Xander Schauffele steadied after a late wobble to clinch gold for the United States in Olympic golf on Sunday with a one-stroke victory as South Africa-born Rory Sabbatini claimed an unlikely silver for adopted nation Slovakia.

Taiwan's CT Pan, who had enlisted his wife to be his caddie, claimed the bronze, eliminating American Collin Morikawa on the fourth extra hole of a playoff on a scorching day at Kasumigaseki Country Club.

"Man, it feels good," said Schauffele, who claimed the title with a final round 67 for an 18-under total of 266.
