Abstract: A game ball with a generally spherical inner ball and a cover substantially covering the inner ball. The inner ball has first and second halves divided by an imaginary equatorial plane. There are circumferentially spaced openings in the first half of the inner ball and openings in the cover aligned with the openings in the inner ball. The game ball curves away from the openings when thrown and thus may be used for learning how to throw and hit breaking pitches.
