ABSTRACT:
Two hemispherical ball components are joined to permit one to be rotated relative to the other. Each component not only defines the ball's spherical surface but also defines a "flat" minor spherical segment. By manually manipulating the flat on one component relative that on the other one can provide any number of trick throws or pitches to confuse a batter.
