Robot umpires are getting called up to the big leagues next season.

Major League Baseball's I-man competition committee on Tuesday approved use of the Automated Ball/ Strike System in the major leagues in 2026.

Human plate umpires will still call balls and strikes, but teams can challenge two calls per game and get additional appeals in extra innings. Challenges must be made bya pitcher, catcher or batter—signaled by tapping their helmet or cap — anda team retains its challenge if successful. Reviews will be shown as digital graphics on outfield videoboards.

Adding the robot umpsis likely to cut down on ejections. MLB said 61.5% of ejections among players, managers and coaches last year were related to balls and strikes, as were 60.3% this season through Sunday. The figures include ejections for derogatory comments, throwing equipment while protesting calls and inappropriate conduct.

Big league umpires call roughly 94% of pitches correctly, according to Ump-Scorecards.
