Baseball practice device |
摘要 |
A baseball practice device in which a baseball is releasably attached to a "Y" shaped tether system which, in turn, is supported by two horizontal arms arranged in a "Y" shaped configuration. The combination of the horizontal arms and the tether system allows simulation of a pitching environment where the baseball may be presented to the batter with a uniform and repeatable flight path to enhance batting practice.
