Overview

• MLB used the Automated Balls and Strikes system during July’s All-Star Game in Atlanta as a final on-field trial ahead of an expected introduction in the 2026 season.
• MLBPA Executive Director Tony Clark urged adoption of a buffer zone to prevent marginal pitches from being overturned.
• Commissioner Rob Manfred said current technology cannot support a buffer zone and plans to implement the system without one.
• Minnesota Twins outfielder Byron Buxton criticized the system’s complexity and warned it could fuel social media backlash against players.
• The current challenge format allows each team two challenges per game and limits eligible challengers to the pitcher, catcher or batter.
