摘要

A apparatus for improving pitching mechanics of a pitcher has a base, a member extending vertically upwardly from the base, a boom extending horizontally outwardly from the member, and a first indicator affixed to the boom for corresponding in relative location to a position where the pitcher's lead foot or lead shoulder should be positioned. A second indicator is connected to the boom for corresponding in relative location to the desired release point of a pitch by the pitcher. The member is adjustably positioned in height relative to the base.
