Home plate umpire Bill Miller made history Friday at Wrigley Field—but not the kind worth celebrating. Every single ball-strike call he made during the Cincinnati Reds' 10-8 victory over the Chicago Cubs was overturned upon automated review. All eight of them.
Miller's perfect storm of errors represents what appears to be the worst performance by any umpire since MLB introduced the automated ball-strike challenge system at the start of the 2026 season, according to data from TapToChallenge.com.
Four pitches were successfully challenged by Cubs catcher Carson Kelly. Reds catcher Jose Trevino won challenges on two calls. Two additional reversals came from the batter's box—one by Reds infielder Sal Stewart, another by Cubs outfielder Seiya Suzuki. Of the eight disputed pitches, only two were initially ruled strikes. The rest were called balls, then proven to be strikes by the automated system.
This wasn't Miller's first brush with controversy. Last month during another Cincinnati game, Reds reliever Caleb Ferguson unleashed an expletive-laden tirade at Miller after an infield collision with Reds infielder Edwin Arroyo appeared to affect the play. Ferguson later apologized, calling his outburst "unprofessional."
According to league statistics, Miller's 70 overturned calls rank ninth among MLB umpires. But his Friday performance—a complete shutout in the challenge department—raises questions about his consistency and whether mid-pack rankings mask chronic accuracy problems that surface under certain conditions.
The automated challenge system has created unprecedented transparency in baseball. For the first time in the sport's history, every close call is subject to objective verification. That transparency is catching umpires making errors at rates that suggest either inadequate training, insufficient accountability, or both.
Hunter Wendelstedt leads all umpires in overturned calls, followed by Dan Iassogna, Malachi Moore, Lance Barrett and Manny Gonzalez. The disparities raise questions MLB has yet to address publicly: Why are some umpires systematically making more errors than others? What differentiates high-accuracy from low-accuracy officials? And what happens to umpires who consistently rank at the bottom?
In any other profession, an employee posting Miller's accuracy metrics would face remedial training, performance review or disciplinary action. Yet MLB's response to umpire performance data has traditionally been opaque.
The automated challenge system was ostensibly introduced to improve accuracy and reduce human error in critical moments. What it's actually doing is creating a public record of umpire performance that never existed before. That transparency is uncomfortable for the league, which has historically operated under a code of deference to umpires rooted in baseball tradition rather than professional standards.
But Friday's game demonstrates that deference may no longer be sustainable. When an umpire goes 0-for-8 on objectively verifiable calls, the conversation can't remain behind closed doors. Players notice. Teams adjust. Fans watch the replays and lose faith in the integrity of live play.
Moving forward, MLB faces a choice: continue treating these newly transparent performance metrics as incidental data points requiring no systematic response, or acknowledge them as evidence that some umpires require intervention, retraining or potentially removal from high-pressure situations until their accuracy improves.
Miller's 0-for-8 night has become part of baseball's permanent record in an age of automated accountability. The only question is whether MLB will finally act on what that record reveals.
