The Automated Ball-Strike (ABS) Challenge System, powered by @TMobile, will be used during the 2025 #AllStarGame!

The All-Star Game will feature the same rules as Spring Training: each team starts the game with two challenges apiece, with correct challenges being retained. Challenges can only come from the pitcher, catcher or hitter without any assistance from the dugout. A challenge occurs when the player taps his cap or helmet to alert the umpire and initiate the challenge.
