Quick Summary

In baseball, the strike zone is a specific area over home plate that a pitched ball must pass through to be called a strike. The dimensions of this zone are determined by the batter's height, with an upper limit at the midpoint between the shoulders and pants, and a lower limit at the bottom of the knees.1

Recently, Major League Baseball has introduced the Automated Ball-Strike Challenge System (ABS). This technology uses Hawk-Eye cameras to track pitches and determine if they fall within the strike zone, allowing players to challenge umpire calls. The ABS strike zone is defined as 17 inches wide, with the bottom at 27 percent and the top at 53.5 percent of a player's height, which differs slightly from the umpire-called zone.2
