Xander Schauffele hit the winning putt as the United States retained the Presidents Cup with an impressive 17½-12½ win over the international team.
USA led 11-7 overnight but lost the first single of the final day when Si Woo Kim beat Justin Thomas by one hole.
However, needing 15½ points for victory, Jordan Spieth, Patrick Cantlay and Tony Finau went on to win their matches while Sam Burns picked up a half point.
Schaule held Corey Conners through a hole to seal the cut on his side.
The biennial Ryder Cup-style event was held in Quail Hollow, North Carolina and the home side’s win gives them a 12-1 lead in the event, with a game tied.
“It feels good to win. It got really close for a little while. Winning is winning and there are no pictures on the scorecard,” said Schauffele, who struggled to his best golf in the game against the Canadiens.
USA captain Davis Love added: “They played really well. It was tough. They put in a lot of effort the last three weeks. They came in ready to go.”
Spieth has been superb in this Presidents Cup – producing a record 100% in his five matches – and he got the USA team back on track with a 4&3 win over Australia’s Cameron Davis.
Spieth’s win was his first in eight Ryder and Presidents Cup singles matches.
“I was very nervous,” he said. “I wanted to get rid of this monkey. They’re looking for red on the board and it’s really good to finally provide them with that.
“You can’t put a price on that. I did everything I could this week.”
Burns tied his match with Japan’s Hideki Matsuyama, while Cantlay beat Australia’s Adam Scott 3&2.
Colombian Sebastian Munoz beat world number one Scottie Scheffler 2&1 to make it 13½-9½ and it started to close with several international players in their matches.
However, Team USA’s superior putt was the difference between the sides and Finau’s 3&1 win over Canadian Taylor Pendrith took the USA one point away from their goal before Schauffele pulled away. secures with a solid par putt at the end.
There were contrasting fortunes for two South Koreans who look set for glittering careers.
Sungjae Im beat Cameron Young, likely to be an American stalwart for years to come, by a holeshot while Tom Kim – hero of yesterday’s fightback – was edged out on 18 by Max Homa.
Another South Korean, KH Lee, was an impressive 3&1 winner against Billy Horschel as the international team played for pride after the match victory.
In the last two matches, Chilean Mito Pereira was comfortably beaten by Collin Morikakwa, but South African Christiaan Bezuidenhout finished with a point for the Internationals against Kevin Kisner.
“We are a bit disappointed,” said international captain Trevor Immelman. “We believed in ourselves.
“We had an amazing week. They were fighting. These guys have huge hearts. I’m going to fight them anytime.”
Few expected the game to still be in progress until the final hour of play on Sunday after Team USA took a 4-1 lead after day one.
However, they showed heart and skill in pushing Love’s side all the way and signaled a successful future both individually and collectively.
Immelman was deprived of LIV players Cameron Smith – the Open champion and world number three – as well as Chilean rising star Joaquin Niemann, Mexican Abraham Ancer, South African Louis Oosthuizen and Australian Marc Leishman.
They are banned from playing after joining the Saudi-funded start-up, meaning Immelman has eight rookies in his 12-person squad.
The Americans were without Dustin Johnson, Bryson DeChambeau and Brooks Koepka, although Team USA still had 10 of the top 16 players in the world.
