Abstract
A golf ball comprising an innermost core, an outer core, and a cover is disclosed. At least a layer of the golf ball is made from a low compression, high coefficient of restitution material, and is being supported by a low deformation, high compression layer. The resulting golf ball has high coefficient of restitution at high and low impact speeds and low compression for controlled greenside play.

A golf ball comprising:
- a single, solid layer innermost core having a Shore C hardness of greater than 70 and a flexural modulus of from 80,000 psi to 200,000 psi;
- a cover;
- and
- a intermediate layer disposed between the innermost core and the cover, wherein the intermediate layer comprises a rubber composition containing a halogenated organosulfur compound and has a thickness of from 0.001 inches to 0.100 inches, a Shore C hardness of from 25 to 70, and a flexural modulus of from 500 psi to 25,000 psi;
- and wherein the core and the intermediate layer have a diameter of greater than 1.50 inches and a compression of greater than about 80.
