Major League Baseball is unlikely to implement robot umpires for the 2024 season, says Rob Manfred.

The automatic ball-strike system (ABS) is currently being used in Triple-A.

"I think there's some sentiment among the group that we made had a lot of changes here," Manfred said. "We ought to let the dust settle, and there are clearly unresolved operational issues with respect to ABS. Despite all the testing, we still have some things that are unresolved."

Defining a computerized strike zone is among the issues.
