“It is one of those things,” he said with a shrug. “I feel like I should have won the U.S. Open. But there are plenty of top players who have led big events with 18 holes to play and not won. So I’m hardly unique in that. I just wasn’t aggressive enough on Sunday. I had played three rounds of World No. 1 golf. And on the last day I made a good par at the first. Then, at the second—a par 4 I could have driven—I laid up. I was trying to maintain my lead instead of trying to win the tournament. When I am in that position again, I will go out there to win instead of protecting my lead.”
