    Abstract: A golf ball includes a single core formed from a substantially homogenous rubber composition, an inner cover disposed about the core, and an outer cover. The inner cover includes an ionomeric material and has a hardness of about 60 Shore D or greater. The outer cover layer is disposed about the inner cover layer, is formed from a castable polyurea or polyurethane, and has a material hardness of about 60 Shore D or less. The outer surface of the core has a trans content of about 12% or less and a hardness of about 71 to 88 Shore C, the geometric center of the core has a trans content of about 10% or less and a hardness of about 70 to 80 Shore C, and the core surface hardness is greater than the geometric center hardness by about 1 to 10 Shore C to define a shallow positive hardness gradient.

    Abstract: A golf ball with a controlled moment of inertia and controlled spin rate is disclosed. The golf ball comprises a subassembly and a cover, the subassembly comprising an inner core and an intermediate layer, wherein the subassembly has a diameter of from about 1.45 inches to about 1.66 inches, the inner core has a diameter of less than about 0.75 inches, and the intermediate layer comprises a foamed polyurethane composition. The inner core has a specific gravity of higher than about 1.15, the intermediate layer has its specific gravity reduced to less than about 1.05, and the subassembly has its specific gravity reduced up to about 8% such that the coefficient of restitution of the subassembly is controlled by or is substantially the same as the coefficient of restitution of the intermediate layer, and the golf ball has its coefficient of restitution reduced by less than about 6%.
