Data from taptochallenge.com, summarized by The Athletic’s Johnny Flores Jr., shows catchers have challenged 90 calls, compared with 78 by batters and five by pitchers. Notably, Edgar Quero of the Chicago White Sox leads with seven challenges (four won), followed by players such as Salvador Perez (Royals), Patrick Bailey (Giants), Cal Raleigh (Mariners) and Will Smith (Dodgers) who are tied for second with four apiece. Perez, boasting a perfect 4-for-4 success rate against the Braves on March 27, has already demonstrated the system’s potential to translate challenged calls into strikes.
The ABS debut has also produced early manager-related incidents, including ejections tied to decision-making under the new rules. Boston’s Alex Cora was ejected after arguing with umpire C.B. Bucknor over a check-swing call, while Minnesota’s Derek Shelton was also ejected after a sequence involving a closer and a perceived timing issue with a pitcher’s hat tap. These episodes underscore the growing influence of ABS on game management and the evolving relationship between managers, umpires, and players as everyone adapts to the new system.
Overall, the quick adaptation to ABS—by catchers and managers alike—could offer a competitive edge in 2026 as teams refine their approach to challenges and strike-zone interpretation. With continued data from early-season games, the league can better gauge how ABS will influence outcomes, challenge efficiency, and strategic decision-making across the sport.
