A baseball suitable for continuous use in a pitching machine comprises a molded, resilient polyurethane foam sphere having a type A-2 shore durometer hardness of less than about eighty to eighty-five. The sphere has a smooth polyurethane surface skin, with the surface of the sphere being provided with a regular pattern comprising a multiplicity of cup-like or hemispherical depressions substantially covering the surface. The baseball has the advantage of durability as well as the advantage of being formed economically in one operation from a homogeneous composition. The cup-like depressions enable the ball to travel greater distances than would be expected for the resilient material, and enhance the accuracy with which the ball can be pitched, bringing the ball substantially within the range of initial performance of a conventional or regulation baseball. The ball is pitched in a pitching machine providing backspin and the depressions appear to cause turbulent airflow enhancing lift and drag factors on the ball as well as stabilizing its flight path. The ball resilience further enhances the ease with which it is manufactured since the ball can be easily removed from a simple mold despite the presence of mold projections used to form the aforementioned depressions.

Baseball

A baseball batting range includes a plurality of pitching machines positioned for propelling baseballs toward corresponding batting stations. The range further includes a sloping floor and a sump where the batted baseballs are collected, and a conveyor which delivers the balls from the sump to a distribution hopper elevated with respect to the sump and the pitching machines. Gravity tube magazines fed from the distribution hopper hold a number of baseballs which are metered to the respective pitching machines. The sump and the distribution hopper are provided with agitators facilitating continuous movement of the baseballs.

Baseball batting range retrieval system

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.
