An inexpensive, uncomplicated ball throwing apparatus to huff balls for hitting and fielding which includes a frame having a front end and a back end supported by a base. The frame has a firing bar hingeably attached to the frame. A pitching armature having a cup end, a hinged mid-point and an elastic band end is coaxially connected to the firing bar at the pivot hinge. A latching mechanism automatically releases the pitching armature at a firing point and includes a latch that attaches the pitching armature to the firing bar. An elastic firing band connects the elastic band end of the pitching armature and the back end of the frame. A latch release cord connects the latch to the front end of the frame and disengages the latching mechanism to release the pitching armature when the firing bar is pulled to a firing point thereby causing the elastic firing band to force the pitching bar to pivot about the pivot hinge. A cup head mounted on the cup end of the pitching armature is designed and mounted to enable the ball to be released from the cup head with backspin. The ball throwing apparatus imparts backspin to the ball each time the machine is actuated, for control and extreme accuracy, causing the ball to assume the flight path desired by the user. The ball throwing apparatus can be easily adjusted to provide a variety of throws and to control the backspin as well.
