Abstract
A baseball pitching machine includes a pair of adjacent ball engaging wheels each provided with a groove or concave surface formed in a body of an elastomeric material. As the baseball is received between the grooved wheels, the groove edges are laterally distorted, since the edges are unrestrained, to grip the baseball securely on opposite sides thereof and pitch the baseball in an accurately predetermined direction.
