MLB to Implement ABS Challenge System in Triple-A Games

League memo indicates preference for challenge system over full automation, with major league adoption possible by 2026.

All Triple-A games will use the ABS challenge system starting June 25.
The challenge system allows players to contest balls and strikes in real time.
Surveys show 61% of team personnel and 47% of fans prefer the challenge system.
Technological hurdles remain, including setting accurate strike zones for each player.
The earliest the system could be implemented in MLB is 2026.
