Abstract: A ball throwing apparatus includes a ball feeding guide, an actuator with a movable stop member, a throwing arm and ball launching guide. The ball feeding guide defines a path open at and extending between first and second ends for receiving balls at the first end, guiding the balls in a single file arrangement along the path with the balls being movable by the force of gravity through the path and feeding the balls from the second end. The actuator is disposed adjacent to the second end of the ball feeding guide and its stop member is movable between an extended position in which the stop member blocks the path and thereby retains the balls in the single file arrangement within the path and a retracted position in which the stop member unblocks the path and thereby allows the feeding of balls from the path at the second end of the ball feeding guide.
