Abstract: A ball spinning device which has one or more balls, each ball having the surface appearance of a baseball. For an embodiment that has more than one ball, all balls are positioned in a straight line by connecting spindles. A power transferring spindle is sized and shaped so it can be connected to an electric motor which is capable of spinning the device at the same speeds as those of pitched baseballs. For each ball, its axis of rotation relative to its seam is determined by where spindles are joined to the ball with respect to its seam.
