“It was a great week,” said Kaymer. “It was our best result we've ever had, tied second. I think we were not the favourites coming into the week, but we showed again that we are good players and we play well together.
“I look forward to the next few years, because if I could have played a little better today, I think we would have had a good chance to win.”
Ireland looked to be back on track after their poor start when McIlroy stuck his approach to two feet at the third and sunk a ten-foot birdie putt two holes later.
But he and Graeme McDowell three-putted again at the sixth, and although McIlroy chipped in at the tenth, he missed from inside three feet for a second time at the 12th to effectively end their challenge.
A level par 72 left them level with Australia, the Netherlands and Scotland on 21 under par.
“We just didn't have it out there today,” said McDowell. “We had no mojo, we didn't make anything.
“We knew what we had to do today. Our target was to go and shoot four under par and that's exactly what we needed to do. We just couldn't get it done.
“We’re disappointed, of course, but this is a high quality golf tournament. The USA have played fantastic, England have played phenomenally well, and that was the high standard that we had to live up to today and we just didn't do it.”
Rose and Poulter were the stars of the day but an eight-shot overnight deficit proved just too much. The highlights of their round were Poulter’s 12-foot eagle putt on the 16th and Rose’s 20-foot birdie at the last.
“We as Team England were a little subdued last night,” said Poulter. “I don't think either of us were much company. We stayed in our own rooms and kind of rightly so.
“I think yesterday was disappointing to shoot four under par in fourball, and to go and shoot nine under par in foursomes is crazy.
“We bizarrely shoot nine under today and actually leave shots on the golf course, which sounds very silly to say, but it's the fact.”
Rose added: “I felt like today was a bit about coming out and playing for pride. You always have pride when you are playing for your country, but it was about restoring in individual pride for ourselves.
“Both fourball days were uncharacteristic for us, and today was fun. We gelled and finally got the right rhythm and right intensity and I think when we do get that, we match up really, really well."
Rose joked: “I think the secret today was we dressed a little better. We dressed like the flag - we looked at each other this morning and said ‘I feel good today, should have worn this all week’. Should we represent England in a couple of years, this will be the look."
