The ABS Challenge System is exposing the worst umpire in baseball

"During Saturday's game between the Red Sox and the Reds, Eugenio Suarez challenged Bucknor on back-to-back strike three calls and successfully had them overturned by the robo ump. It doesn't matter that Suarez ultimately grounded out. What matters is that, in a game where the Reds hit two home runs, the loudest cheers came for a pair of successful ABS challenges."

"There were eight ABS challenges over the course of the game, and six of them were successful. His misses, however, were more dramatic. Three pitches he called strikes missed by 2.4 inches or more - one was a full 2.7 inches out of the zone."

"As the game progressed, you could see the exasperation on Bucknor's face grow as the last five challenges were successful. The clear message from the robots was: you're bad at your job."

CB Bucknor, a controversial umpire, had a challenging week highlighted by a game where he took a foul ball to the mask. The introduction of the Automated Ball-Strike Challenge System allowed players to successfully challenge his calls, with six out of eight challenges overturned. Bucknor's performance was notably poor, with three missed calls exceeding 2.4 inches outside the strike zone. His overturn rate of 78 percent starkly contrasts with the league average of 55 percent, indicating a significant struggle with accuracy in officiating.
