The Insider Bat Baseball Spinner will help pitchers, catchers, and coaches to better understand the rotation of the ball and what is required to impart that rotation.
The Insider Bat Baseball Spinner is the exact diameter and weight of a baseball. It is a valuable tool to ingrain the proper mechanics of overhand throwing in all players. It can be used exclusively by pitchers for learning proper rotation on a baseball, which is required for movement.
All pitches can be thrown with the spinner including fastball, split finger fastball, curve, change, slider, sinker, and screwball.
