According to latest reports, MLB is set to introduce the groundbreaking ABS challenge system in the upcoming 2026 season, allowing players to challenge balls and strikes which they believe have been called incorrectly by umpires.
Insider Jeff Passan broke the news about MLB's plan to implement the technology via X on Tuesday.
"Major League Baseball will implement a challenge system for balls and strikes in the 2026 season after the league’s competition committee voted to usher in the era of robot umpiring. Teams will receive two challenges to dispute calls by the home-plate umpire." Passan posted

Reacting to Passan's post, several fans made jokes at the expense of several MLB superstars, imagining hilarious scenarios that could be possible after the introduction of the challenge system.
"Bryce Harper about to punch a robot for arguing balls and strikes. 😂" a fan commented
"Jazz Chisholm will be thrown out at least once for arguing with a robot" another fan wrote
"Judge hitting .400 confirmed with a .600 OBP" another fan replied
"Good. Aaron Boone is going to have to challenge Aaron Judge ABs 2X 162=324 times." another fan responded
"Spencer Jones is gonna use them all up in his first AB and still strike out every game" another fan shared
"YES!! Cal “behind” the dish will be epic!" another fan posted
MLB Comissioner Rob Manfred speaks about desire to "make the game better" with introduction of ABS challenge system
On Tuesday, MLB Comissioner Rob Manfred had his say on the upcoming introduction of the ABS challenge system. As insider Mike Axisa of CBS reported, Manfred spoke about his desire to "make the game better" with the important change.
"We used the same [testing] process with ABS that started with listening to fans, conducting extensive testing at the minor league level, and trying at every step to make the game better. Throughout this process we have worked on deploying the system in a way that's acceptable to players. The strong preference from players for the Challenge format over using the technology to call every pitch was a key factor in determining the system we are announcing today."
"I commend the Joint Competition Committee for striking the right balance of preserving the integral role of the umpire in the game with the ability to correct a missed call in a high-leverage situation, all while preserving the pace and rhythm of the game. I thank the Major League Umpires for their collaboration and the Major League Players for their feedback in moving the game forward for the fans," Manfred said

In 2026, the ABS challenge system will be used in every single official game, including spring training, regular season and the playoffs.
