Abstract
A golf ball comprising an inner core, an outer core, and a cover is disclosed. The outer core surrounds the inner core, and the cover encases the cores. The inner core is preferably a pre-formed symmetrical, non-spherical insert, which may be made from a rigid material to improve the CoR and initial velocity of the ball at high impact speeds. The outer core is preferably over-molded around the pre-formed insert to form a spherical core.
