Webb Simpson refused to think of himself as a U.S. Open champion until he sat with his nervous wife in a quiet corner of the locker room Sunday, staring in disbelief at a television as Jim Furyk and Graeme McDowell tried to catch him.He was up against a pair of major champions. He was at The Olympic Club, where the wrong guy always wins a U.S. Open.Simpson should have known now how this would end.He did his part with four birdies in a five-hole stretch around the turn, and a tough par from the collar of the 18th green for a 2-under 68. It was enough to capture his first major when Furyk bogeyed two of his last three holes, and McDowell couldn't recover from a bad start and too many tee shots in the rough."Oh, wow," Simpson said when McDowell's 25-foot birdie putt to force a playoff stayed left of the cup.
