Europe's miserable second morning at the Ryder Cup concluded when star pairing Rory McIlroy and Graeme McDowell were upset by Jim Furyk and Brandt Snedeker in an erratic foursomes.
The Northern Irish pair failed to make a birdie until the 14th hole, by which time the Americans were two holes ahead.
Another at 16 set up a nervy finale, but Furyk and Snedeker held on up the last to avenge their defeat to the same pair in Friday's opener.
Furyk's confident birdie putt at the first gave the home pair the perfect start, and they went two up with another birdie at the long fifth after McIlroy's 20-footer slipped wide.
McIlroy and McDowell continued to be frustrated on the greens, although they pulled a hole back when the home pair made a mess of the short eighth.
But Furyk restored the two-hole lead with a delicate downhill birdie putt at 11, and the unflappable veteran rapped in from four feet at the 14th to halve the hole in fours.
McIlroy finally got a putt to drop for a win at the 16th, but he shaved the lip at the next before striping a drive down the centre at the last.
But McDowell tugged his approach long and left, and McIlroy's 50-foot putt from the fringe again grazed the cup as the American's safely two-putted to clinch the point.
