The Boston Crimson Sox open their 2026 season Thursday in opposition to the Cincinnati Reds with a notable change to the sport: MLB’s new Automated Ball-Strike Problem System.

The system, generally known as the ABS Problem System, permits gamers to problem an umpire’s ball-or-strike name in actual time, aiming to make sure accuracy and add a component of technique to the game.

Powered by T-Cellular, the ABS Problem System tracks the exact location of every pitch relative to the batter’s individualized strike zone. When a problem is initiated, the result’s transmitted over a 5G community and displayed nearly immediately on stadium videoboards and broadcast feeds.

The know-how has been examined within the minor leagues since 2022 and was used throughout Main League spring coaching in 2025.

The Crimson Sox obtained an early look this 12 months in the course of the Grapefruit League play: In a sport in opposition to the Minnesota Twins in early February, cleanup man Willson Contreras challenged a strike-three name that was overturned to a ball within the first inning.

How the system works

Every group begins a sport with two challenges. If a problem is profitable — that means the unique name is overturned — the group retains it. If the decision stands, the problem is misplaced.

Extra challenges are awarded in additional innings.

Solely the batter, pitcher, or catcher can provoke a problem, and so they should achieve this instantly by tapping their helmet or cap. Managers and different gamers will not be permitted to help, and umpires can deny a problem in the event that they imagine exterior enter influenced the choice.

Not each ballpark will characteristic the system. Whereas the ABS Problem System shall be out there in all commonplace MLB stadiums, it won’t be used throughout sure particular occasions — together with the Mexico Metropolis Collection, the Area of Desires sport, and the Little League Basic — as a consequence of technical limitations.

Ballparks will show the variety of remaining challenges for every group utilizing “ABS” indicators, and every overview is designed to take solely seconds earlier than play resumes.

For broadcasters, MLB has issued new steerage: Whereas networks should show a strike zone graphic, they’re being requested to not visually distinguish between balls and strikes inside that field.

Past accuracy, the system introduces a strategic component. As a result of challenges are restricted, gamers should determine when it’s price risking one — weighing early-inning calls in opposition to probably extra consequential moments later within the sport.
