MLB TV viewers will notice a significant change this season: the strike zone box will no longer indicate whether a pitch is a ball or a strike. This decision comes as the league introduces the automatic ball-strike challenge system, which will allow players to challenge umpire calls within a few seconds. The league is taking precautions to prevent players from gaining an unfair advantage by implementing a delay in pitch location data and removing the strike zone box from low-latency feeds inside the ballpark. This change marks a departure from the K-Zone, which was first introduced in 2001 and has been a staple of MLB broadcasts ever since. The ABS challenge system, tested in Triple A and during the 2025 MLB spring training, will now be fully operational this spring and in the regular season. Teams have limited opportunities for challenges, with two incorrect challenges per game and an additional one in extra innings. The league's actions aim to balance fairness and excitement, ensuring that the game remains competitive and engaging for fans at home.
