Automated Ball-Strike System Overturns Strike Two Call in MLB Game
A strike two call was overturned in a Major League Baseball game after an Automated Ball-Strike System (ABS) challenge.

Kansas City, MO, September 13, 2026 — In a recent Major League Baseball game, a crucial call regarding a strike two was overturned following the use of the Automated Ball-Strike System (ABS). This instance highlights the evolving role of technology in officiating professional baseball and its potential impact on game outcomes.
The Automated Ball-Strike System, designed to provide greater accuracy in determining balls and strikes, was engaged when a player or coach challenged an umpire’s strike two call. Following the challenge, the ABS reviewed the pitch, and the system’s data led to the original call being overturned. The specific details of the game, including the teams involved, the date, the location, and the inning in which this event occurred, were not provided in the information available.
The ABS technology aims to reduce human error in one of baseball’s most frequently made calls. It utilizes a series of cameras and tracking technology to determine the precise trajectory and location of pitches in relation to the strike zone. This data is then relayed to umpires, who can use it to make or correct calls.
The implementation and use of such systems in professional sports leagues are part of a broader trend toward integrating advanced technology into officiating. While the system’s aim is to ensure fairness and consistency, its application can also lead to moments where human judgment is superseded by algorithmic evaluation. The specific outcome of the game following this overturned call was not detailed.
The league’s adoption of the ABS allows for challenges on ball and strike calls, giving teams an additional mechanism to contest decisions they believe are incorrect. The process involves specific protocols for initiating a challenge, which then triggers an automated review. The outcome of this particular challenge resulted in the strike two call being reversed, indicating the system’s active role in influencing the game’s progression.
