| abstract |
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 wherein an inner core region is disposed about the geometric center and an outer core region is disposed about the inner core region and is adjacent the outer surface, the outer core region having a thickness of about 15 mm or less. The inner core region has a first hardness (IC 1h ) and the outer core region has a second hardness (OC 2h ) such that the second hardness (OC 2h ) is greater than the first hardness (IC 1h ), represented by the relationship (OC 2h )>(IC 1h ) and a hardness of the outer surface (OS h ) is greater than a hardness of the geometric center (GC h ), represented by the relationship (OS h )>(GC h ) to define a positive hardness gradient. |
