Claim:
1. A golf ball comprising: a center having a diameter of less than 1.500 inches, a compression of greater than 60, and formed from a polybutadiene composition; an outer cover layer formed from an ionomer composition, the ionomer composition having a flexural modulus of greater than 40,000 psi; an intermediate layer disposed between the center and the outer cover layer, the intermediate layer having an outer surface hardness of less than 50 Shore D and being formed from a composition having a solid, single core compression of 40 or less; wherein the outer surface hardness of the intermediate layer is less than that of both the center and the outer cover layer; and wherein the compression of a first golf ball subassembly consisting of the center, the intermediate layer and any optional layers disposed between the center and intermediate layer is less than the compression of a second golf ball subassembly consisting of the center and any optional layers disposed between the center and intermediate layer but excluding the intermediate layer itself, and the difference between the compression of the first golf ball subassembly and the compression of the second golf ball subassembly is 10 compression points or more.
