ABSTRACT:
A golf ball comprising a thermoplastic inner core layer that has a geometric center hardness greater than its surface hardness to define a “negative” hardness gradient. An outer core layer is disposed about the inner core and is formed from a substantially homogenous thermoset composition, typically rubber, and has an inner surface hardness substantially less than its outer surface hardness to define a “positive” hardness gradient. An inner cover layer is disposed about the outer core layer and an outer cover layer is disposed about the inner cover layer.
