Major League Baseball will use the automated ball-strike challenge system (ABS) during next week’s All-Star Game in Atlanta.
The decision comes after the league revealed that it could begin using ABS on a full-time basis starting in 2026.
In this year’s All-Star Game, umpires will call balls and strikes. However, each team will be given two challenges via ABS; successful challenges are retained. Only pitchers, catchers, and hitters can ask for challenges.
