Abstract: A method of manufacturing a multi-layer golf ball includes injection molding a core from an ionomeric thermoplastic material such that the core has an outer surface with a plurality of polygonal land potions aligned on a common sphere and a plurality of grooves extending radially inward from the sphere. The core is then positioned between a first hemispherical shell and a diametrically opposed second hemispherical shell, which are each formed from a rubber material. The first and second hemispherical shells are then compression molded such that rubber material conforms to the outer surface of the core. The rubber material is then cured to form a unitary intermediate layer that surrounds the core. Finally, a cover layer is molded about the intermediate layer through one of injection molding and compression molding.
