The world's top pro golfers compete at the 2025 season's final major tournament at Royal Portrush Golf Club's Dunluce Course in County Antrim, Northern Ireland. That includes the event's favorites Scottie Scheffler and this year's Masters champion Rory McIlroy, as well as the Open's defending champion Xander Schauffele.
