Major League Baseball is set to debut its new Automated Ball/Strike (ABS) system this summer, a high-tech addition that will revolutionize how umpires call balls and strikes. While the system aims to bring consistency, it has also sparked a debate over the role of human judgment in a sport steeped in tradition. Teams are now navigating the strategic implications of this technology, focusing on cohesive team strategies and the importance of the human element, especially from catchers with the best pitch perspective.

Why it matters

The introduction of the ABS system raises questions about the future of baseball and whether technology is enhancing or detracting from the sport's core traditions. As machines take over strike calls, the human elements of emotion, strategy, and teamwork are becoming the new battlegrounds on the diamond.

The details

The ABS system uses cameras to track each pitch and determine whether it crossed the home plate within the strike zone. Human umpires still make the final calls, but teams can challenge up to two calls per game. If a challenge is successful, the team retains it; if not, the challenge is lost, unless the game goes into extra innings. Only batters, pitchers, or catchers can initiate a challenge, and they must do so within two seconds by tapping their helmet or cap. During last year's spring training tests, teams successfully challenged 52.2% of 1,182 calls, with each review averaging just 13.8 seconds.

  • The ABS system will make its official debut in regular-season MLB games this summer.
  • The system was previously tested during the 2022 Triple-A season.
