Webb Simpson has moved to a career high fifth in the world rankings after his victory at the Olympic Club on Sunday.
The American fired home a final round 68 to claim his maiden major title as he finished one stroke ahead of Michael Thompson and the champion of 2010 Graeme McDowell.
Simpson, 26, was one of the most consistent performers on the tour last season and finally proved his considerable talent on a course that proved too much for the likes of Luke Donald and Rory McIlroy.
The duo remain the number one and two in the world, while Lee Westwood is still just above Tiger Woods who also showed signs of his best form in San Francisco before rounds of 75 and 73 saw him slip away from the leaders.
Despite winning his maiden major, it seems he may miss next months Open Championship as his wife is due to give birth to their second child in sex weeks time.
“I don’t think he is going to play the British Open just in case I go into labour,” revealed Dowd Simpson. “It would make Webb too nervous.”
