Machine for training a pitcher

A method for training a thrower comprising;

• (a) providing a simulated or regulation game ball divided into slices, said slices having essentially parallel planar faces, and comprising a first end slice, a middle slice, and a second end slice, such that said slices, when joined together, substantially constitute the overall form of an athletic game ball,
• (b) said first and second end slices joined to the middle slice by an axle attached to said end slices at an angle substantially normal to the planar faces of said end slices, the axis of said axle passing between the first and second end slices and through the center of the aforesaid game ball of which they comprise parts,
• (c) said axle also connected to or passing through the center of said middle slice at an angle normal to the planar faces of said middle slice,
• (d) said middle slice rotatably connected to the axle(s) and/or one or more of the end slices rotatably connected to the axle(s),
• (e) wherein further included is a means for generating a distinctive, audible sound when said center slice rotates,
• (f) wherein the center of gravity of the device substantially coincides with the center of the ball,
• (g) compelling the thrower-in-training to grasp the ball and throw the ball with the goal of causing the middle slice to rotate at high velocity while the end slices remain stationary,
• (h) observing the ball to establish whether, while the ball is in flight, the middle slice rotates and the end slices essentially do not rotate,
• (i) listening for the distinctive sound that is generated when the middle slice rotates about the axis of the axle(s), observing the orientation of the rotating middle slice, and
• (j) adjusting the thrower's manner of throwing to better cause the middle slice to rotate at desired orientation, thereby generating a distinctive audible sound, while at the same time causing the end slices to remain stationary.
