Article: Position your shooting hand so that your fingertips are perpendicular to the seams in the ball. This hand is responsible for launching the ball. Place your non-shooting hand on the side of the ball to act as a guide for the shot. Your palm may or may not be touching the ball while you’re preparing to shoot - you may have control of the ball with your fingers and thumb. Leave a little space between your palm and the ball, so the ball will be able to roll off your fingertips with ease. The ball should sit on your finger pads. Spread your fingers wide so you have greater control over the ball.
