Abstract
A multi-layer golf ball includes a core having an outer surface, and intermediate layer surrounding the core, and a cover surrounding the intermediate layer. The intermediate layer defines a radially inward facing surface that is flush with the outer surface of the core, and the cover defines the outermost surface of ball. The outer surface of the core includes a plurality of polygonal land portions aligned on a common sphere. The outer surface of the core further defines a first plurality of annular grooves disposed about a first axis, a second plurality of annular grooves disposed about a second axis, and a third plurality of annular grooves disposed about a third axis. The first axis, the second axis, and the third axis are mutually orthogonal, and each groove respectively extends from the common sphere and is concave relative to the core.
