Jay Coffin of the Golf Channel reports — As NBC’s Bob Costas was interviewing newly crowned champion Webb Simpson a mysterious man, wearing a Union Jack hat, started crowing like a bird. Costas and Simpson were looking mysteriously at the man when U.S. Golf Association chief Mike Davis jumped into the picture and forcefully pulled the man out of the way.

A raucous fan, wearing a wacky Union Jack cap, disrupted Webb Simpson's trophy ceremony at the US Open with squawking bird calls. Msnbc's Willie Geist reports.

Simpson saved par on the hilly 18th hole with a chip from the rough to about 4 feet, closing with a 2-under 68 to hold off Graeme McDowell and Michael Thompson in a foggy final round at The Olympic Club on Sunday. Simpson finished at 1-over 281.

Michael Thompson and Graeme McDowell were a shot back.
