the velocity of the ball at release. When the arm is drawn upward and backward during the delivery, the pitching arm should be kept close to the head and right ear, and should brush the right hip prior to delivery (Figure 7). These cues will help the pitcher to keep the arm on a straight path (Mogill 1984).
