A computerized system for calling balls and strikes is undergoing testing during Major League Baseball spring training exhibition games, following four years of trials in the minor leagues. The Automated Ball-Strike System (ABS) is supported by Baseball Commissioner Rob Manfred and could potentially assist MLB home plate umpires as early as 2026 without replacing them.
The ABS technology involves outfitting stadiums with cameras that track each pitch to determine if it crosses home plate within the strike zone. Umpires wear ear buds to receive 'ball' or 'strike' calls, which are then relayed to players and fans using traditional hand signals.
