Jordan Spieth says his United States team-mates still believe they can reclaim the Ryder Cup despite trailing 10-6 going into the final day.
Spieth and fellow rookie Patrick Reed saw their winning run at the competition come to an end in Saturday's foursomes, as they could only halve their match with Martin Kaymer and Justin Rose.
The two debutants had been in fine form at Gleneagles but they were thwarted at the last as Rose holed a birdie putt to deny the US a single victory in Saturday's second session.
Europe now lead by the same scoreline they trailed at Medinah two years ago before a stunning final-day comeback - something Spieth feels the US are capable of emulating.
Asked about the possibility of a similar feat, he responded: "Yeah, everyone in our team room believes that we can do that.
"We all believe that it's possible. Brookline was 10-6, Medinah was 10-6 the other way. Hopefully we get some good pairings and some guys out early to go and make a move.
"We were able to in both mornings the last two days - really, really gain some momentum by seeing red on the board early.
"I think that's going to be key tomorrow, but we're ready."
Spieth's confidence certainly looks to have convinced US captain Tom Watson, with the 21-year-old Texan first out in the singles on Sunday as he goes up against Graeme McDowell.
Spieth and Reed's tussle with Rose and Kaymer remained finely poised throughout as the two sides were at all-square going into the final two holes.
Reed spoke of his frustration at not being able to repeat their fourballs performance from earlier in the day, where the US rookies had seen off Kaymer and Thomas Bjorn 5 and 3.
"This morning we started out great. [It] seemed like we had the most control and command of our golf ball and it felt like we were making a lot of putts," he added.
"This afternoon was just sloppy, on both sides. Justin even said it was sloppy on their side like it was sloppy on ours.
"It was one of those matches that...you know, it was tough. It was one of those matches hopefully you were able to grind out and get the full point.
"Unfortunately, we weren't able to get the full point but at least we were able to put some more points on the board with a half."
