Hit by Pitch
A batter must make an attempt to avoid being hit by any pitched ball. When the batter fails to make a legitimate effort to avoid the ball, the pitch will be called a ball or strike relative to its position as defined by the strike zone, Rule 2-74 or 7-4. “Freezing” is no longer an acceptable method of avoiding being hit by a pitched ball. Allowing the ball to hit any part of the body will not be accepted as “hit by the pitch” and the batter will remain at the plate to complete his at-bat unless the pitch results in ball four or strike three.
