The United States maintained a slim lead after Saturday's morning foursome matches at the Presidents Cup.
The Americans grabbed two points over the International Team in four contests at par-72, 7,380-yard Jack Nicklaus Golf Club Korea in Incheon, west of Seoul, for a 7 1/2 to 6 1/2 lead. The United States won one, halved two others and lost one.
The morning rounds were delayed by an hour because of rain.
The United States entered Saturday with a 5 1/2 to 4 1/2 lead. The Americans led 4-1 after Thursday's foursomes, but the International Team fought back with three four-ball victories on Friday to eat into the deficit.
The United States has won eight of the 10 Presidents Cups so far, including the last five.
Bae Sang-moon, the only South Korean in action, teamed up with Hideki Matsuyama of Japan for half a point against Bill Haas and Matt Kuchar. Bae and Matsuyama won the opening hole for a quick lead before the Americans battled back with a win at the sixth and ninth to go 1-up.
Matsuyama birdied the par-3 13th to draw even, and Bae chipped in for birdie at the par-5 15th to halve the hole and keep the match all square.
The Internationals, however, lost the par-3 17th after a poor tee shot by Matsuyama and a mediocre chip by Bae. They won the final hole with a birdie to salvage the half point.
The South African tandem Louis Oosthuizen and Braden Grace improved to a perfect 3-0-0 at this year's competition with a 3 & 2 victory over Patrick Reed and Rickie Fowler.
The International duo won two of the first three holes with birdies, and lost only two holes en route to their third win together.
"We played solid again. I had a few poor iron shots, but I putted well on the holes that I didn't hit the greens," Oosthuizen said. "Branden's always going to cheer you up and is always keeping you nice and positive. It's been good. We've been really a good team this week."
The all-Australian team of Adam Scott and Mark Leishman got half a point against Bubba Watson and J.B. Holmes. The Americans led 1-up through 15, but Watson missed a par putt to lose the par-4 16th, allowing the match to go all square.
In the final match, Dustin Johnson and Jordan Spieth rallied from 3-down at the turn to beat Jason Day and Charl Schwartzel 1-up. Spieth, who'd been struggling on the greens the past two days, made birdies on both the 17th and 18th to key the come-from-behind victory.
Spieth and Day, ranked first and second in the world, went toe-to-toe for the first time this week. They will meet again in the four-ball match later Saturday. (Yonhap)
