ABSTRACT:
A practice machine for receiving a thrown ball and returning it to a user is generally provided with a backstop for stopping the thrown ball, a pan disposed below the backstop for collecting the ball, a ball return adjacent the backstop for expelling the ball, and a trough disposed between the pan and the ball return for feeding the ball from the pan to the ball return. The ball return can adjust between ball sizes and vary the trajectory of expelled balls. Moreover, the ball return can be equipped with safety features including a proximity sensor, audible alerts, speed adjustment and tamper resistant controls. Further, the ball return can alternate between a MANUAL mode and an AUTOMATIC mode. The backstop of the practice machine can be collapsible to permit convenient storage and ease of transportation.
