Wilson and Stenson defied the odds to claim a point for Europe in Kentucky
Henrik Stenson and Ryder Cup debutant Oliver Wilson produced a stunning comeback as Europe reduced the deficit to 7-5 against the United States.
The pair were four down after six holes against Phil Mickelson and Anthony Kim but hit back to claim a vital 2&1 win.
Justin Rose and Ian Poulter thrashed Stewart Cink and Chad Campbell 4&3 while Miguel Angel Jimenez and Graeme McDowell managed to claim a half.
Kenny Perry and Jim Furyk were the only US pair to win in Saturday's foursomes.
The American duo won the first hole against three-time major winner Padraig Harrington and Swede Robert Karlsson and they never looked back, finishing up 3&1 victors.
But overall it was a good morning for the Europeans, who went into the second day's foursomes 5½-2½ behind following a spirited opening from the home side in Valhalla.
But they had to do it without two star players after skipper Nick Faldo decided to rest Lee Westwood because of blisters and Sergio Garcia, who was feeling fatigued following an illness last week.
But it was a move that paid off as the defending champions reduced the American lead in Valhalla.
"It was a much better morning," said Faldo, who is hoping to lead Europe to their fourth straight Ryder Cup victory. "The United States had their day but we are here in good spirits.
"We had some fresh legs out there. This is a physical and mental battle and I believe with what we have seen that you need to give guys a rest.
"We came off the road a bit and now we're back on it."
Wilson had missed all of Friday's play and he was thrown into the action with Stenson against the stellar duo of world number two Mickelson and rising star Kim.
The American pairing won a point and a half in their two matches on Friday and looked as if they would secure another point as they got off to a flying start.
But they crumbled from the 6th, going five over in their closing 11 holes.
The Europeans went in front for the first time at the 15th when Mickelson pushed his drive into the trees and Kim fired the approach into the water.
And Wilson sealed the point in some style, draining a 20-foot birdie putt at the 17th.
"We stayed patient on the front nine but it did not go our way," said Wilson. "And when it did we tried to put the pressure on."
In the first game of the day, Poulter and Rose continued their winning partnership to make up for their collapse to the same opponents in Friday's foursomes.
Mickelson and Kim struggled after a fine start to their foursomes match
Poulter and Rose made a fine start, going 5 up after seven holes as their opponents struggled to find any kind of form.
But they let their lead slip - Cink and Campbell reducing the lead to two at the 13th.
Poulter restored order with a 15ft par putt at the 14th to win the hole and when Cink found water at the next, the match was as good as over, the Americans conceding when Poulter's approach landed 12ft from the hole.
"There was a lot of unfinished business from Friday," said Poulter. "We feel that this is a strong partnership in the foursomes and today was flawless golf."
Jimenez and McDowell were 2 up after seven in their match against the in-form pairing of Hunter Mahan and Justin Leonard.
But the American duo, who had won both of their matches on Friday, fought back and they went 1 up when Leonard sunk a long putt to win the 17th.
However, they could do no better than a closing par and Jimenez splashed out of a greenside bunker to four feet, from where his partner made no mistake.
Europe, who need 14 points to retain the trophy, will hope to further reduce the deficit in the afternoon fourballs while the hosts will seek to take a lead into Sunday's singles.
