Abstract
A golf ball including an inner core having a first outer surface and a geometric center and being formed from a first substantially homogenous composition such that the inner core has a hardness of about 60 Shore C to about 90 Shore C; an outer core layer disposed about the inner core having a second outer surface and being formed from a second substantially homogenous composition such that the outer core layer has a hardness of about 60 Shore C to about 95 Shore C; and a cover layer disposed about the outer core layer. The geometric center and first and second outer surfaces each have a hardness, the hardness of the second outer surface being lower than the hardness of the geometric center to define a negative hardness gradient.
