ABSTRACT:
A low silhouette oscillating platform upon which may be mounted a device or machine for throwing balls to a player or players for catching or batting practice. The oscillating platform allows the pitched balls to be distributed at random within any point of a specified arc. The platform may be permanently attached to the throwing device or attached by quick-disconnect latches, thereby allowing removal for storage. The platform may be left attached to the throwing device and not electrically activated for throwing or pitching to a fixed point.
Two wheels are so affixed to the platform that, when required, they may be used to move or transport the entire assembly. The lower surface of the platform is smooth or padded to protect the surface upon which it is placed, which may be a smooth tennis court.
