Claim:
A golf ball comprising: a single layer core and a cover layer disposed about the single layer core; said 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 intermediate core region disposed about the inner core region and extending radially from about 8 mm to about 16 mm from the geometric center, and an outer core region disposed about the intermediate core region and being adjacent the outer surface and extending radially greater than about 16 mm from the geometric center; the single layer core further having a first hardness disposed within the inner core region of from about 35 Shore C to about 80 Shore C, a second hardness disposed within the outer core region of from about 35 Shore C to about 78 Shore C, and a third hardness disposed within the intermediate core region of from about 45 Shore C to about 95 Shore C, wherein the third hardness is greater than the first hardness and the second hardness and a hardness of the outer surface is substantially the same as or lower than a hardness of the geometric center by from about 0 shore C to about 25 Shore C.
