A golf ball is provided that has a cover layer with an increased hardness. The golf ball may have an inner core made from a highly neutralized polymer. The golf ball may have a four-piece construction, including an inner core, an outer core, a mantle layer, and the cover layer. The cover layer may be made of a thermoplastic polyurethane. The thermoplastic polyurethane cover layer may be formed of a material having a plaque hardness of at least about 44 Shore D. For example, the cover layer may be formed of a material having a plaque hardness of from about 44 to about 50 Shore D, or about 46 Shore D in particular. |
