MLB to Test Automated Ball-Strike System in Spring Training 2026

As Major League Baseball (MLB) gears up for the 2026 season, a significant transformation could be on the horizon that promises to refine the way America's pastime is officiated. MLB has announced its plan to test an Automated Ball-Strike (ABS) system during the upcoming spring training, marking a crucial step in its initiative to potentially implement the technology league-wide over the next few years.

A Step Toward Modernization

This move arises from MLB's strategic plan to integrate technology into the game, aiming for a full deployment of the ABS system before the 2026 season commences. The effort reflects a forward-thinking approach to ensure accurate ball-strike calls, which have long been a contentious and subjective aspect of the game.

The current collective bargaining agreement between MLB and the Major League Baseball Umpires Association is set to expire on December 1, which could play a pivotal role in the negotiations surrounding the ABS system's introduction. As the end of the agreement looms, MLB is diligently working to align all parties involved in the game, from players to umpires, with this technological advancement.

Testing and Trials in the Minors

Versions of the ABS have already been tested across various levels of the minor leagues, including Triple-A. The experience gained from these implementations serves as the foundation upon which MLB builds its plans for broader utilization. Full ABS games employ the Hawk-Eye system, a technology renowned for its accuracy in line-call decisions in professional tennis, to directly relay ball-strike calls to the plate umpire.

Additionally, an ABS challenge system has been piloted, allowing teams to contest a set number of decisions on ball-strike calls made by umpires per game. The automated system reviews these challenges, providing an objective assessment that can either uphold or overturn the umpire's initial call. This dual-layered approach not only maintains the human element of officiating but also enhances accuracy by incorporating data-driven decisions.

Testing on the Big Stage

Looking ahead to spring training, MLB Commissioner Rob Manfred shared insights on the test's design: "I think we will have a spring training ABS test that will provide a meaningful opportunity for all major league players to see what the challenge system will look like." The carefully orchestrated exposure during this period will ensure that players, teams, and other stakeholders gain first-hand experience with the new system—a critical step in facilitating a smooth transition.

The gradual roll-out strategy is designed to acclimate teams and fans alike, indicated by Manfred's remarks, "It won't be in every single ballpark but we actually have a plan where every team will get meaningful exposure." By not saturating every venue immediately, MLB balances the traditional elements of the game with modern technological enhancements.

A Cautious Path to Innovation

This pioneering approach positions MLB alongside other sports that have successfully integrated technology to enhance officiating precision. Tennis, for instance, has embraced similar technology for several years to assist with line calls, illustrating the potential benefits for baseball.

As MLB navigates these changes, the league's commitment to advancing the game while respecting its rich history is evident. The forthcoming spring training tests will serve as a critical proving ground, reflecting baseball's willingness to embrace innovation while preserving the spirit that has enthralled fans for generations. With the stakes set high, all eyes will be on how this technological evolution unfolds in the coming seasons.
