Tiger Woods and Steve Stricker kept America in control on the penultimate day of the Presidents Golf Cup, taking their record to a perfect 4-0 as the United States built a three-point lead over the Internationals.
The Americans lead 12.5-9.5 and need five points from the last 12 singles matches in order to win their sixth title in eight editions of the event that pits the US against a team from all corners of the globe except Europe.
Woods and Stricker won their morning foursomes thanks to a show of steel from 14-time major champion Woods.
The world number one then had little to do but applaud as Stricker made seven birdies en route to their afternoon four-ball triumph.
Woods and Stricker were 1-down and facing their first defeat in three matches in the foursomes against Canadian Mike Weir and South African Tim Clark.
Woods rolled in a 22-footer to square the match at 17, the ball nearly rolling to a halt before dropping in.
His jubilant fist pump ignited the crowd, and at 18 the show continued as Woods put the Americans eight feet from the pin in two while Weir and Clark were in the greenside rough and the Americans won the hole and the match with a conceded eagle.
In the afternoon four-ball, Woods and Stricker teamed up for the fourth time in the week and built a 6-up lead through 12 over South Korea's Yang Yong-Eun and Japan's Ryo Ishikawa.
The Asian duo then won the next three holes with birdies to keep the match alive, before Woods and Stricker polished them off 4 and 2.
