Schauffele held off Rory Sabbatini, a South African playing for Slovakia, his wife’s native country, who blistered the course with a final round 10-under 61 that was good enough for the silver.
The battle for the bronze went on after the round was complete and included seven players. Several major champions were in that group, including Rory McIlroy of Ireland, Hideki Matsuyama of Japan and Collin Morikawa of the United States.
