ABSTRACT:
A golf ball includes an inner core having a first outer surface and a center formed from a homogenous composition such that the inner core has a hardness of 40 to 80 Shore C; an outer core layer disposed about the inner core having a second outer surface and an inner surface, formed from a homogenous composition such that the outer core layer has a hardness of 60 to 90 Shore C; and a cover layer including at least two layers. The center, first and second outer surfaces, and inner surface each have a hardness, the first outer surface hardness being lower than the center hardness to define a negative hardness gradient, and the second outer surface hardness being greater than the inner surface hardness by 10 to 20 Shore C to define a positive hardness gradient.
