ABSTRACT:
A golf ball comprising a thermoplastic core, the core having an outer diameter of 1.51 inches to 1.59 inches and having an outer surface and a geometric center, each having a hardness; an outer cover layer; and an inner cover layer disposed between the core and the outer cover layer; wherein the thermoplastic core has been exposed to a gradient-initiating solution comprising sufficient amount of plasticizer such that the hardness of the outer surface is less than the hardness of the geometric center to define a “negative” hardness gradient of 5 Shore C or greater.
