Hitters are winning more ABS challenges in the postseason, and teams are challenging more overall

Batters are achieving higher success rates on robot umpire challenges in the postseason compared to the regular season, while teams are employing the Automated Ball-Strike System (ABS) more frequently in the playoffs. In the 25 games of the Wild Card Series and Division Series, 71 of 121 overall challenges under ABS were successful, marking a 3% increase from the regular season's 54%.

The batters' success rate improved to 57% (29 of 51) from 49%, and their challenge frequency rose to 2.04 per game from 1.96. Teams exhaust their challenges when unsuccessful twice in a game, so the more wins, the more opportunities for additional challenges. Catchers won 60% (42 of 70) of challenges, slightly above their 59% in the regular season, while pitchers were unsuccessful in both attempts.

Despite this, managers remain cautious about using ABS due to its novelty and potential impacts on game dynamics. Notable performers included Milwaukee's Jake Bauers and Atlanta's Austin Riley, who won both their challenges, while Atlanta's Ronald Acuña Jr. had the most overall attempts, with a 50% success rate.
