Major League Baseball decided to continue testing the automatic balls and strikes (ABS) challenge system during Tuesday night's All-Star Game at Truist Park in Atlanta. The league tested the system in spring training. Now, the Midsummer Classic provides a new, bigger stage for a potential rule change MLB is clearly mulling over.
For ABS challenges Tuesday, the same process as spring remained in place. Each team is allowed two challenges, with the ability to keep them if they are successful. The pitcher, catcher, and batter are the only three who can call for a challenge, which must happen immediately after a pitch. No outside help from the dugout is allowed.
