Young golfer Webb Simpson made a furious charge Sunday to win the U.S. Open, grabbing his fist major tournament victory.

Simpson had started the day four shots back of the lead but used a stretch where he carded four birdies in five holes midway through the final round to get to the top of the leaderboard.

Simpson shot a 68 Sunday to end the tournament at 1-over.

Surprisingly, that score was good enough to win as all the golfers struggled on the slick greens of San Francisco's Olympic Club and no one scored under par.

"It was a cool day. I had peace all day," said Webb, 26. "I prayed more the last three holes than I did all my life."

Jim Furyk and Graeme McDowell were tied for the lead coming into play Sunday.
