Claim:
A golf ball comprising: a single layer core and a cover layer disposed about the single layer core, the single layer core being formed from a substantially homogenous formulation and comprising a geometric center and an outer surface; the single layer core further comprising an inner core region disposed about the geometric center, an outer core region adjacent the outer surface, and an intermediate core region disposed between the inner and outer core regions and being at least about 2 mm radially from the geometric center and at least about 2 mm from the outer surface; the inner core region comprising a first hardness (IC 1h ), the outer core region comprising a second hardness (OC 2h ) and the intermediate core region comprising a third hardness (IMC 3h ) and a fourth hardness (IMC 4h ) such that (IMC 3h )<(IC 1h ) and (IMC 3h )<(OC 2h ), and (IMC 4h )>(IC 1h ) by from about 10 Shore C to about 55 Shore C, and (IMC 4h )>(OC 2h ), and wherein the outer surface has a hardness (OS h ) and the geometric center has a hardness (GC h ) such that (OS h )>(GC h ).
