Abstract
The present invention is directed to golf balls consisting of a multi-layer core and a cover. The multi-layer core consists of a center and an outer core layer that are both soft relative to a hard intermediate core layer. The outer core layer is preferably thin relative to the center and the outer core layer. The multi-layer core includes at least one layer formed from a low modulus HNP composition and at least one layer formed from a high modulus HNP composition.
