Major League Baseball (MLB) has announced that they will introduce the Automated Ball Strikes (ABS) Challenge system starting the 2026 season. This new technology aims to enhance the accuracy of ball and strike calls during games. However, MLB has specified that this system will not be applied during the highly anticipated Mexico City Series in April 2026, which will feature matches between the Arizona Diamondbacks and the San Diego Padres. The decision not to include the ABS system in the Mexico City games is notable, as this series is part of MLB's effort to expand its international footprint.

The reasoning behind the exclusion of the ABS Challenge in certain games, including the Mexico City Series, stems from the current technological infrastructure at the venues. MLB's rollout of the ABS system requires specific equipment and capabilities, which are not yet available at the three selected venues for exceptions, including the Mexico City Series. This means that while the rest of the MLB games will benefit from this technology, fans in Mexico will have to experience traditional officiating in these matchups.

This decision has implications for both players and fans, as the Mexico City Series is expected to garner significant attention and excitement. The introduction of the ABS Challenge aims to improve the fairness and precision of the game, yet the absence of this feature in one of the most visible international events underscores the challenges of integrating advanced technology within the sport while catering to different international markets.
