Phil Mickelson's brilliant victory in the Open Championship has taken the American back to second in the world rankings for the first time since September 2010.

Mickelson carded a final round of 66 at Muirfield to win the Claret Jug for the first time and a fifth major title of his career.

The 43-year-old moves from fifth to second in the latest standings, with Rory McIlroy dropping to third and Justin Rose falling from third to fifth after both missed the cut. Runner-up Henrik Stenson climbs from 30th to 20th.

Adam Scott remains fourth despite a share of third place with Lee Westwood and Ian Poulter, who move to 10th and 14th respectively. 

After his Muirfield success, Mickelson is now targeting a career Grand Slam. The US Open has somehow escaped his grasp, with last month's second place to Justin Rose at Merion extending his own record of runners-up finishes to six.

He explained: "I think that if I'm able to win the US Open and complete the career Grand Slam, I think that that's the sign of the complete great player.

"I'm a leg away. And it's been a tough leg for me! 

Mickelson did not complete the thought, but his caddie Jim Mackay has no doubt the left-hander will never stop trying to win.

"He looks forward. He works hard," Mackay said. "How many people are going to build a practice facility in his yard post-40? He wants it.

"He's stronger than he's ever been, he's fitter than he's ever been, and he's hungrier than he's ever been. And you can't underestimate how much he wants to compete and do well.

"When he's 60-something years old he's going to be on the putting green at Augusta thinking he has a chance. That's just how he is built."
