Abstract
A multi-layer golf ball includes a core having an outer surface, an intermediate layer surrounding the core, and a cover layer surrounding the intermediate layer, which defines an outermost portion of the ball. The outer surface of the core includes a plurality of polygonal protrusions aligned on a common sphere and a plurality of grooves that extend radially inward from the sphere and respectively separate and define each of the polygonal protrusions. The intermediate layer has a radially inward facing surface that is bonded to the outer surface of the core across the entire outer surface.
