Major League Baseball broadcasts no longer will use the strike zone box to indicate where ​the pitch was a ball ‌or a strike, a move that coincides with the league’s implementation of the automated ball-strike challenge system.

The box itself still can ‌be ​used, but viewers ⁠will have to gauge ⁠for themselves whether the pitch was a ball or a strike.

The change is being made so that ​players can’t be tipped off through a signal as to whether ⁠to challenge a ⁠strike call. Teams will be ​allowed to challenge two calls in ​each regulation game.

MLB will begin using ‌the ABS system this season after it was tested in Triple-A and during 2025 MLB spring training games. ⁠It will make its formal debut on March 25 on Opening Night when the ⁠New ‌York Yankees visit the San ⁠Francisco Giants in the ​first-ever ‌live MLB broadcast on Netflix.

“With ​ABS now ⁠determining the zone,” an MLB spokesperson said, per Yahoo, “we want fans to trust the system without second-guessing every call through a digital strike box.”
