Ben Curtis produced a strong finish to beat Lee Westwood 2 and 1 in the penultimate match.
Curtis opened with a birdie, but then fell two down as Westwood made birdies at the second, fifth and sixth.
The former Open champ clawed one back with a birdie at seven but Westwood's eagle at 10 saw the Englishman go two up again.
However, back-to-back bogeys by Westwood at 11 and 12 put the match all square before he edged in front again with a birdie at 13.
But with Westwood sensing America were going to prevail regardless of what he did, Curtis responded to the cheers and birdied 14 and 15 to take the lead.
He finished with another at the 17th to secure his first full point of the contest while defeat for Westwood meant the joint top scorer from the last two Ryder Cups failed to register a single win in four starts.
