Phil Mickelson and Rickie Fowler came from behind to beat Rory McIlroy and Andy Sullivan 1 up to seal the first whitewash since 1981.
Lee Westwood said: “I will take responsibility. I played poorly and Thomas played well. He made some putts when we needed to.
“You try to put a bit of pressure on, you don’t want to be giving holes away. I hit a couple of wild drives early on and you cant afford to do that. It’s a tough game to play and you want to get momentum.
“Anything can happen in the Ryder Cup.”
