Boo Weekley and Heath Slocum ensured the United States remained top of the Omega Mission Hills World Cup leaderboard for the second consecutive day after carding a three-under-par 69 in today's foursomes.
After an impressive 11-under 61 during the fourballs format on Thursday, the duo shot five birdies against two bogeys and hold a one-stroke lead over England's Justin Rose and Ian Poulter and Scotland's Colin Montgomerie and Marc Warren.
Retief Goosen and Trevor Immelman combined to card a three-under 69 to give South Africa sole possession of fourth place while Germany, Italy and Denmark are all tied for fifth.
The USA had been criticised by some for not sending a higher ranked pairing but Weekley, 43rd in the world rankings, and Slocum, 70th, proved their first day showing was no one-off to keep the United States on target for a potential 24th World Cup victory.
They started well with a birdie on the first before bogeying the par-four fourth, letting England move to the top of the leaderboard. But birdies on the seventh, ninth and 11th put them back on target and though they bogeyed the 12th, the USA picked up another shot on the 15th - the Jose Maria Olazabal signature hole - to claim back the lead.
