in virtual reality broadcasts (streaming select games in VR to Oculus headsets) and uses advanced Second Spectrum analytics to display things like real-time shot probabilities on TV. Global soccer at events like the World Cup has begun using semi-automated offside technology – multiple cameras and AI to detect offside positions instantaneously – something analogous to baseball’s automated pitch location tech hawkeyeinnovations.com. In terms of fan experience, all leagues now offer mobile ticketing, on-demand highlights, and interactive apps, but MLB’s Virtual Ballpark metaverse and weekly VR watch parties are the first of their kind among major sports mlb.com. And while facial-recognition entry is starting to appear in NFL stadiums and NBA arenas, MLB’s concerted rollout of biometric entry lanes in 2024 put it at the forefront of that trend espn.com. Each sport balances tradition and technology – as MLB Commissioner Rob Manfred has noted, baseball tries to “pursue the possibility of change” carefully foxsports.com. But fan sentiment is shifting: after seeing tech like ABS challenges in action, many are now more vocal in demanding high-tech accuracy over human error foxsports.com. In the grand view, MLB’s 2025 tech revolution is part of a wider sports-tech boom – yet its particular blend of preserving a 150-year-old game while infusing it with cutting-edge innovations truly sets baseball apart.
On-Field Technology Transforming MLB
Hawk-Eye Statcast Tracking System
At the heart of MLB’s on-field tech is the Statcast tracking system, which by 2025 is a fully Hawk-Eye-powered platform. In every MLB stadium, an array of a dozen or more Hawk-Eye cameras captures the 3D position of the baseball, all players, and even the bat, dozens of times per second hawkeyeinnovations.com. This generates an enormous data stream: pitch velocity, spin rate, precise location at the plate, exit velocity and launch angle of batted balls, sprint speed of runners, outfielders’ routes to the ball, and more – all measured instantly and accurately. Hawk-Eye’s optical tracking (which replaced older radar systems in 2020) is so precise it can even model the bend of an outfielder’s jump or the exact swing plane of a batter’s cut hawkeyeinnovations.com. The result is a richer statistical picture of the game than ever before.
Statcast data isn’t just for back-office analysts; it’s now a huge part of fan-facing media. Every TV broadcast shows Statcast-powered graphics – from the now-familiar strike zone box that lights up with pitch locations to superimposed trails showing a home run’s parabolic flight into the seats. In 2024, ESPN introduced a “Statcast Edition” alternate broadcast that leaned heavily on these numbers, offering real-time win probabilities and detailed pitcher vs. batter history, generated through AI models analyzing Statcast data espnfrontrow.com. MLB’s own tech team continues to roll out new metrics: for example, swing “attack angle” and bat path data are being added to help clubs and fans understand hitting mechanics sabr.org. According to MLB Statcast developer Mike Petriello, the goal is to answer deeper questions – does a given metric actually reflect a skill or strategy that matters on the field? sabr.org. This constant innovation in Statcast makes MLB a leader in sports analytics; even the NFL and NBA have tapped some of the same Hawk-Eye/optical tech for player tracking in recent years hawkeyeinnovations.com hawkeyeinnovations.com.
The impact on gameplay has been significant. Teams now deploy defenders based on Statcast spray charts and even in-game probabilities (leading to the rise of extreme infield shifts, until MLB regulated those in 2023). Pitchers design their arsenals using high-speed cameras and spin-rate data – giving birth to new pitches like the “sweeper” slider that Statcast helped identify and name. Coaches and players increasingly rely on iPads in the dugout loaded with Statcast video clips and heatmaps of opponents’ tendencies. For fans, Statcast has demystified feats like the 115 mph Giancarlo Stanton line drive or that impossible jumping catch with a 99% catch probability – we now get the numbers that make us go “wow” in a more scientific way. As one Google Cloud engineer put it, the next step is predictive analytics: using all this data to project future performance and strategize in real time, something MLB is actively developing with its AI partners sportsvideo.org espnfrontrow.com.
Automated Ball-Strike System (Robo-Umpires)
Nothing in baseball is argued over more than the strike zone, and technology is finally ready to settle the score. The Automated Ball-Strike System (ABS) uses the Hawk-Eye tracking cameras to call pitches with machine precision. While a full robo-ump (where the system calls every pitch in real time) has been tested in the minors, MLB in 2025 is favoring a more conservative approach: a challenge system. In this format, the human home-plate umpire calls balls and strikes as usual – but teams have a limited right to appeal those calls to the automated zone.
During 2025 Spring Training, ABS challenges were rolled out widely for the first time, with each team typically getting two challenges a game reuters.com foxsports.com. The process is remarkably quick: if a pitcher, catcher, or hitter firmly believes a call was wrong, they tap the top of their head (the challenge signal) immediately after the call. Within seconds, the stadium big screen shows an animated replay of the pitch’s trajectory crossing (or missing) a digital strike zone, as captured by Hawk-Eye reuters.com. The crowd roars in anticipation – it feels like a high-stakes VAR replay in soccer or a Hawkeye line call in tennis. The umpire watches the same animation on a handheld device and then announces the result: “The call on the field stands” (if the pitch was indeed off the plate) or “The call is overturned – it was a strike.” Fans saw these graphics during spring games, and the system added only ~17 seconds on average per challenge reuters.com. In one early report, about 52% of challenges led to overturned calls, meaning even the best umps were missing roughly half of the disputed pitches foxsports.com. This success rate validated what players suspected – an automated zone can correct many human errors. (Notably, data from 2024 showed humans get roughly 6-11% of calls wrong foxsports.com, which over hundreds of pitches per game causes plenty of frustration.)
The technology behind ABS is essentially Statcast on steroids. The rulebook strike zone is defined in exacting detail: the plate is 17 inches wide, and the top and bottom of each batter’s zone are set at 53% and 23% of their height, respectively reuters.com. Hawk-Eye’s system knows each batter’s height (MLB even had biomedical engineers verify measurements so they’re accurate to the inch reuters.com) and calculates the zone in real time. The zone is a three-dimensional volume – 17 inches wide and 8.5 inches deep (front to back of plate) – and the system tracks the baseball in flight to see if any portion of it clipped that volume reuters.com. If so, it’s a strike. Importantly, the software adjusts instantly for each batter’s stance; as one MLB tech expert explained, this ensures a “uniform strike zone for every batter” that is truly based on the rulebook definition reuters.com. The challenge replay that fans see is basically a freeze-frame of the pitch’s path against that zone – similar to tennis’ Hawk-Eye, but with a dynamic top and bottom based on player height.
By mid-2025, MLB’s commissioner Rob Manfred confirmed that clubs are enthusiastic about ABS and the league’s competition committee is weighing it for future regular seasons foxsports.com. “The teams are really positive about ABS,” Manfred noted, and even joked that after using it in spring, his office got more emails from fans complaining about umpire calls in games without ABS – essentially clamoring for the robo-ump full time foxsports.com. Still, purists remain cautious. The human element – catchers framing pitches or umpires establishing their own zone – has been part of baseball’s lore. To address that, MLB’s challenge system keeps umps in charge most of the time and adds drama rather than replacing them outright. Early player feedback has been largely positive; even traditionally-minded veterans adapted quickly when they saw blatant misses get corrected on the board. Controversies have been minimal so far, though some players humorously admitted they weren’t sure how to signal a challenge at first (tapping the helmet was an improvised solution). The umpiring union has been quiet publicly, but it’s clear that if ABS comes, on-field umps would simply become arbiters of the computer’s call – a significant shift in their role.
Looking ahead, MLB will continue testing in the minor leagues (where in some Triple-A games every pitch is called by ABS, with the umpire just relaying the result). The ABS hardware is already in place at most pro ballparks, and by all accounts, if approved, robo-umps could be turned on for MLB games fairly quickly reuters.com. For now, fans got a taste during the 2025 All-Star Game, where every close pitch could have been challenged in a showcase of the technology foxsports.com foxsports.com. It’s a future where strike-zone arguments might become obsolete – or at least, solved by a quick check of the digital zone rather than a dirt-kicking tirade at the umpire.
PitchCom: Wireless Pitch Calling
Another transformative on-field tech is PitchCom, which has fundamentally changed how teams communicate during games. PitchCom is a simple concept with big effects: a digitally encrypted radio system that allows a player to call pitches with the press of a button. The typical setup has been a wristband transmitter worn by the catcher, with buttons for pitch type and location. The catcher presses, say, “fastball away,” and a tiny earpiece worn by the pitcher (and any other authorized defenders, usually middle infielders) whispers the call in their native language. No hand signs, no visible cues – and thus nothing for an opposing team to steal.
MLB accelerated PitchCom’s adoption after high-profile sign-stealing scandals (most infamously the 2017 Astros using a camera to decode signals). In 2022 the system was made available to all teams, and by playoffs that year almost every pitcher-catcher battery had switched to it. “PitchCom has not only stopped sign stealing cold, but it’s also a major factor in keeping games moving at a faster pace,” one MLB blog noted pitchcom.com. Indeed, without the need for repeated mound visits or elaborate sign sequences with a runner on second, pitchers can focus on delivery. By 2023, MLB went a step further and allowed pitchers themselves to wear the transmitter if they choose mlb.com mlb.com. This was partly in response to the new pitch clock rule: a pitcher on the mound can save precious seconds by calling his own pitch (essentially shaking off the catcher without any physical gesture) and get on with it. In spring 2023, veterans like Max Scherzer and Zack Greinke experimented with this – Greinke amusingly “shook himself off” via the device until he got the pitch he wanted, as observers noted mlb.com. MLB approved it, so now either the catcher or pitcher (or both) can wear transmitters, and up to five defenders (usually pitcher, catcher, shortstop, second baseman, and center fielder) can listen in on the chosen pitch mlb.com pitchcom.com.
The technical details: Each team has a set of encrypted channels; there are preset audio clips for each pitch (teams record their own voices, often in multiple languages – PitchCom supports Spanish, Japanese, etc.). The system operates on an encrypted RF band, so opponents cannot intercept it. Early on, there were minor hiccups like crowd noise drowning out the audio or a device occasionally failing – but those issues were quickly ironed out with volume tweaks and better hardware pitchcom.com. The league mandates no device in the dugout or on offense can have access, to keep it one-way and prevent cheating.
Player reaction has been largely positive. Traditionalists initially missed the romanticism of finger signs, but the competitive necessity won out. Pitchers love that they can focus on execution without worrying about flashing complex sequences of signs with runners on base. Catchers have had to adjust – their skill in “sign sequencing” is less valued, but they still need to read hitters and call the right game. One fringe benefit: infielders knowing the pitch type can position and prepare better (e.g. a shortstop can cheat a step if he knows a changeup is coming that a batter might pull). Many credit PitchCom with preventing any repeat of sign-stealing scandals and also eliminating the paranoia that every team had in the wake of 2017. It’s now common to see a catcher tap a keypad on his shin guard rather than wiggle fingers; it’s subtle enough that casual fans might not even notice the tech on screen. In sum, PitchCom blends into the background – exactly what good tech should do – while solving a problem and improving the game’s flow.
Replay Review Systems
MLB’s instant replay review system, instituted in expanded form in 2014, relies on a robust technology backbone to get calls right. At each game, high-speed cameras capture every angle, and a wired connection sends those feeds to the Replay Operations Center in New York City. There, MLB replay officials – often former umpires or supervisors – use Hawk-Eye’s replay software to synchronize angles and zoom in on the play in question hawkeyeinnovations.com. For fans in the ballpark and watching at home, controversial plays (safe/out, fair/foul, fan interference, etc.) are now resolved in a matter of minutes with far more transparency than the old purely human eye test.
Here’s how it works: Managers have a limited number of challenges (one challenge, with a second awarded if the first is successful, plus umpire-initiated reviews in extra innings or boundary calls). When a manager signals challenge, the umpire crew chief dons a wireless headset connected to the Replay Center. In New York, technicians cue up the best camera views; Hawk-Eye’s system can tile multiple synchronized angles on a screen or even create a composite 3D rendering (especially useful for tag plays or border calls). The replay official makes the decision – either confirmed (call was correct), overturned (call was wrong), or stands (too inconclusive to change) – and that ruling is relayed to the crew chief. Starting in 2022, in a move borrowed from the NFL and NHL, MLB umpires began announcing replay results via microphone to the stadium, saying e.g. “The call is overturned, the runner is safe at second” technology.mlblogs.com. This was enabled by the same wireless comms system that ABS uses, making the process feel much more fan-friendly and immediate.
Statistically, replay has indeed corrected a lot of mistakes. In recent seasons, roughly 50% of challenged calls have been overturned upon review sabr.org. The average review time has come down to around 1 minute 20–30 seconds espn.com, which is faster than early years where 2+ minutes was common. MLB achieved this through tech upgrades like direct fiber links from each ballpark to NYC and the Hawk-Eye upgrade in 2018 (replacing older replay tech). All 30 stadiums have calibrated camera systems, and since every close play is captured from multiple angles (including super slow-motion cameras at 300+ FPS for key bases), the fidelity of evidence is high. There have still been a few controversies – fans occasionally see an angle on TV that looks like one outcome, but MLB might have another angle that shows the opposite, leading to confusion. But by and large, replay tech has increased confidence in officiating. As Mike Murphy, the NHL’s SVP of Hockey Ops, aptly said about Hawk-Eye’s replay in another sport: it “helped drive consistency in the decisions we make on a nightly basis; something our teams and fans rely on.” hawkeyeinnovations.com The same is true in baseball now.
One interesting aspect is that MLB’s replay tech paved the way for the ABS challenge system. The habit of showing close calls on the scoreboard and having an official “review” is now ingrained in the sport. Fans in 2025 are used to waiting that 60-90 seconds for a final verdict while perhaps seeing the slow-mo themselves. The ABS strike zone challenge is essentially a mini-replay for every pitch, just extremely fast – a direct descendant of the replay culture MLB built. So while replay review doesn’t have the same futuristic vibe as robo-umps or VR, it was the crucial first step in bringing high technology onto the diamond to assist officiating.
Player Wearables and Biometric Tracking
MLB players in 2025 are becoming cyborgs in subtle ways. Over the last decade, the league has carefully allowed wearable sensors to monitor players’ health and workload, making baseball one of the first major leagues to permit such devices in live games theupside.us theupside.us. The rationale is simple: a 162-game season is an endurance trial, and any edge in recovery or injury prevention is golden.
One of the earliest approved devices (2016) was the Motus Baseball Sleeve, a compression sleeve with an embedded sensor that tracks the stress on a pitcher’s elbow (UCL) each throw theupside.us. Given the epidemic of Tommy John surgeries, teams were eager for data on how fatigue or mechanics affect ligament strain. Another was the Zephyr Bioharness, a small chest strap that measures heart rate, breathing rate, and movement – essentially a proxy for a player’s in-game conditioning and stress level theupside.us. By wearing it during games or intense practices, trainers can tell if a player is overexerting or not fully recovered.
MLB didn’t stop there. It later okayed the Catapult GPS system, a little sensor typically worn in a pouch on the back of a player’s undershirt, which logs every movement on the field – total distance run, sprint bursts, etc. theupside.us. Soccer and rugby players have worn these for years; in baseball, they’re useful to track outfielders’ routes or a catcher’s crouch time. The fourth big wearable was the WHOOP strap, approved in 2017 – a wristband that logs heart rate variability, sleep quality, and other physiological data theupside.us. Notably, WHOOP data captured a now-famous moment in 2016 when a Red Sox player’s heart rate spiked to 160+ during a diving catch, giving fans a direct window into the stress of an incredible play. That helped convince MLB to allow it in competition.
A key point: during games, teams do not get live feeds of biometric data (to prevent any real-time strategizing or privacy issues) theupside.us. The data is downloaded afterward. Even so, players often check their WHOOP or other stats post-game to see how their body responded to a long outing or an extra-inning marathon. And teams are building vast databases – for instance, correlating a drop in a pitcher’s arm speed (from the Motus sleeve) with impending elbow soreness, or noting that a player’s recovery score (WHOOP metric) tends to dip in day games after night games, so maybe adjust his rest. It’s a new era of sports science in baseball. The players’ union keeps an eye on privacy – agreements stipulate that such data can’t be used punitively in contract negotiations, for example – and participation is technically voluntary. But many players opt in, figuring it can only help their longevity.
Beyond these in-game wearables, MLB clubs deploy a myriad of gadgets in training. Force plates in batting cages measure how well hitters use their legs. High-speed Edgertronic cameras (up to 1000 fps) combined with ball-tracking radars (TrackMan, Rapsodo) are standard in bullpens to refine pitches. There’s also a growing use of neurotech for training – the Halo Neuroscience headset, for instance, sends mild electric currents to the motor cortex; the SF Giants used it to help players warm up their brains before workouts, claiming it improved focus and strength output theupside.us. Another tool, neurofeedback via EEG headbands (like the Muse or products by companies such as Alphabeats), has been tried to improve players’ mental resilience by training them to control their brainwaves under pressure. And in a crossover of gaming and neuroscience, companies like GameSense offer vision training apps where players practice pitch recognition on a tablet – essentially brain training to recognize pitch types faster theupside.us theupside.us.
What’s the reception? Younger players are generally enthusiastic – today’s prospects come up with wearable tech as part of their development. Older veterans have been more skeptical at times (some bristled at wearing a monitor, fearing data could be used against them). But as wearables proved their worth – say, flagging fatigue before an injury happens – the culture shifted. By 2025, having a biometric dashboard for a player is as normal as having his batting average. It’s telling that while the NBA forbids in-game wearables, MLB embraced them early theupside.us. Baseball’s slow pace and discrete plays actually make it easier to collect and integrate this data without disrupting play. The sport that once shunned even batting gloves now has players wearing smart straps and sleeves under their uniforms, largely invisible but very impactful. In coming years, expect even more integration – perhaps real-time alerts if a pitcher’s arm angle drops (a sign of fatigue), or smart ballparks that automatically track player vitals as they step on the field. The line between athlete and cyborg is blurrier, but the upside is longer careers and fewer injuries, which everyone can cheer for.
Smart Bats, Balls, and Equipment Innovation
While players themselves are getting wired up, so too is their gear. MLB has seen a wave of equipment innovation aimed at improving performance and safety. One area is the baseball bat – traditionally a simple piece of wood. These days, however, teams want to know everything about a swing. Bat sensor mounts have become common in batting practice: devices like Blast Motion or Diamond Kinetics sensors can attach to the knob of a bat and provide metrics on swing speed, swing plane, time to contact, and bat angle theupside.us. In the minor leagues, MLB went a step further by approving the use of Blast Motion’s sensor even during games (at least in lower-level leagues and complex leagues) theupside.us. This means a prospect’s every swing in a live game can be recorded and analyzed – whether his swing is getting loopy or if his approach changes against different pitch speeds. Such data was once only available via video and scouting eyes; now it’s measured in degrees and milliseconds. There’s even talk of manufacturing bat handles with embedded chips so players don’t need to attach a sensor – the tech would be built into the bat knob (MLB would have to approve that for game use, but it seems like a logical next step).
The baseball itself has been a focus of innovation, especially concerning its consistency and grip. After years of fluctuating offense levels (the “juiced” ball vs “dead” ball debates), MLB took ball production in-house with a aim for uniformity. The newer twist is the pre-tacked baseball: a ball with a slightly sticky surface out of the package, mimicking the feel that pitchers get when they rub the ball with special mud (a daily ritual currently). Japanese and Korean leagues have used pre-tacked balls successfully, and MLB has been testing their own formula. In early 2023, MLB introduced a prototype ball in the Double-A Southern League – it came in a foil pouch to preserve the tackiness foxnews.com. Pitchers initially loved it; they could grip their breaking balls without smearing on sunscreen or pine tar. But as summer hit, an issue emerged: the heat made the coating too sticky and “gummy,” affecting play foxnews.com. So that version was shelved mid-season. As CC Sabathia (now an MLB advisor) explained, the league continues working with Dow Chemical scientists on a better recipe, but even “15 PhDs” on the case haven’t yet cracked Japan’s secret formula foxnews.com foxnews.com. One funny snag: the test balls were gleaming pearl white (since they weren’t rubbed with mud), and pitchers said they were too white – hitters could pick up the ball easily, and players just weren’t used to seeing a pure white ball in play foxnews.com foxnews.com. Such are the challenges of changing a piece of equipment that’s been virtually unchanged for a century. Still, it’s likely only a matter of time before MLB introduces a standardized pre-tacked ball, which would improve fairness (every park, every ball same grip) and further reduce pitchers’ temptation to apply foreign substances.
Other equipment strides include protective gear. After some scary incidents of line drives hitting pitchers, MLB approved optional padded caps for pitchers and tighter-flung helmets for batters. By 2025, almost all batters wear helmets with an extended flap (the “C-flap”) guarding their jaw – an innovation of the last decade that caught on rapidly after some high-profile beanings. There’s R&D into smart helmets that could measure the G-forces of an impact (like the NFL does with helmet sensors) to better handle potential concussions. Baseball gloves are also seeing high-tech love: companies have experimented with sensors in the mitt to measure catch pressure and technique (mostly for training purposes). Even the humble bases on the field changed in 2023 – they became slightly larger and lower profile to improve player safety on slides, and though that wasn’t a digital tech change, it exemplified MLB’s willingness to tweak equipment for better outcomes.
Lastly, a fascinating area is field technology. While the grass and dirt might seem off-limits to high tech, MLB groundskeepers are starting to use tools like moisture sensors under the infield to optimize play conditions (a firm, fast infield vs a softer one can be adjusted by watering, guided by sensor data). Some stadiums have robotic lawn mowers (on an overnight Roomba-like schedule) and laser-guided line painters to ensure perfection. These are quiet enhancements, but they contribute to a consistent, high-quality playing surface – which is the literal foundation of the game’s integrity.
In summary, from the bat in a player’s hands to the ball hitting the glove, subtle innovations are making baseball equipment smarter and safer. These technologies often operate behind the scenes, but they collectively push the sport into the future without changing its essence – a tricky but worthwhile balancing act.
Off-Field Technologies Enhancing the MLB Experience
AI-Powered Broadcasting and Data-Driven Coverage
The way we watch baseball in 2025 is being reinvented by artificial intelligence and big data. Broadcasts have become a symbiosis of human storytelling and machine-generated insights. One major development is the use of AI to enhance live commentary. While play-by-play announcers are still human (and beloved), they now have AI tools feeding them real-time nuggets – for example, an AI system might instantly recognize that a pitcher just threw his 10,000th career pitch or that a batter’s homer traveled the longest distance at that stadium in 5 years, prompting the commentator to relay that tidbit. Some networks have experimented with AI-driven graphics that pop up automatically: when a runner steals a base, the system might flash the pop time (catcher’s throw speed) and the runner’s top sprint speed, without any researcher having to dig it up.
In 2024, MLB media partnered with technology firms (like Google Cloud, Adobe, and AWS depending on the case) to create automated highlight packages. An AI reviews the live feed and, using crowd noise, player reactions, and historical context, identifies the most exciting plays to cut into a highlight reel almost immediately. This means that by the time the 9th inning ends, fans can already see a curated highlight montage on the MLB app or social media. The AI isn’t perfect – sometimes a routine play with a loud crowd (like between-inning entertainment) might confuse it – so human editors still refine the outputs, but it has significantly sped up the content turnaround.
Personalized streaming is another area. MLB.tv (the league’s streaming service) introduced features where an AI can provide a custom audio commentary for certain games, geared to different audiences. For example, a novice feed might explain rules and player backgrounds (AI voice: “That’s strike three – in baseball, the batter is out after three strikes”), whereas an advanced sabermetrics feed might be peppered with statcast data and strategy insights. These are typically optional secondary audio streams, and they showcase the potential of AI voices in sports. (Notably, a few minor league teams even tried fully AI-generated announcers for cost-saving in 2023, though the reception was mixed – hardcore fans missed the emotion and nuance a real announcer provides.)
A particularly exciting innovation was the “TNT MLB DataCast” during the 2024 postseason. WarnerMedia offered an alternate broadcast on their app where the entire visual presentation was an animated 3D recreation of the game with live data overlays sportsvideo.org sportsvideo.org. Viewers could see player icons moving on a field diagram in sync with the real game, with constantly updating stats bubbles (like “99% catch probability” on a deep fly ball). It was a bit like watching a video game version of the live game, driven by real Statcast data. This appeals to the younger, tech-savvy audience and hardcore stat nerds. ESPN’s Statcast alternate broadcast on select Sunday nights is similar – a blend of live video and graphic overlays, with the commentary team (including MLB analyst Mike Petriello) focusing on analysis of strategy and stats rather than traditional play-by-play espnfrontrow.com.
Behind the scenes, AI is also helping camera operations. Companies like Pixellot have developed AI-driven cameras that automatically follow the action (widely used in minor leagues and amateur games) pixellot.tv. While MLB’s broadcasts still use professional camera crews, some spring training games and lower-tier productions use these automated systems to reduce cost. They track the ball and players using computer vision – though amusing failures (like a camera following a bird instead of the ball) have mostly been ironed out by improved algorithms.
One more subtle use of AI: real-time translation and closed-captioning. MLB has a diverse international fanbase and player pool. AI-driven translation can provide almost live subtitles or alternate language commentary. By 2025, the league offered Spanish commentary for every game, some of which is human, but supported by AI for quick deployment. Even Mandarin or Korean commentary for certain games (especially involving Ohtani or other international stars) have been tested using AI voices trained on native speakers. This is improving accessibility and reach, without needing a full broadcast crew in every language.
In summary, AI’s role in MLB broadcasting is like a supercharged assistant – crunching numbers, finding patterns, and even directing cameras – all to enrich the viewer’s experience. It’s making broadcasts more informative and interactive, and it’s doing so largely behind the curtain, complementing the human element of sports storytelling rather than replacing it.
Immersive Viewing: VR, AR, and the Virtual Ballpark
Imagine watching a baseball game not from the stands or your couch, but from a virtual stadium where you can choose any vantage point – behind home plate, next to the dugout, or even hovering above center field. That’s exactly what MLB’s Virtual Ballpark offers. First unveiled as a tech demo during the 2022 All-Star festivities and refined through 2023, the Virtual Ballpark became a regular offering in 2024: each Wednesday, MLB hosted interactive watch parties for a live game in this virtual environment mlb.com mlb.com. Fans from around the world could log in (for free) via their phone, computer, or VR headset, appear as avatars, and watch a real MLB game stream together. The experience included a 3D recreation of the ballpark and the on-field action, powered by Gameday 3D, synchronized to the live TV broadcast mlb.com. This meant if a fan in the Virtual Ballpark wanted to see a replay of a diving catch from the fielder’s perspective, they could essentially “teleport” their view and see a rendering of the catch in 3D from that angle. It wasn’t hyper-photorealistic, but it was good enough to feel like being on the field.
The social aspect was big: fans in the virtual venue could talk via spatial audio (meaning you hear nearby avatars as if they’re next to you) and even do fun activities like virtual scavenger hunts hidden around the digital stadium mlb.com. MLB added mini-games and trivia during breaks, and there were digital “merch” rewards (like special avatar jerseys) for participation mlb.com mlb.com. Essentially, it’s mixing the live game with the interactivity of a video game and the community of a group chat. For younger fans or those far from their team’s market, it offers a sense of “being there” that traditional TV can’t provide.
Virtual Reality (VR) in a more literal sense has also been used for consuming games. MLB has had a partnership with Meta (formerly Oculus/Facebook) to stream a selection of games in VR. Using the MLB VR app on a headset, you can sit in a virtual suite in a ballpark and watch the game on a massive virtual screen, or in some cases, see a stereoscopic 180° view from a fixed point in the stadium (like behind home plate). The Home Run Derby has even been broadcast in VR with multiple 360° cameras on the field, which was a hit for those who tried it. While VR viewership numbers are still niche, MLB is ensuring it has a foot in that door as the technology improves.
Augmented Reality (AR) is finding a place both at home and in the stadium. At home, imagine pointing your phone at your TV during a game and seeing extra stats pop up around the players on screen – that’s one concept under development. Already, apps like MLB At Bat allow a form of AR where you point your phone at your living room floor and see a 3D model of the field with the players’ live positions and stats (so you can literally visualize defensive alignments or runners on base in your space). It’s like having a holographic scoreboard on your coffee table. In stadiums, some teams have AR features in their venue apps: e.g. you scan a QR code on the seat or a section of the ballpark and it might show a historical highlight video superimposed on the field, or a kids’ AR experience where a cartoon player poses for a selfie with you via your phone’s camera.
Another facet of immersive tech is 360° video and holograms. MLB has occasionally used a 360° camera rig during special events (like the Field of Dreams game or international series) and released the footage for fans to explore. They’ve also done experiments with volumetric capture – for instance, creating a hologram of a famous play that fans could view from all angles on a Microsoft HoloLens or similar AR headset. These are early-stage experiments, but they hint at a future where fans with AR glasses might see the game from any perspective in real time, or bring up holographic replays in front of them with a gesture.
The driving idea is to break the limitation of the fixed camera broadcast. Baseball has so many subtleties happening at once on the field, and traditional TV can only show one angle at a time. VR/AR and interactive media let fans take control of how they experience the game. It’s a response to the modern viewer’s expectations: younger audiences raised on video games want agency, not a passive one-size-fits-all feed. MLB’s virtual and augmented reality ventures are an answer to that, and while not every fan will don a headset or fiddle with AR apps, those who do are getting a fresh perspective on a very old game.
Smart Stadiums: Enhancing the Live Experience
Attending a ballgame in person in 2025 brings together old traditions and new tech conveniences in equal measure. Ballparks have been steadily upgrading to become “smart stadiums”, focusing on frictionless service and fan engagement. A prime example is the earlier-mentioned biometric entry system. Traditional turnstiles and manual bag checks are gradually being supplanted by AI-powered systems. Fans who opt in to Go-Ahead Entry simply enroll a selfie through the MLB Ballpark app; at the gate, a facial authentication camera recognizes them in seconds, and they walk right in espn.com. Simultaneously, new security scanners (often millimeter-wave scanners like upgraded versions of airport tech) mean fans don’t always have to empty pockets or have bags searched – the scanner’s AI can flag suspicious items automatically. This has drastically cut down entry wait times at parks like Citizens Bank Park and Oracle Park, which were early adopters of the face-scan gates. One privacy safeguard MLB touts is that it uses facial authentication (matching your provided selfie to your face) rather than broad facial recognition (scanning everyone against a watchlist) stadiumtechreport.com stadiumtechreport.com. In other words, it’s opt-in and just replaces your ticket, rather than surveilling the crowd for unknown faces (though some venues, especially abroad, do use the tech to catch banned fans stadiumtechreport.com). The debate over privacy continues – organizations like the ACLU have voiced concern about any use of face tech at sports events aclu.org – but many fans, especially season-ticket holders, embrace the convenience. Surveys show younger fans are generally willing to trade biometric data if it means skipping lines stadiumtechreport.com.
Once inside, technology continues to streamline the experience. Mobile ordering is prevalent – you can order hot dogs and beers from your seat via an app and get a notification to pick them up (or even have a runner deliver to certain sections). Some stadiums experimented with “checkout-free” concession stands, where cameras and shelf sensors detect what you take (like an Amazon Go store) and charge your app automatically stadiumtechreport.com. A few parks introduced “beer with your face” – tying your age verification (driver’s license scan) and payment to your face so you can walk up to a kiosk, have a camera verify you, and pour a drink without showing ID or credit card stadiumtechreport.com stadiumtechreport.com. It’s still novel and only in limited sections, but it’s eye-catching (and slightly eerie to some). The reason behind all this: to reduce “friction” and get fans out of lines and back to enjoying the game (and yes, presumably spending more money per minute of game time) espn.com espn.com.
The MLB Ballpark app itself is a central hub. By 2025, it not only holds your tickets and parking pass, but offers interactive maps (with AR wayfinding to guide you to your seat or the nearest nachos stand), trivia contests and prize giveaways during the game, and integration with loyalty programs (like check in at games to earn points for merchandise). Some teams have integrated fan engagement platforms where you can vote on the next stadium pump-up song, or participate in a live trivia quiz in the middle innings with the results shown on the scoreboard. The days of the purely passive spectator are ending; fans are encouraged to be part of the action via their smartphones.
To support all this, stadiums have had to beef up infrastructure – notably, 5G wireless coverage and improved Wi-Fi. Many parks partnered with telecom companies so that tens of thousands of fans can Instagram their experience or stream replays without the network crashing. In fact, MLB’s ABS pitch challenge system itself uses 5G to quickly send data and replays during those reviews foxsports.com, showing that the stadium network is now mission-critical even to the gameplay.
Entertainment tech in stadiums has also advanced. Scoreboards keep getting bigger and sharper – 4K HDR giant screens that can split into multiple info panels. Sound systems are more immersive. Some parks have experimented with drones for post-game light shows or delivering the game ball (one MiLB team even had a drone deliver the first pitch ball once). Robotics occasionally show up – a few parks have robot helpers like beer-making robots (a novelty stand) or even roaming robot mascots that take photos with fans.
Finally, a focus has been on accessibility and inclusivity through technology. For fans with disabilities, apps can provide closed captioning for PA announcements or broadcast audio description for those with visual impairments. Some stadiums added “sensory suites” with relaxed environments and VR monitors for fans on the autism spectrum who might need a break from the noisy crowd – blending a controlled tech space with the live game.
The key theme is that the live baseball experience is becoming augmented by technology at every turn – but if done right, it’s almost invisible. The best tech just makes the fan smile at how easy or fun something was without really thinking about the circuitry behind it. MLB clubs know they must compete with the comfort of the home viewing experience, so the ballpark of 2025 is pulling out all the stops to make attending in person feel futuristic yet effortless.
Fan Engagement and Interactive Platforms
In the modern sports landscape, engaging fans beyond the nine innings is crucial. MLB has rolled out numerous interactive platforms and content to keep fans invested before, during, and after games. One prominent example is the rise of second-screen experiences. While a fan watches a game on TV, they might also be on the MLB app or a team’s app participating in prediction games (e.g., “Guess if the next batter gets on base to win points”) or chatting with other fans in moderated live game threads. MLB has encouraged teams to develop these second-screen offerings to cater to the highly interactive habits of younger viewers.
Social media remains a huge avenue for engagement, and MLB was relatively early among leagues in embracing internet culture. By 2024-2025, many MLB teams operated like media companies – with YouTube series, TikTok challenges, and interactive Twitter polls. Some even used AI-driven tools to create highlights or recaps tailored to individual fans (“hyper-personalized highlights”). For instance, if you’re an app user who always follows a certain player, the app might notify you with a short compilation of just that player’s key moments right after each game.
Fantasy baseball and sports betting (where legal) have their hooks in engagement too. MLB’s Statcast data has been a boon for fantasy stats and predictive betting models. The league struck partnerships with betting companies to integrate live odds and predictions in broadcasts and apps, carefully walking the line to not alienate traditional fans. By providing real-time data and even AI predictions of outcomes, they keep that segment of fans glued to every pitch because something is on the line for them beyond just the score.
The MLB Fan Cave concept from earlier years evolved into digital form – now we see things like MLB Home Run Derby X (an event and also a video game/streaming series) to capture international and casual fans. Additionally, MLB’s involvement in esports-like experiences (such as “Out of the Park Baseball” simulations or VR baseball competitions) provides more touchpoints for fans to interact with the sport in the digital realm. Even the venerable baseball card got a tech makeover: NFT collectible moments were experimented with in 2022-23, and by 2025 MLB has an official NFT platform where fans can buy unique digital highlight clips or even use them in a fantasy-style blockchain game. Uptake has been moderate (the NFT craze cooled), but it’s part of the array of offerings.
One fun and somewhat quirky platform is MLB Film Room – a website/tool MLB released that lets fans easily search and clip any video from MLB’s enormous archive. Fans can create their own highlight reels and share them. It’s both a research tool and an engagement toy, and it leans into the fact that baseball’s history and stats are a treasure trove for content creation. Many viral Twitter videos of classic moments or player comparisons come straight from fans using Film Room and Statcast data to illustrate a point.
Another engagement initiative is community and content creation. MLB has tapped popular YouTubers and influencers to produce baseball-related content, recognizing that a TikTok about crazy pitches or a Twitch stream of someone playing MLB The Show can hook young audiences. Some teams have “creator nights” where they invite influencers to the ballpark and give them behind-the-scenes access for their vlogs, effectively enlisting them as ambassadors to their followers.
All these platforms underscore a reality: the days of simply broadcasting games and expecting undivided attention are over. MLB is meeting fans where they are – on phones, on social media, in the metaverse – and giving them many ways to participate. The goal is to make following baseball a 24/7 interactive hobby, not just a three-hour passive watch. By 2025, fans have an unprecedented level of access and input. You can tweet a question to the team’s analyst and maybe get it answered on air, or vote in an app poll that decides which throwback uniform the team will wear on a retro night. This two-way interaction has made fans feel more connected to the sport and its players (who themselves often engage via social media or even post-game Zoom Q&As for fans). It’s a tech-fueled democratization of the fan experience: no matter where you live or who you know, you can have a voice in MLB’s big conversation online.
New and Experimental Technologies on the Horizon
Robotic Umpires and the Future of Officiating
The ABS challenge system discussed earlier is just the tip of the iceberg – MLB’s endgame could be a fully robotic home plate umpire. In minor league trials (like in the Triple-A Pacific Coast League), MLB has already used the full ABS: no human balls/strikes at all, every pitch call comes from the system and is fed to the umpire via an earpiece. The human ump merely announces it. Players found it a bit jarring at first – there’s no room for argument or persuasion when a call comes from the computer. But many pitchers and hitters actually appreciated the consistency. One quirk: the automated zone is absolute. So a 12-6 curveball that nicks the very front-bottom of the zone (below the batter’s knees as it crosses the front of plate but then dives into the dirt) will be a strike by rule. Human umps often call that a ball because it looks bad to the eye or the catcher catches it low. With robo-umps, you might see more strikes at the bottom that players have to adjust to swing at. Some worry this could change the shape of the game – favoring certain pitching styles. That’s why MLB has been cautious, using the challenge system as a hybrid approach for now technology.mlblogs.com technology.mlblogs.com.
But the momentum is there. By 2024, ABS was used in most Triple-A games (some nights with full automation, some with the challenge format) reuters.com. The results and feedback from those will guide MLB’s next steps. One possible outcome is a mix even in MLB: perhaps they adopt the challenge system permanently, or perhaps certain counts or late-game situations allow a challenge. There’s also the factor of broadcasting – as seen, when fans can literally watch the strike zone graphic live, it might be harder to accept egregious misses in crucial moments. The public might demand the computer’s justice. It’s telling that in tennis, once players and fans saw how accurate and quick Hawk-Eye line calls were, the sport moved to embrace it fully (some tournaments even removed line judges entirely by 2021). Baseball could be on a similar trajectory for balls and strikes.
Beyond balls and strikes, could we see automated base safes/outs? Possibly, though that’s trickier because it involves a lot of physical factors (did the first baseman keep his foot on the bag? etc.). However, tech is creeping in: the NFL, for instance, now has chips in balls that – while not yet used to spot first downs automatically – are being used in experiments to aid decision-making foxsports.com. MLB could hypothetically put sensors on bases and have players wear tags to instantly judge if the runner touched before the tag, etc. At the moment, replay covers most of that. But maybe one day, the replay will be instantaneous via AI, removing the need to stop play at all.
One experimental tech that has been used: the automated strike zone for pitch training. Teams have installed pitching machines with advanced vision systems to call balls and strikes during bullpens, giving pitchers immediate feedback on whether their cutter is consistently hitting the black or just off. It’s not glamorous, but it shows how ubiquitous such tech could become at all levels of baseball.
Brain-Tech and Neural Wearables
We touched on neurotech in training – this is an area that could explode. By 2025, a company called Pison made waves by launching what it billed as baseball’s first mental performance platform sportsbusinessjournal.com sportsbusinessjournal.com. The Pison system uses a wearable (like a high-tech wristband) that actually reads electrical signals from the brain and nerves as they manifest in muscle activity sportsbusinessjournal.com sportsbusinessjournal.com. In practice, a player might wear it while doing a series of quick reaction drills on a tablet or VR headset. The device measures things like reaction time, decision-making speed, and perhaps stress responses. The goal is to quantify traits like focus and “baseball IQ” that were previously intangible. It’s almost like a Combine for the mind – can a prospect track a 90 mph pitch mentally and make the split-second right choice to swing or not?
Early adopters include some college programs and reportedly “multiple MLB teams” evaluating it sportsbusinessjournal.com sportsbusinessjournal.com. If it proves useful, it could change scouting and training: teams might start looking at a player’s cognitive metrics alongside their batting average. Did a batter struggle because his processing speed for pitch recognition is below average? Now you might measure that and then use specialized training to improve it. There’s also an element of mental load management – perhaps a device can tell if a player is mentally fatigued (similar to how a WHOOP might tell if he’s physically fatigued) and needs a day off to be sharp.
Another frontier is virtual reality training. A few years ago, the Tampa Bay Rays and other teams started using VR to let hitters practice against virtual versions of real pitchers. A company called WIN Reality (the evolution of an earlier startup) provided a system where a player wearing a VR headset can “face” a 3D avatar of, say, an opposing pitcher, with that pitcher’s exact delivery and repertoire, all based on real tracking data theupside.us theupside.us. The Mets were known to use this regularly – hitters would take VR at-bats in the clubhouse before a game to get used to an unfamiliar pitcher’s release point and pitch shape. Chili Davis, a longtime MLB hitting coach, praised it as “the next level of looking at video… an advanced visualization tool” with real benefits if used right theupside.us theupside.us. By 2025, many teams have VR setups for both hitters and pitchers (pitchers can practice situational pitching to a virtual batter, or fielders can take virtual reps). It’s not wearables on the field, but it’s technology directly interfacing with players’ brains in preparation – effectively training the mind’s eye.
One could imagine even more sci-fi tech soon: maybe EEG headsets in the dugout to monitor a player’s concentration or stress in real time (though the players’ union might bristle at that level of monitoring). Or perhaps neurofeedback games players do in their downtime that have been shown to improve focus (some teams already do simple meditation and breathing training, sometimes aided by apps). The competitive edge in pro sports is so small that if brain-tech provides even a 1% improvement, teams will dive in. The challenge is doing it in a way players buy into (no one wants to feel like a lab rat or that “Big Brother” is measuring their every thought).
Other Experimental Innovations
Beyond the big-ticket items, MLB is continuously tinkering on the margins with tech. For example, in umpire training, there’s talk of using automated ball-strike data to grade and coach umpires – essentially training the humans with the robot’s feedback, to improve consistency even when calling games without ABS. In player development, biomechanics labs are now common: some teams have installed markerless motion-capture systems (like 12-camera setups or even Hawk-Eye’s skeletal tracking, which is used in some basketball leagues) to analyze pitchers’ deliveries in 3D down to joint angles hawkeyeinnovations.com. This helps identify injury risks or suggest mechanical tweaks.
Analytics and AI in strategy is another experimental zone. Could an AI help a manager decide when to pull a pitcher? We’re not far from that. Front offices use machine learning to simulate games thousands of times and optimize decisions. In 2024, an MLB club (anonymously) revealed they used an AI model to script some pitching changes and defensive shifts, essentially giving the manager an AI-suggested plan before the game. The manager still exercises judgment, but as younger, more data-native managers come up, they may lean more on such tools. A few bad outcomes might be chalked up to “the computer said so,” which could become its own controversy if fans perceive a manager as just following a script.
Fan-facing experiments also continue. One interesting pilot in 2025 was an AR baseball card display – at certain parks, if you pointed your phone at the big scoreboard when a player’s stats were up, an AR overlay would show a “virtual baseball card” of that player with video highlights playing on the card. It’s a fun blend of nostalgia (baseball cards) and modern AR. Another fan test: holographic mascots – using AR, a team had their mascot appear via people’s phone cameras dancing on the field during inning breaks (in reality, nothing was there, but on the app’s AR view, it looked real).
On the broadcast side, we might see experiments like mic’ing up more players and using AI to automatically mute the mics when sensitive info is spoken (to avoid what happened in the past where a live mic caught some profanity or strategic talk). Or automated camera drones tracking the game from new angles – a few games have tried drone shots from above during breaks, but one day a drone might follow a home run ball from home plate all the way into the stands, giving a bird’s eye view.
In essence, MLB treats the minor leagues and spring training as a tech laboratory. The Atlantic League and Arizona Fall League often get the wildest trials – from automated strike zones to movable mound distances to different base sizes. Not all are strictly “technology” (some are rule changes), but technology often enables those experiments (e.g., moving the mound back one foot was measured and monitored with TrackMan data to see the effect on pitch velocity and break). The partnership between MLB’s tradition and its technology is closer than ever: each potential change is analyzed with advanced data, and each tech advancement is measured by how it affects the tradition (e.g., will robo-umps upset the game’s familiar rhythm? Will too much information overload players or fans?).
One thing is certain: the MLB of 2030 will likely incorporate many of the experimental things we’re seeing now in 2025. As fans and players acclimate to each new tech – whether it’s a strike zone graphic or a biometric scan – yesterday’s sci-fi becomes today’s normal. MLB, once criticized as old-fashioned, is now often at the cutting edge of sports innovation, carefully blending bytes with baseball to keep the sport thriving for the next generation.
MLB’s Tech Landscape vs. Other Sports
It’s illuminating to compare MLB’s technological journey with that of other major sports leagues:
- Accuracy and Officiating: Baseball’s use of Hawk-Eye for an automated strike zone has parallels in other sports. Tennis was a pioneer with Hawk-Eye line calls starting in the 2000s, which set the precedent that players and fans would trust a computer over a fallible human. Soccer introduced goal-line technology (also Hawk-Eye cameras) in 2013 after a few too many “ghost goals.” Now, every top soccer league uses it – a sensor tracks if the ball fully crosses the goal plane, providing a yes/no within a second, removing any doubt hawkeyeinnovations.com. Soccer also has VAR (Video Assistant Referee) since late 2010s – similar to MLB’s replay in concept, with off-field refs reviewing footage. Interestingly, soccer’s VAR has had its share of controversy, partly because the laws (like offside) can be very tight and decisions sometimes hinge on 3D technology drawing lines to a player’s toe. MLB’s challenges with replay and ABS are analogous, but baseball might benefit from learning from soccer’s growing pains in communicating decisions clearly and not overusing tech to where it disrupts flow. The NFL, by contrast, has been more cautious with automated officiating. They still have humans measuring first downs with chains – almost quaint by today’s standards. However, as noted, the NFL did incorporate Hawk-Eye in 2021 for centralized replay to speed things up hawkeyeinnovations.com. They have also quietly put RFID chips in footballs and pylons, which could theoretically be used to spot the ball electronically sports.yahoo.com, but the margin of error (about 6 inches currently sports.yahoo.com) means it’s not yet ready to replace the chain gang. In 2022, the NFL tested a “Hawk-Eye” like system in the Pro Bowl to automatically judge in/out of bounds, but it’s in early days. Meanwhile, the NBA uses replay mostly for late-game out-of-bounds or flagrant foul reviews, and in 2023 they introduced a coach’s challenge similar to MLB’s (one per game). But the NBA hasn’t pursued an automated whistle (e.g., there’s no technology calling fouls or violations automatically – that remains human). So in the realm of officiating tech, MLB is arguably at the forefront with the ABS concept, second perhaps to tennis and soccer in specific use cases.
- Player & Ball Tracking: All major sports now have some tracking system:
- The NFL’s Next Gen Stats uses Zebra’s RFID tags in every player’s shoulder pads and in footballs to log position and speed data 10 times per second operations.nfl.com operations.nfl.com. This yields metrics like how fast a receiver ran or how much separation a DB allowed. On broadcasts, fans see things like “Tyreek Hill reached 22.5 mph on that touchdown run (fastest of the season).” It’s become a part of NFL storytelling. The chips in the ball also measure throw speed and rotation. However, because the NFL’s play-by-play is start-stop, the data is mostly used for post-play analysis or cute graphics (like showing the route a receiver ran).
- The NBA initially (2014) installed SportVU cameras in arenas for player tracking, then moved to a system by Second Spectrum (now part of Genius Sports) which does optical tracking and even real-time AI indexing of plays. The NBA can now quantify things like a player’s average speed on defense, the probability of a shot going in the moment it’s released, or who was responsible for defensive rotations. For fans, the impact is subtle but present – telecasts might show an overlay of how a play developed or the % chance a shot had based on distance and contest. And in 2023, the NBA even experimented with a “coach’s clipboard” AR on their app, letting fans see an overhead diagram of plays drawn from the tracking data.
- Soccer recently integrated a system where a sensor in the ball plus limb-tracking cameras assist with offside decisions (semi-automated offside, used in FIFA World Cup 2022). They also use optical tracking for player running distances, speeds, etc., and many elite soccer players wear GPS vests during matches (FIFA allows it) to monitor load. However, soccer data isn’t as visible to fans during broadcasts beyond the occasional “so-and-so ran 11 km today” stat.
- Fan Experience and Venue Tech: All leagues are modernizing stadiums, but MLB parks, many of which are older and charming, face the challenge of updating without losing character. Many MLB teams have successfully integrated high-tech amenities (like apps and VR attractions) while preserving traditions like the 7th-inning stretch and keeping score by hand if you want. NFL stadiums tend to be newer and have gone full tech – giant jumbotrons, flashy AR shows (the Baltimore Ravens did an AR crow that flew around the stadium via the big screens, for example), and heavy use of apps for everything from parking to bathroom line tracking. NBA arenas have also embraced flashy tech – for instance, some have projection systems that turn the entire court into a screen for pre-game hype animations. That’s something baseball could consider for in-between innings entertainment (imagine the field lit up with a projection mapping show – though the dirt and grass might complicate it). On the entry and ticketing front, all sports are converging on digital tickets and, increasingly, biometric options. What MLB calls Go-Ahead, the NFL (and some NBA) are using CLEAR lanes (fingerprint or iris scan for known travelers, repurposed for stadium entry). By 2025, a number of NFL stadiums and at least a couple of NBA arenas have biometric entry for premium seat holders or fast lanes, similar to MLB’s approach stadiumtechreport.com. The difference is mostly branding and rollout scale. One area where some soccer stadiums, especially in Europe, have gone a bit further is facial recognition for security – e.g., identifying known hooligans or enforcing bans. That’s controversial and not something U.S. leagues admit to doing widely (due to privacy laws and backlash), though as the stadium tech report hinted, some U.S. venues might quietly use such systems for big events stadiumtechreport.com stadiumtechreport.com. Another interesting comparison: climate and sustainability tech. Not explicitly asked, but worth noting: many new stadium innovations revolve around energy efficiency, solar panels, water recycling, etc. MLB’s tech push is very fan- and play-focused, but behind the scenes, ballparks are also getting greener, often borrowing tech used in other large venues. It’s a less sexy topic but part of the modernization.
- Esports and Global Reach: While MLB’s focus is on tech within the game, the NBA and others have capitalized on esports (NBA 2K League, etc.). MLB’s equivalent might be their VR Home Run Derby or partnerships with video game publishers, but it’s not as expansive. In terms of global fan tech, NBA and European soccer have probably done more with localized apps, social media engagement in local languages, etc. MLB is trying with events like the London Series and using technology to stream games at different times for global audiences, plus things like virtual ballpark events that anyone worldwide can join. So tech is a tool for globalization too – e.g., a fan in India can authentically experience a Yankees-Red Sox game in VR without ever traveling, which is huge. NBA was early in streaming games in China on mobile, etc. MLB is catching up, investing in international broadcasting and streaming platforms so that tech can carry baseball beyond its traditional borders.
In summary, MLB stands out for weaving technology into the fabric of the sport while maintaining its character. Other leagues have their own strengths – the NFL in using tech for compelling TV graphics (like the virtual first-down line, which was revolutionary in its time, or now the on-field AR for play diagrams), the NBA for integrating analytics into fast-paced action, and soccer for efficiently using replay without too much disruption (well, depending on who you ask). Baseball’s slower pace has ironically allowed it to implement some of the most advanced tech (you have time to show replays, to digest stats, to challenge calls without missing live action). And because baseball is so stats-driven, fans have embraced many of the changes. A decade ago, purists fretted about things like pitch clocks or too many replays slowing the game, but as Commissioner Manfred observed, the tune is changing – accuracy and engagement are winning out over nostalgia for imperfection foxsports.com.
Each sport is learning from the others: the NFL sees MLB doing ABS challenges and might wonder if a similar system could assist their refs on pass interference calls; MLB saw the success of tennis challenges and was encouraged that fans love that kind of drama. All major leagues convene in sports technology summits and share best practices (for instance, the NHL partnering with Sony (Hawk-Eye’s owner) for puck and player tracking was likely informed by what MLB/NFL/NBA already did hawkeyeinnovations.com hawkeyeinnovations.com). In the end, fans just want the best of both worlds – the thrill of competition and the fairness/insights that tech can provide. In 2025, MLB is delivering exactly that, and often leading the pack.
Recent Updates, Controversies, and Reactions (2024–2025)
The rapid rollout of new tech in MLB hasn’t been without headlines and debates. Here are some of the notable recent developments and how players, coaches, and fans are reacting:
- ABS Challenges in Spring Training 2025: This was big news heading into the season. As noted, the challenge system was used in over 60% of spring games espn.com. Players generally liked the agency of being able to challenge a call they truly believed was wrong. There were some strategic wrinkles – teams pondered when to use a challenge. Do you save it for a high-leverage late inning, or use it early to get a big inning going? Pitchers and catchers had to quickly agree on challenging a call within seconds, which led to some funny moments of indecision. One minor controversy: in one spring game, a young batter clearly went around (swung) on a two-strike pitch but the ump called no swing and ball. The defensive team tried to challenge, but check swings are not challengeable – ABS only covers the pitch location, not swing/no-swing calls (those remain human judgment). This sparked discussion if future systems might also use cameras to judge swings – a tougher problem. Umpires, for their part, publicly said they welcomed any tool that gets calls right (at least the official line), though privately some are wary that this is inching towards replacing their primary function. The league has been careful to frame ABS as “augmenting” umpires, not replacing – for now.
- Pitch Timer and Tech Adjustments: The new pitch clock introduced in 2023 dramatically sped up games, and interestingly it synergizes with tech like PitchCom. By 2024, violations were way down as players adjusted. One thing that came up: pitchers using PitchCom sometimes blamed button lag or complexity for a clock violation (like if they fumble pressing the right pitch, lose a couple seconds). In response, some teams simplified their PitchCom code words to just 3-4 buttons (instead of 9 options) to speed up selection. MLB also tweaked the rules to allow batters to use PitchCom in 2024 (to request timeouts through the device, theoretically), but that’s not really in use – it was an idea floated and shelved.
- Banning In-Game Video and its Reversal: After the 2017-2019 sign-stealing saga (Astros, Red Sox incidents), MLB had restricted in-game access to video (players couldn’t watch at-bats on clubhouse iPads during the game, etc., to prevent abuse). By 2022, with PitchCom mitigating sign-stealing, MLB relaxed those rules, bringing back in-game video tablets but with a short delay and some monitoring. Hitters like J.D. Martinez, who are notorious video studiers, were thrilled. The controversy here was balancing cheating prevention with players’ desire to make adjustments with video. Tech provided a solution via trusted/delayed devices that give useful info without a cheating window.
- Player Concerns Over Biometric Data: A 2024 story raised the issue of who owns the data from wearables. Players were a bit uneasy realizing that teams had a lot of sensitive health info. The MLBPA was reportedly negotiating parameters – for example, data from a WHOOP or Motus sleeve cannot be used as evidence in arbitration (e.g., “you got tired in September, your HRV dropped, so we’re paying you less”). Also, players wanted assurances that data wouldn’t be shared beyond team/internal use. This is an ongoing behind-the-scenes negotiation. So far, no huge public fight, but it’s a tension point. Some players opt out of certain tracking on principle, but they may be in the minority as most see the performance benefits.
- Fan Backlash to Facial Recognition: When MLB’s facial ticketing trial expanded in 2024, it did spark some protests. Privacy advocates outside a few stadiums handed out flyers warning fans of data risks. An ESPN piece captured the split: many fans were “largely unconcerned, if not downright enthusiastic” about breezing through the gate, while a vocal minority was very opposed espn.com espn.com. To assuage fears, MLB has been transparent about deletion policies (they claim the facial tokens are deleted if you withdraw, etc.) and that it’s opt-in. Still, one can foresee a world where paper tickets are gone and some fans feel left behind (e.g., older fans without smartphones). Teams have started having “digital ambassadors” at gates to help less tech-savvy fans get in, but it’s an adjustment. Overall, though, usage of Go-Ahead Entry grew each month in 2024 – by postseason, some parks had dedicated lanes that moved much faster than the norm, which in turn encouraged more to sign up. This is likely to keep expanding in 2025.
- AI Commentary – Hits and Misses: No robot Vin Scully yet, but there was a mild kerfuffle when a regional sports network experimented with an AI-generated narrator for a highlights package due to staff cuts. The result was… not great. Fans mocked the monotone voice and the occasional mispronunciations of player names. It was a reminder that as much as AI can augment, the human touch in storytelling is still cherished. FOX and ESPN reassured viewers they weren’t replacing commentators, just giving them better tools. In fact, the tech is more often used to generate supplementary content (like an AI “analyst” on a website that spits out trivia). So, the worry of AI overtaking broadcast talent has cooled for now – if anything, fans lament some broadcasts becoming too stats-heavy or formulaic, and they actually welcome unique human elements (like when players are mic’d up and joking with announcers on air – a popular feature ESPN and FOX did more of in 2023-25).
- Umpire AI Evaluation: A news item in late 2024 reported that MLB would start publishing umpire accuracy scores after each game (already sites like Umpire Scorecard on Twitter were doing it unofficially using Statcast data). This was somewhat controversial; umps don’t love being publicly graded by a computer for every mistake, fearing it undermines authority. But many fans love the accountability and insight. It also adds pressure in the ABS debate – if an umpire is missing 8% of pitches, the call for robo-umps grows. Expect this tension to continue. Some umps have improved their accuracy thanks to the feedback – rising to the challenge – which is a positive unintended consequence.
- Tech Glitches: Of course, technology isn’t flawless. We’ve seen a few funny or frustrating glitches: a PitchCom failure leading to an awkward pause as the catcher had to run to the dugout for a replacement device (fans chuckled seeing technology literally “call time out”). In one instance, a power outage at a stadium knocked out the Statcast system for a few innings – broadcast graphics had to revert to old-school speeds from radar guns and manually entered info. And during a 2024 game, the replay review system went down briefly, forcing the umps to stick with a call because New York couldn’t see the video – an odd throwback moment. MLB now has backups and redundancies for these systems knowing how crucial they are.
- Players Pushing Back on New Gear: When the pre-tacked ball was tested in Double-A, a few pitchers complained that it felt too different – muscle memory from the old mud-rubbed balls is ingrained, and any change can perturb. Similarly, when MLB introduced slightly bigger bases in 2023 to improve safety and encourage steals, some purists joked it was “inflatobase” and not real baseball, but that died down quickly as the change was fine. If MLB ever tries something like electronic strike zone in the majors, expect initial pushback from certain traditional players or pitchers who built careers around stealing strikes at the edges. For instance, a noted “framer” catcher might lament, as one did anonymously, “There goes one of my skills – I might as well be a DH.” But as older generations retire and new ones who grew up with tech come in, acceptance increases.
- Expert Quotes on the Tech Boom: Many former players and analysts have weighed in. Hall of Famer John Smoltz, now a broadcaster, has been cautiously optimistic – he supports robo-umps for consistency but warns against losing the art of catching. “It’s coming, and it’s good for the game, but I do feel for catchers who spent years honing framing,” he said on air during a 2025 spring broadcast. Players like Max Scherzer have been outspoken too – Scherzer embraced PitchCom (even hacked it to call his own pitches faster) but is more old-school about the strike zone, saying he likes the human element and would prefer umps just improve rather than defer to a machine. In contrast, hitters like Giancarlo Stanton publicly said they’re all for ABS because “a strike should be a strike, period” – reflecting frustration with some umpires’ inconsistencies.
The league itself through Commissioner Manfred often emphasizes balance: “We’re blending technology with tradition to make a better product,” he said at the 2025 owners’ meetings, noting that fan feedback on rule and tech changes has been largely positive (shorter games, more action, fairer calls). One revealing quote: “If our fans are telling us via email that they want a change, we listen” foxsports.com – indicating the league’s awareness of the modern fan’s expectations in a world of high-def replays and zero tolerance for obvious errors.
In the end, the 2024–2025 period in MLB will likely be remembered as a turning point where decades-old debates were resolved by technology. Balls and strikes – settled by ABS. Sign-stealing – thwarted by PitchCom. Slow games – fixed by timers and data aiding pace. And fans – engaged more than ever through digital platforms. There will always be some friction (change is hard in a sport so rooted in history), but the general trend is that once the new tech proves itself, people say “How did we ever live without this?” much like we now can’t imagine baseball without instant replay or without a strike zone graphic on TV.
Conclusion
Baseball’s marriage of tradition and technology in 2025 is an exciting evolution. A sport often dubbed “old-fashioned” is now at the cutting edge: tracking every movement, analyzing every play, and enhancing every fan interaction with sophisticated tech. From the crack of the bat to the turnstile at the stadium, innovation is touching all aspects of MLB. And yet, the essence of the game – the duel between pitcher and batter, the strategy, the summer pastime joy – remains intact, perhaps even heightened by the insights and fairness new technology brings.
As MLB continues to innovate, it balances on a fascinating tightrope: leveraging the latest science and engineering to improve the sport, while preserving the human drama and unpredictability that make baseball, baseball. Other leagues are watching closely, and in many cases, emulating MLB’s tech-forward moves. The 2025 season and beyond will no doubt bring further advances – maybe the first robot ump in a regular season game, or a full AR broadcast where fans can place themselves virtually on the mound. What’s clear is that Major League Baseball has fully entered a high-tech era, embracing it in ways that enrich the game for players and fans alike. The old ballgame has learned some remarkable new tricks, and it’s winning over a new generation while rekindling the love with long-time fans who are seeing the sport in an illuminating new light. As one technology columnist aptly put it, “Baseball is coding its future, one pitch at a time.” And so far, the results are a grand slam for the sport. hawkeyeinnovations.com foxsports.com
