It didn't take long for the ABS system to prove human umpires wrong during MLB's first spring training game of 2025.

The Automated Ball-Strike system, or ABS system, which was tested at the Triple-A level during the 2023 and '24 seasons, is slated to be featured in roughly 60% of games this spring. As clubs begin training for game action with live batting practice sessions, the ABS system is being previewed for hitters and pitchers.

MLB players can challenge ball and strike calls. The camera-based system is only an experiment for now — but it has the baseball world wondering where to draw the line with technology.
