An economical relief pitcher in which there is employed a plurality of tubes, at least one of them being employed as a firing tube and at least one being employed for storing balls to be fired, the firing tube being connected with a high volume source of air. A remote push actuator can be employed to actuate a rocker arm and actuator device for allowing a single ball at a time into the firing tube which is connected with a high volume source of air for firing. A delay is employed for effecting a delay from the pushing of the push actuator until the ball is fired. A lower tapered orifice is preferably employed for creating a suction pressure to help the balls get into the firing tube.
