MLB ABS Challenge System Tracking for 2026: Team and Player Rankings

Major League Baseball implemented the ABS challenge system for the 2026 season, allowing players to challenge a call ball or strike made by the referee home plate. Each team begins the game with two challenges, and only hitters, pitchers and catchers can challenge a call. If a team wins a challenge, it retains the right to continue contesting. If a team incorrectly challenges twice, they lose their challenges for the remainder of the match.

Below are the ABS Challenge System rankings for hitters, catchers, teams, and umpires for the 2026 MLB season.
