Major League Baseball's new Automated Ball-Strike (ABS) system made its mark in a high-stakes moment during a game between the Boston Red Sox and Cincinnati Reds. Umpire C.B. Bucknor incorrectly called two consecutive strikeouts against Reds hitter Eugenio Suarez, but both calls were overturned after challenges. The ABS system, introduced in the 2026 season, allows teams two challenges per game to verify umpire calls using high-speed cameras and a digital strike zone.
The incident occurred in the bottom of the sixth inning with the bases loaded and two outs. Bucknor called a third strike on Suarez, prompting a challenge. The ABS system confirmed the pitch was outside the strike zone, allowing Suarez to continue his at-bat. On the next pitch, Bucknor again called a strikeout, but another challenge revealed the call was incorrect. The Reds crowd erupted as the system overturned the call for the second time in under two minutes.
The ABS system, a hybrid of human umpires and technology, uses a network of high-speed cameras to track pitches in three dimensions. It compares the pitch's location to a batter-specific digital strike zone, providing near-instant feedback. Teams have two challenges per game, which reset if used correctly. The system aims to reduce human error while maintaining the umpire's role in managing the game.
Fans and analysts have praised the ABS system for its accuracy and transparency. The technology has been well-received, with early games showing its potential to correct errors in real time. However, some traditionalists argue that the system disrupts the flow of the game and removes the human element of umpiring.
The ABS system is part of MLB's broader push to integrate technology into baseball. While challenges are limited, the league has indicated it may expand the system in future seasons based on feedback and performance.
