摘要： A ball training system for pitchers for effectively improving the pitching abilities of a baseball or softball pitcher. The ball training system for pitchers generally includes a ball training device including a core having a first side and a second side, an exterior cover surrounding a portion of the core, a plurality of seams attached to the exterior cover, a first cover attached to the first side of the core, and a second cover attached to the second side of the core. The first side and the second side of the core are each preferably planar and parallel to one another. When the ball training device is properly thrown by a pitcher, the ball training device's flight is substantially smooth and if the improperly thrown the ball training device will wobble inflight.
