Challenge System will take its next measured step toward regular-season implementation when it is used in the All-Star Game.

Major League Baseball's automated ball-strike challenge system will be in use at the All-Star Game on Tuesday, July 15, in Atlanta, GA.

MLB will feature the use of the automated ball-strike challenge system during Tuesday's All-Star Game at Truist Park in Atlanta. The move to use the ABS system during the All-Star Game comes after positive reception from the fans when the league successfully tested it during this year's Spring Training.
