A method of making a golf ball may include molding at least one core layer and molding an outer cover layer radially outward of the at least one core layer, from an outer cover layer material, including forming one or more grooves extending radially inward from an outer surface of the outer cover layer. The method may also include molding a groove material within the one or more grooves, the groove material having a compressibility that is different from a compressibility of the outer cover layer material. In addition, molding the groove material may include forming the groove material such that an outer surface of the groove material extends radially outward beyond the outer surface of the outer cover layer.
