The Abs Challenge System Is Exposing The Worst Umpire In Baseball

During Wednesday’s crippled betwixt nan Tampa Bay Rays and nan Milwaukee Brewers, umpire CB Bucknor took a foul shot to nan mask and had to beryllium helped disconnected nan field. It was nan headdress to what has been a peculiarly bad week for 1 of nan astir controversial umpires successful baseball.

It started pinch possibly nan champion illustration of really MLB’s Automated Ball-Strike (ABS) Challenge System tin inject play successful baseball. This is nan first twelvemonth for nan caller robot umpire, which allows hitters, catchers, and pitchers to challenge balls and strikes for nan first time. Each squad starts a crippled pinch 2 challenges. But they only suffer a situation if it’s unsuccessful, truthful players aren’t inclined to request a reappraisal unless they’re sure.

During Saturday’s crippled betwixt nan Red Sox and nan Reds, Eugenio Suarez challenged Bucknor connected back-to-back onslaught 3 calls and successfully had them overturned by nan robo ump.

It doesn’t matter that Suarez yet grounded out. What matters is that, successful a crippled wherever nan Reds deed 2 location runs, nan loudest cheers came for a brace of successful ABS challenges.

This was acold from nan only clip that Bucknor had his calls overturned astatine nan plate, it was a bad nighttime for him overall. There were 8 ABS challenges complete nan people of nan game, and six of them were successful. The 2 calls that were not overturned were highly close, wrong 0.1 inch of nan onslaught area edge. His misses, however, were much dramatic. Three pitches he called strikes missed by 2.4 inches aliases more — 1 was a afloat 2.7 inches retired of nan zone. And, by Jomboy Media’s judgment, Bucknor blew 20 calls if you count ones that weren’t challenged.

As nan crippled progressed, you could spot nan exasperation connected Bucknor’s look turn arsenic nan past 5 challenges were successful. The clear connection from nan robots was: you’re bad astatine your job. The convention complaint for ABS challenges is 55 percent overturns, but Bucknor’s rate stands astatine 78 percent arsenic of April 2nd.

There were a mates of umpires whose first brushes pinch ABS went worse. Chad Whitson had each 7 of nan 7 challenges successful his crippled betwixt nan Yankees and nan Giants connected March 28th overturned. But while Whitson whitethorn person had a bad game, Bucknor has had a unsmooth career.

According to measurements by UmpScorecards Bucknor has been nan slightest meticulous umpire successful Major League Baseball complete nan past 5 years by a important margin. The tract gives each ump an expected accuracy people and past measures really galore correct calls supra aliases beneath that they make. From 2020 done April 2nd of 2026, CB Bucknor is rated arsenic being 253.74 beneath his expected number of correct calls — and his expected accuracy is not peculiarly precocious to statesman with. Bucknor’s closest competitor is nan astir arsenic derided Laz Diaz, who is rated arsenic being 202.03 beneath nan expected number of correct calls complete an adjacent number of games.

Bucknor doesn’t request ABS to make him look bad, either. On Tuesday, he made what is intelligibly the worst call of nan young 2026 play truthful far. He called Milwaukee’s Jake Bauers retired for failing to touch first guidelines connected a groundball. The telephone was quickly overturned connected review, but you didn’t request instant replay to cognize that Bucknor was wrong. The only measurement it could person been much evident is if Bauers stopped and jumped up and down connected nan container pinch 2 feet. The telephone was truthful egregious that some managers exchanged a knowing laughter from crossed nan field.

Teams will evidently person to set to nan caller situation strategy and create strategies for really champion to navigate it. But its biggest effect will beryllium connected umpires who are going to person to set to a much accordant and mathematical onslaught zone. Umpires for illustration CB Bucknor who person had, let’s opportunity a much subjective position of nan strikezone, are going to person a unsmooth 2026.
