Major League Baseball is trying something new this spring as they're allowing teams to challenge two ball and strike calls per game with the ABS challenge system. Players, managers and fans have been growing more and more frustrated with umpires over the years and this step to at least experiment with the challenge system seems like a good move for everyone involved.

ABS is MLB’s name for an automated strike zone — also known as robot umps. In a full ABS game, there will be a human umpire behind the plate, signaling the calls communicated through ABS. We won’t be seeing that full system in action this spring. Instead, teams will have a limited amount of challenges.

ABS has arrived at Goodyear Ballpark where the Guardians and Reds play their Cactus League home games this spring. It was on display Saturday when the Guardians and Reds opened the spring season against each other.
