Final-round play in the 153rd Open Championship from Royal Portrush Golf Club in Portrush, Northern Ireland. Americans have captured nine of the last 10 men's majors, with Xander Schauffele hoisting the Claret Jug in this event last year. A four-hole aggregate playoff would be used in the event of a tie after 72 holes. Northern Irishman Shane Lowry (15-under-par) won here by six in 2019, though no player in the final 12 groups broke par in brutal conditions.
