In the opening game of the 2026 MLB season, New York Yankees shortstop Jose Caballero made history by issuing the first in-game challenge under Major League Baseball's new Automated Ball-Strike System (ABS). However, Caballero's challenge was ultimately unsuccessful, as the ABS confirmed the umpire's original strike call.

Why it matters

The introduction of the ABS system marks a significant change in how balls and strikes are called in Major League Baseball, with the goal of increasing accuracy and consistency. This debut challenge highlights how the new technology will impact the game and players' strategies going forward.

The details

In the fourth inning of the Giants vs. Yankees game, home plate umpire Bill Miller called a high inside sinker from Giants starter Logan Webb a strike. Caballero tapped his helmet to challenge the call, but the ABS system quickly confirmed that the pitch was indeed a strike, as shown on the Oracle Park video board.

  • The ABS system was tested in the minor leagues since 2022 and in recent spring trainings.
  • The ABS system made its official debut in the 2026 MLB opening night game between the Giants and Yankees.
