Overview
- Statcast’s Spring Training sample shows 53% of ABS challenges overturned (242 of 457), with pitchers and catchers winning 56% and hitters at 49%.
- Usage varies widely by club, with the Yankees logging 14 reviews so far and the Marlins just one, reflecting divergent early approaches.
- Notable moments include five straight overturned calls on one plate umpire and an ABS ruling that a called strike missed the zone by under a tenth of an inch.
- Under MLB’s rules, only the batter, pitcher or catcher may challenge within seconds of a call, teams start with two challenges, and successful reviews are retained.
- Player reactions remain mixed, highlighted by a Yankees reliever losing a clear-cut challenge, a Jack Flaherty–Dylan Campbell exchange after an upheld strike, and some veterans choosing to avoid the system.
