Controversial Called Strike Ends Dominican WBC Hopes as U.S. Advances to Championship Game

A split-second call in Miami extinguished the Dominican Republic’s World Baseball Classic ambitions Sunday night, delivering a 2-1 victory to the United States and sending the Americans to the championship game against Venezuela or Italy. Plate umpire Cory Blaser’s strike-three ruling on a full-count slider to Arizona Diamondbacks infielder Geraldo Perdomo—seen by many as low—sparked immediate outrage and underscored the high-stakes transition MLB is preparing for. Just 10 days before Opening Day, the game became an unintended flashpoint for the league’s coming Automated Ball-Strike Challenge System, which will debut March 25 and could reshape how baseball’s most contentious calls are made.

The Controversial Call That Changed the World Baseball Classic

With the Dominican Republic trailing by one run in the bottom of the ninth inning, Geraldo Perdomo watched Mason Miller’s 98-mph slider tail just under the traditional strike zone. Believing the pitch was ball four, Perdomo began trotting toward the dugout before Blaser’s emphatic strike-three signal froze the game in place. The call stranded the tying run at third and preserved the U.S. lead, ending the Dominican rally and sparking immediate controversy.

Perdomo and Teammates Question the Call

Perdom, visibly stunned, nearly swung his bat overhead in disbelief before catching himself. ‘He knew he was wrong,’ Perdomo told reporters afterward. ‘I knew it was 100% wrong.’ Teammates echoed his sentiment, with Arizona Diamondbacks outfielder Alek Thomas remarking, ‘That pitch looked like a ball to everyone in the dugout.’ The frustration mirrored the broader skepticism surrounding umpire consistency—a core justification for MLB’s push toward automated strike systems.

Miller’s dominance was undeniable: He struck out Perdomo on a slider after working the count full, following 13 of his 22 pitches at 100 mph or higher. The Dominican rally had begun with a one-out walk to Seattle Mariners star Julio Rodríguez, who advanced to third on a wild pitch and Oneil Cruz’s groundout before the decisive at-bat.

How Human Umpiring vs. ABS Would Have Changed the Outcome

Had the World Baseball Classic already implemented MLB’s Automated Ball-Strike Challenge (ABS)—a system testing the use of robot umpires since 2019—the Dominican Republic could have contested Blaser’s call. Under current ABS rules, a pitch must cross the entire ‘virtual’ strike zone, a three-dimensional box spanning the width of the plate from the hollow below the kneecap to the midpoint between the batter’s shoulders and belt. The slider Miller threw appeared to fall just below this threshold, meaning an automated system would have ruled it a ball.

‘I can understand why Dominicans are upset about it. That ball had a lot of plate, and Will does a hell of a job in framing, but yeah, I’m in favor of ABS coming into the game.’ — U.S. manager Mark DeRosa, referencing Dodgers catcher Will Smith’s pitch-framing abilities

DeRosa’s remarks highlighted the duality of the moment: Human umpires’ reliance on pitch-framing—where catchers subtly move pitches into the strike zone—versus the ABS’s objective, data-driven approach. Smith’s framing likely influenced Blaser’s call, a factor DeRosa acknowledged even as he supported the eventual adoption of ABS.

Why the Called Strike Matters Beyond the Game

The Dominican Republic’s near-miss in Miami isn’t just a footnote in baseball history; it’s a preview of the seismic shifts coming to MLB. The league’s Automated Ball-Strike Challenge System, slated for full implementation in 2026 after minor-league trials began in 2019, will debut in a limited capacity when the regular season begins March 25. The technology—developed in partnership with Hawk-Eye Innovations—uses high-speed cameras and AI to track pitch trajectories in real time, eliminating human error in balls and strikes.

The Science Behind ABS: How Robot Umpires Work

The ABS system relies on a network of six high-definition cameras positioned around the stadium to triangulate the flight path of every pitch. Within 300 milliseconds of release, the system calculates the pitch’s trajectory and determines whether it passes through the strike zone as defined by MLB’s rulebook. Umpires retain authority to override the system in cases of equipment malfunction or obstruction, but the technology aims to standardize a call that has historically been among baseball’s most inconsistent and debated.

MLB’s decision to phase in ABS follows decades of frustration over umpire errors. A 2022 study by the *MIT Sloan Sports Analytics Conference* found that umpires missed calls on approximately 12% of pitches during the 2021 season, with high-leverage situations like full counts seeing even higher error rates. The Dominican Republic’s loss in Miami served as a real-world example of how a single, contentious call can alter the trajectory of a tournament—or a team’s season.

The Human Element: Why Some Players and Coaches Resist ABS

Not everyone is embracing the robot umpire era. U.S. outfielder Pete Crow-Armstrong, who played in the game, expressed relief that the human element was still in play. ‘I’m happy that the human element was in full effect,’ he told reporters. ‘It looked a little down, yes, but we didn’t lose the game there.’ His sentiment reflected the broader skepticism among veteran players and coaches who argue that baseball’s charm lies in its imperfections, including the occasional controversial umpire’s call.

Dominican manager Albert Pujols, a 10-time All-Star and former MVP, downplayed the controversy, stating, ‘I don’t want to focus on the last pitch. I’m disappointed about the way that the game ends, but I don’t want to criticize any of that. It just wasn’t meant to be for us.’ Pujols’s graciousness belied the frustration felt by many in the Dominican camp, where the loss stung not just for the outcome but for the manner in which it was decided.

The Broader Implications for Baseball’s Future

The World Baseball Classic loss in Miami was more than a semifinal defeat; it was a microcosm of the debates roiling MLB as it prepares for a technological overhaul. The league’s shift toward data-driven officiating reflects broader trends in sports, from the NFL’s use of instant replay to the NBA’s semi-automated officiating system for out-of-bounds calls. Yet baseball’s tradition-bound culture makes the transition uniquely fraught, with purists arguing that the human element is intrinsic to the game’s identity.

Will ABS Eliminate Controversy—or Create New Ones?

Proponents of ABS argue that the system will reduce bias, inconsistency, and the influence of pitch-framing—a skill that has historically rewarded catchers who subtly manipulate umpires’ perception of the zone. Critics, however, warn that robot umpires may introduce new forms of controversy, such as disputes over the system’s accuracy or the rigidity of its strike-zone definitions. For example, the ABS’s virtual zone does not account for a batter’s stance or swing path, which human umpires often consider when making calls.

MLB has acknowledged these concerns, incorporating a ‘challenge’ system in the minor leagues where managers can contest up to two calls per game. The rule is expected to evolve in the major leagues, with potential expansions to the number of challenges or the introduction of a ‘review’ system for replay-based adjustments. Yet even with these safeguards, the league faces the challenge of maintaining fan trust in a system that, by design, removes the human element from one of baseball’s most iconic decisions.

The Road Ahead: ABS in the 2024 World Baseball Classic and Beyond

While ABS will not be used in the 2024 World Baseball Classic—a decision made to preserve the tournament’s traditional format—the controversy in Miami served as an early warning of the debates to come. MLB officials have hinted that robot umpires could be tested in future WBC editions, particularly as the league continues to refine the technology. For now, the focus remains on the 2024 regular season, where ABS will debut in a limited capacity before full implementation in 2026.

The Dominican Republic’s loss in Miami may have been painful, but it also provided a glimpse into baseball’s future. As the league marches toward an automated officiating era, the question isn’t whether technology will change the game, but how the sport will adapt to a world where even the most iconic calls are no longer made by human eyes.
