A Defector column argues MLB’s automated ball-strike challenge (ABS) could become entertaining theater, emphasizing its quick ~15 second resolution and limited impact on game length, while also wondering how teams and players will actually deploy and respond to challenges.
Major League Baseball is deploying the Automated Ball-Strike System (ABS) this season, using 12 Hawk-Eye cameras to judge pitches and allow teams two challenges per game (one additional in extra innings). A strike under ABS is defined by a height-based zone different from the traditional rule-book box, with calls potentially overturned on challenge success. Spring training data shows varying challenge success by teams and players, highlighting a push for greater accuracy but sparking concerns about humiliation for human umpires and the broader impact on the game. The ABS builds on a two-decade history of electronic umpire evaluation, aiming to correct egregiously missed pitches while leaving room for human judgment on near-calls.
A Sports Illustrated opinion argues that while the NCAA's challenge system has largely succeeded, a controversial kicked-ball non-review in Iowa State’s win over Houston shows how narrow the current rules are; the author urges expanding reviews to every whistle—fouls, travels, kicks, backcourt violations, and more—while preserving limited challenges to curb delays and improve accuracy in games and the tournament.
Aaron Boone expressed cautious optimism about MLB's adoption of the Automated Ball-Strike challenge system, despite his previous reservations, noting it could impact Yankees' strengths in catcher framing and strategic challenges during games.
Major League Baseball has approved the use of robot umpires with an automated ball/strike challenge system starting in 2026, allowing teams to challenge calls and potentially reduce ejections, while human umpires will still call pitches with digital reviews displayed on screens.
Starting in 2026, MLB players will be able to challenge balls and strikes calls using an automated system called ABS, after successful testing in minor leagues and spring training, aiming to improve call accuracy while maintaining game pace.
Major League Baseball has approved the implementation of robot umpires for balls and strikes starting in the 2026 season, using an automated challenge system tested in minor leagues and spring training, aiming to improve accuracy and reduce ejections, while maintaining some human umpire involvement.
MLB Commissioner Rob Manfred discussed the future implementation of an automatic ball-strike (ABS) system, indicating a likely preference for a challenge system over full automation. This system would allow teams to challenge umpire calls using ABS technology. However, due to technical issues, it is unlikely to be ready by 2025. Manfred emphasized the importance of getting the system right and acknowledged concerns about how it might affect the role of catchers and the overall feel of the game.
