A ball tossing device for batting practice comprises a self-contained, pneumatically controlled and actuated mechanism. The device includes a launcher comprising a pneumatic cylinder and ball carrier and a trough type feeder for sequentially supplying balls to the carrier for tossing. The pneumatic cylinder is actuated by compressed air from a regulated source of compressed air, with timer means which controls actuation of a valve to transmit the compressed air to the cylinder. The cylinder is a single action type with a return spring. The launcher may be angularly variable for non-vertical tosses.
