MLB to test robot umpire tech for checked swings in Triple-A

Major League Baseball is continuing to turn the minor leagues into a live testing ground for the future of officiating and game management. Its latest move is to expand robot-assisted umpire testing for checked swings from Class A to Triple-A, bringing a higher-profile environment to one of baseball’s most subjective calls. MLB is also testing a slightly repositioned second base, stricter limits on pitcher disengagements, tighter controls around batter timeouts, and new rules for pitch clock resets linked to PitchCom issues.

The bigger picture is clear: MLB is not just refining pace-of-play, it is steadily building a framework for more standardised decision-making. Checked swings have long sat in the grey area between human feel and rules-based enforcement, so moving that trial up the ladder is a meaningful step. For leagues and rights holders, that matters because every improvement in consistency strengthens broadcast confidence, betting integrity, and fan trust. Whether all of these changes reach the majors is another question, but the direction of travel is obvious. Baseball is using technology and controlled experimentation to reduce friction around the game’s most debatable moments and modernise the product without changing its core identity.
