The present invention relates to a game ball for pitching having an upper hemisphere (12) with a plurality of openings (16) that draw air into a hollow spherical shell (10). The base hemisphere 14 has no holes and is provided with a plurality of air channels 20 that are spaced apart from the equatorial line 22 and arranged in parallel. When projected along the plane of the equatorial line 22, the ball deviates in the axial direction of the base hemisphere 26 from the normal orbit.
