The Cincinnati Reds enjoyed a celebratory atmosphere after defeating the Chicago Cubs 10-8 on Friday, marking a significant win. The Cubs, however, faced disappointment as their bullpen struggled to contain the Reds’ late-inning efforts.
Postgame discussions largely focused on the performance of home plate umpire Bill Miller, who will likely want to forget this game. Miller went 0-for-8 on challenges involving the automated ball-strike system (ABS), with all his calls being overturned. The Cubs won five challenges, while the Reds secured the other three.
The Impact of ABS Challenges
The first overturned call occurred early in the game when Miller initially ruled a fastball by Reds pitcher Rhett Lowder a ball. An ABS challenge proved the pitch was within the strike zone.
From there, Miller’s night continued with challenges and overturns. Chicago catcher Carson Kelly challenged four calls successfully, and Reds star Jose Trevino won two challenges. Sal Stewart from the Reds and Seiya Suzuki from the Cubs each succeeded with one challenge.
Notably, Reds catcher Tyler Stephenson did not raise any challenges that night, despite leading the league with 88 successful challenge overturns out of 124 attempts.
Previous ABS Disputes and Reactions
Bill Miller has been involved in ABS disputes before, especially during Reds games. Last month, Reds infielder Edwin Arroyo collided with Miller while fielding a ground ball, impacting the Reds’ ability to close the inning.
Cincinnati reliever Caleb Ferguson expressed frustration with Miller’s role in that incident, leading to a heated moment picked up by television cameras. Ferguson later apologized for his actions, acknowledging his behavior as unprofessional.
Tracking ABS Performance
Data from TapToChallenge.com reveals that Miller’s performance in Chicago, with eight overturned calls, is among the worst since MLB implemented the ABS challenge system in 2026. Miller ranks ninth among umpires for overturned calls, with others like Hunter Wendelstedt and Dan Iassogna leading the league.
Chantz Martin, a sports writer for Fox News Digital, noted the ongoing evolution and public interest in the role of ABS challenges in baseball.
