Abstract: Provided herein is a device useful for delivering spherical projectiles to a desired location. The projectiles may comprise baseballs, tennis balls, or the like, and may be conferred with various degrees of linear velocities, spin, and rotational characteristics for their flight. A device according to the invention is especially well suited for use in providing batters with a source of various pre-selected or random pitches of balls, to enhance batting practice in the absence of a human pitcher. A device according to the invention is readily compactable, portable, and efficient with regard to the amount of space it occupies.
