United States' Jordan Spieth believes his partnership with fellow rookie Patrick Reed flourished because of their inexperience.
The pair thrashed European talisman Ian Poulter and Scot Stephen Gallacher 5&4 to give the Americans their first point of the morning fourballs.
As they were making their first appearance neither was burdened by recent history which has seen their country lose seven of the last nine and, more significantly, they were unaffected by the collapse at Medinah two years ago.
"We got a pairing we liked yesterday. No battle scars," said Spieth.
"I think everybody on the team wants Poulter and we were able to have him first.
"I missed a couple short putts, Patrick made a couple and then all of a sudden the hole looked bigger and we both kind of fed off each other nicely.
"Most of our birdies were on different holes but, at the same time, on holes where we made birdie the other was in good position any way.
"We just hit a lot of greens together: one putt may miss, the other may go in but when you get a lot of looks from 20 feet and in, especially with a guy who putts as well as Patrick does, we're going to end up filling it up.
"Hopefully we get out tomorrow morning with the same idea. I mean, we've got all the confidence in the world."
After their brilliant performance it was something of a surprise to see them rested for the foursomes and the players made their feelings known to their captain,
"They were very upset with me for not playing them this afternoon," said Tom Watson.
"I said 'I know you're going to be mad at me, but you'll be playing tomorrow for sure'."
Reed, who after winning the WGC-Cadillac Championship in March declared himself to be one of the top-five players in the world, said they had to accept Watson's decision.
"I felt like in alternate-shot, him (Spieth) and I would have been great to go back out and take the momentum of what we just had done," said the 24-year-old, who admitted he could hardly breathe on the first tee.
"But at the end of the day captain Watson picks pairings for a reason. He decides to put you in certain spots for a reason.
"I was over it when he told us we weren't (playing)."
