How is the strike zone determined for a batter according to the ruling?

The strike zone for a batter is determined based on the batter's usual stance. This means that the strike zone is not a uniform measurement that applies equally to every player; rather, it is personalized depending on how the batter typically stands in the box when preparing to hit. The rule takes into account the height and posture of each individual batter, which may vary significantly from player to player.

This individualized approach allows for a more accurate assessment of what constitutes a strike, fostering fairness and reducing disputes over balls and strikes. The zone extends from the top of the knees to the midpoint of the batter's torso, ensuring that it aligns with the batter's natural hitting position, leading to a more dynamic and tailored game experience.
