The basic task of the pitcher is to throw the ball so that it passes over the home plate at a height between the batter’s knees and shoulders. In baseball, the strike zone extends from the knees to a point midway between the shoulders and the top of the pants. In fast pitch softball the strike zone is essentially the same, although the upper part of the zone is defined as the bottom of the sternum. In slow pitch softball, the zone extends to the shoulders.
