Phil Mickelson has replaced Rory McIlroy as World Number 2 following his first Open Championship win at Muirfield yesterday.

The American carded a sensational final round of 66 to finish the only player below-par on 3 under.

The Open win was the 43-year-old's fifth Major of his career. 

McIlroy's poor form this year saw him miss the cut at a Major again.
