ABSTRACT:
A golf ball includes 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 intermediate layer disposed about the inner core and being formed from a second substantially homogenous rubber-based composition such that the outer core layer has a hardness of about 20 Shore D to about 80 Shore D; and a cover layer disposed about the intermediate layer. A hardness of the first outer surface is 61 Shore C to 83 Shore C and is lower than a hardness of the geometric center to define a negative hardness gradient having a magnitude of up to −10.
