Team USA’s 2-1 WBC semifinal victory over the Dominican Republic is being completely overshadowed by umpire Cory Blaser’s two historically bad strike calls—including a game-ending slider that landed a full foot outside the zone—reviving the urgent debate over implementing the Automated Ball-Strike (ABS) system in international baseball.
The World Baseball Classic semifinal between Team USA and Dominican Republic will be remembered not for its clutch hitting or dramatic pitching, but for one umpire’s failure. With the tying run on third base in the bottom of the ninth, home plate umpire Cory Blaser called a slider from Mason Miller that was clearly outside the strike zone a strike three, ending the game and igniting a firestorm of criticism as reported by the New York Post.
Geraldo Perdomo, the Dominican Republic’s shortstop, reacted with stunned disbelief, throwing his hands in the air as the game ended. The pitch was so far from the zone that both the Fox Sports broadcast crew and MLB’s Statcast data immediately confirmed it was a ball, not a strike. The absence of the Automated Ball-Strike (ABS) challenge system—standard in MLB playoffs but not used in the WBC—meant there was no mechanism to correct the clear error.
“That slider right there that was below the zone. And, one team reacting. The other just stunned,” former major league pitcher John Smoltz said on the Fox broadcast after reviewing the replay, his analysis confirming what every viewer saw according to the New York Post. Play-by-play man Joe Davis added, “Thinking, ‘You sure we don’t have ABS yet? You sure we can’t challenge that?’ Perdomo and the Dominican Republic are wondering, and they’ll have to wonder what would have happened with Fernando Tatis Jr. left standing on deck.”
The controversy wasn’t isolated to the final pitch. Earlier in the eighth inning, with the Dominican Republic’s Juan Soto at the plate, Blaser called another third strike on a pitch that Statcast data showed was also out of the zone. That call took a potential rally off the board for a Dominican team that had already overcome an early 1-0 deficit.
The aftermath brought immediate and severe criticism from baseball’s biggest names. On the Fox postgame show, Alex Rodriguez stated plainly: “You just hate to end a game this big with these types of consequences on a pitch that’s not a strike.” teammate Derek Jeter went further, predicting a systemic change: “Well, you can pretty much guarantee they’re going to have the (ABS) challenge system in place for the next WBC, right?”
This incident resurrects a core debate about technology in baseball. The WBC, a tournament designed to showcase the global game, has opted to use traditional umpiring, creating a disconnect with MLB’s playoff environment where ABS challenges are standard. For the Dominican Republic, whose roster featured stars like Tatis Jr. and Soto, the loss feels especially cruel given the technological tools available that were deliberately withheld. The absence of replay on balls and strikes means the tournament’s integrity is perpetually vulnerable to human error in high-leverage moments.
Team USA’s path to the final was forged by offensive sparks in the fourth inning. After the Dominican Republic took an early 1-0 lead, Gunnar Henderson launched a solo home run to tie the game. Two batters later, Roman Anthony followed with his own solo shot, giving the USA a 2-1 lead that would hold—thanks in part to the pitching of Mason Miller and, ultimately, a devastatingly incorrect call by Blaser.
The scheduled championship game on Tuesday will feature Team USA against the winner of Monday’s contest between Italy and Venezuela. But the narrative dominating the baseball world has already shifted from the upcoming final to the officiating failure that decided this semifinal. Social media and sports shows are awash with the video of Perdomo’s strikeout, the Statcast box illustrating the pitch’s location, and the repeated question: how could a tournament of this caliber still lack a system to fix clear errors?
For fans of the sport, this moment crystallizes theargument for technology. The WBC has always balanced tradition with spectacle, but allowing a game—and a nation’s World Cup dreams—to be ended by a pitch that was demonstrably not a strike is an unacceptable failure of the event’s administration. The pressure will now be immense on WBC organizers to implement ABS challenges before the 2029 tournament.
The Dominican Republic’s exit is a heartbreaking end to a dominant run through the pool play, while Team USA advances with a victory marred by an asterisk that will follow it into the championship game and beyond. Baseball’s human element has always been part of its charm, but there is a line between human error and裁判 incompetence that cost a team a chance at the title. That line was crossed last night at loanDepot park, and the sport’s leadership must respond.
