    摘要： A golf ball including an inner core having a geometric center and a first outer surface, the inner core being formed from a first substantially homogenous rubber composition, and an outer core layer formed from a second substantially homogenous rubber composition, the outer core layer having a second outer surface. An inner cover layer is formed over the core and includes an ionomeric material. An outer cover layer is formed over the inner cover layer and includes a castable polyurea or a castable polyurethane. The first outer surface has a hardness of up to about 20 Shore C less than a hardness at the geometric center to define a negative hardness gradient inner core and the second outer surface has a hardness of up to 18 Shore C greater than the geometric center hardness to define a positive gradient outer core layer and a shallow positive hardness gradient core.
