8 year staying behind the ball


#1

My son is 8 and has been pitching about 1-1/2 years. He has a tendency to release the ball with his hand on the side of the ball (pinky first) Ive tried numerous drills to try to get him to stay behind the ball. Now he has been overcompensating and releasing the ball with his hand on the side of the ball (thumb first). If anyone has any drills to help or a way of explaining it to an 8 year old, please share.
Thank you

The standard drill for this is to put a piece of black tape or draw a black line around the center of a baseball. Then have your son throw the ball so as to keep the line from wobbling.
