ABSTRACT:
A bowling ball includes a spherical inner core and an outer shell. An annular weight block is mounted symmetrically on a mid-plane of the inner core and is axi-symmetric about a centerline passing through the geometric center of the spherical body. An eccentric weight block is formed integrally with a portion of the annular weight block. The annular weight block is oriented such that the longitudinal centerline is positioned in a preferred attitude relative to the bowler release axis for controlling migration of a bowling ball spin axis from the bowler release axis to the longitudinal axis of the annular weight block as the ball slides and rolls down a lane.
