Yankees shortstop José Caballero makes MLB history, becomes first player to use Automated Ball-Strike System

New York Yankees shortstop José Caballero made MLB history Wednesday: He became the first player to use the Automated Ball-Strike System (ABS).

During the fourth inning of the Yankees’ 7-0 Opening Day win over the San Francisco Giants at Oracle Park, Caballero challenged home plate umpire Bill Miller’s strike call after Giants starting pitcher Logan Webb threw a sinker at the top of the zone.

Caballero, 29, tapped his head to initiate the challenge and appeal the strike call, but lost the challenge.
