Abstract: A pitch training ball includes a center portion, a first cap, and a second cap. The center portion is opaque and has a first planar surface at a first end thereof, and a second planar surface at a second end thereof opposite to the first end. The first cap portion has a first base that is adjacent to the first planar surface. The second cap portion has a second that is adjacent to the second planar surface. The first cap, the center portion, and the second cap cooperate to define a baseball shape. The first and second caps are transparent to translucent.

Abstract: A device for training a person to throw a ball includes a body. The body defines a first planar surface, a second planar surface, and a curved surface. The first planar surface is defined at a first end of the body. The second planar surface is defined at a second end of the body. The curved surface is defined between the first planar surface and second planar surface. The device has a center of mass that is located outside of the geometric center of the device.

Abstract: A pitch training device used to improve the throwing technique of balls used in sports. The device includes a core and a substantially disk-shaped body that provides immediate visual feedback as to whether the device was properly thrown. The core exhibits a density greater than the density of the body, thereby mimicking the moment of inertia of many sports balls. This, in turn, allows the user of the device to improve the training techniques used to increase spin efficiency of a ball while also helping train and improve other throwing techniques.
