Abstract
A multi-layer golf ball includes a core, and intermediate layer, and a cover. The core has an outer surface that includes a plurality of depressions extending from a spherical land portion. Each depression has a maximum depth relative to the spherical land portion of between 0.15 mm and 2.0 mm. The intermediate layer surrounds the core and has a radially inward surface that is flush with the outer surface of the core. The cover layer surrounds the intermediate layer and defines an outermost portion of ball.
