Tennis Ball Can

This drill is for the pitcher looking to learn the proper feel for a true curveball. Don´t throw curveballs until about 14-15 years of age.

Fill a tennis ball can with some rocks to give it weight. Go through the wind-up and throw the tennis ball can in the same manner you would throw a curveball. The goal is to get the can to spin perpendicular to the ground. This simulates the proper release point and arm angle necessary to throw a true curveball. The key is to get a 12 o´clock to 6 o´clock spin.
