ONE Softball is committed to bringing you technical information that is factual and modeled by what the best players actually do. We will periodically bring you short videos that show throwing biomechanics, drills, and tips.

This high-speed video clip displays how the hand is supposed to be positioned on the ball as the arm works through the throwing zone to ball release. We want to avoid having the hand on the side of the ball exactly at the time of release. This will cause a cutting or curving action, similar to that of a curve ball. You may notice that your athlete’s hand may slip to the side or even underneath the ball to cause this type of rotation. Although athletes will have variations in their arm slot and release point, still work to keep the hand behind the ball at release. There will be backspin on the ball, but it will tilt and work on a different axis of rotation.
