Patrick Cantlay made a dramatic birdie putt at 18 from just inside 17 feet in near-darkness to give the United States a 11-7 lead over the Internationals after Saturday's matches at the Presidents Cup.

Cantlay delivered a 1-up foursomes victory with second-ranked Xander Schauffele over South Koreans Tom Kim and Kim Si-woo, the latter missing a tying putt at 18 after a tough fight at Royal Montreal.

"The Kims played unbelievably well. They stuck it to us on a lot of holes," Schauffele said. "We're just happy to get away with a 1-up."
