The United States justified its status as odds-on favourite by staging a superb fightback to retain the Walker Cup at Royal Liverpool.
Trailing 7-5 overnight, the visitors won two-and-a-half points from the morning foursomes before claiming six of the first seven singles matches to secure victory with three matches still to finish.
Scotland's Sandy Scott enjoyed a superb 4&3 win over the previously unbeaten Brandon Wu, but defeats for Alex Fitzpatrick, Euan Walker, Caolan Rafferty, Harry Hall, Conor Purcell and Thomas Plumb condemned the home side to defeat.
The previous American victory away from home came in 2007 with a team which included future major champions Dustin Johnson and Webb Simpson and PGA Tour winners Rickie Fowler, Billy Horschel, Kyle Stanley and Chris Kirk.
Rory McIlroy and Danny Willett were among the Great Britain and Ireland team which lost by a single point at Royal County Down.
