July 9, 2025
Major League Baseball plans to use its robot umpire technology for ball-strike challenges in Tuesday’s All-Star Game at Atlanta, another step toward possible regular-season use next season. MLB says it intends to make the All-Star announcement Thursday. Teams won 52.2% of their ball/strike challenges during the spring training test, with 617 of 1,182 challenges successful in the 288 exhibition games using the Automated Ball-Strike System. ABS was installed at 13 spring training ballparks hosting 19 teams, and an animation of the pitch was shown on video boards showing spectators the challenge result.
