ABSTRACT:
A device for training a pitcher or thrower, the device having a form that simulates the ball for which the pitcher is to be trained, examples being a softball or baseball. The device is constructed to allow one part of it to visibly rotate while one or more additional parts of the device visibly do not. It has a surface similar to the surface of the ball for which the pitcher would train, and a means to emit a distinctive and easily audible sound when it is properly thrown.
