发明名称 Method and apparatus for practicing pitching a baseball
摘要 An apparatus and method are provided for practicing pitching a baseball. The apparatus can be configured to receive pitches thrown into a specific designated area of the strike zone and to reject pitches not thrown to the specific designated area. The apparatus alters the position of the strike zone to compensate for the positioning of a catcher behind home plate. The apparatus more accurately identifies the strike zone, and areas outside the strike zone, to which a pitcher should practice throwing pitches.
