Through the new system, human umpires will still call balls and strikes, but teams have a limited number of challenges with which they can appeal on-field decisions. Teams retain the challenge if they are successful.
The ABS technology uses Hawk-Eye cameras to track the location of each pitch in relation to the strike zone.
The automated ball-strike (ABS) challenge system will be trialed at 13 ballparks hosting 19 teams in 2025 to allow players to experience the new technology as the league works out how best to implement it, according to MLB commissioner Rob Manfred.
Although Manfred admitted that he “would be interested” in bringing in the ABS challenge system for the 2026 regular season, the commissioner added that the players’ experience with it will go a long way in deciding when it will be implemented.
Fun Fact:
Cricket is much more advanced technologically than Baseball. Cricket had DRS implemented for a long long time ago. The third umpire plays the role of using technology for making decisions.
