In a bold yet balanced move, Major League Baseball has officially approved the use of the ABS Challenge System — a tech-enhanced way to challenge ball and strike calls — for the 2026 season. After years of testing in the Minors and successful trials during Spring Training and the All-Star Game, the league is ready to roll it out across all games, including the postseason.
Commissioner Rob Manfred announced the decision, citing fan feedback, testing data, and player preferences. The chosen format lets teams challenge umpire calls rather than having every pitch called by automation — a nod to preserving baseball’s human element.
Each team will receive two challenges per game, with more awarded in extra innings if needed. Challenges are issued immediately by the batter, pitcher, or catcher with a tap to their cap or helmet. A Hawk-Eye system — already used in other sports — reviews the pitch location in real time, with verdicts delivered in about 14 seconds on average.
“The Challenge System adds a layer of strategy while keeping the game moving,” Manfred noted.
One key reason for selecting the Challenge System over a full ABS model? Fan and player feedback. Fully automated strike zones slowed the pace of play and eliminated the art of pitch framing — a nuance catchers have long mastered.
The ABS zone is precisely defined: 17 inches wide, with height measured from 27% to 53.5% of a player’s height. This standardization aims to create fairness while preserving the unique feel of each at-bat.
With a successful overturn rate above 50% and most fans saying it improved their viewing experience, ABS looks poised to be a hit. Whether you’re a traditionalist or tech enthusiast, one thing’s for sure — the 2026 season will bring a whole new dimension to calling the game.
