ABSTRACT:
A free standing, portable device for teaching pitching technique for softball or baseball. The device consists of a folding h-shaped base that rests on the ground and supports a removable vertical member. A horizontal track member is removably secured to the vertical member and can be adjusted in height on the vertical member to match the height of the pitcher. A ball attaches to the horizontal track member and can travel along the horizontal track member as the pitcher executes a pitch while grasping the ball. The ball is mounted to the horizontal track in such a way that the ball is free to spin in either direction relative to the horizontal track. In an alternate embodiment, an optional curved track can replace the horizontal track member in order to facilitate teaching additional pitching techniques.
