Pitching Tips: Gripping The Ball
Gripping the ball properly may seem fundamental, but many young players make mistakes when gripping the baseball. Teach your players that holding the ball in their fingertips - as opposed to jamming it into the hand - will help them get good velocity and wrist snap for control.
Have your pitchers vary their grips on the seams to experiment with the fastball and change ups. For example, gripping the with seams causes the pitch to sink; gripping the ball across the seams makes the pitch appear to rise.
