MLB’s ABS Challenge System is exposing the worst umpire in baseball | The Verge

This page discusses how MLB's new Automated Ball-Strike (ABS) Challenge System is exposing the poor umpiring of CB Bucknor. Introduced this season, the ABS allows players to challenge strike and ball calls for the first time. During Saturday's Red Sox-Reds game, Eugenio Suarez successfully challenged two consecutive strike-three calls against Bucknor, with both overturned by the robot umpire. The successful challenges generated louder cheers than the team's two home runs. Bucknor had multiple calls reversed that night. The week culminated when he was struck in the mask by a foul ball during Wednesday's Rays-Brewers game and had to leave the field.
