Karlsson's recovery complete after Qatar Masters success

After becoming the first Swedish player to be named European No 1 in 2008, Karlsson was sidelined for four months last year suffering from blurred vision caused by fluid behind the retina in his left eye.

But at Doha Golf Club the 40-year-old was back to the best which saw him win twice in 2008 to ensure a second successive Ryder Cup appearance.

Karlsson produced the round of the week to win with a stylish bogey-free seven-under-par final round.

"The focus this year was to come back and start to put together good rounds and a then a string of good rounds and then you never know what's going to happen," said Karlsson, following his 10th career title.

"That's the thing I am most happy with. It's not really the win, it's fantastic to win, but to play four really good rounds together, that's the most satisfying."

After beginning the day two shots adrift, Karlsson shared a one-shot lead with Bradley Dredge at the turn, but as the Welshman's challenge faltered, Lee Westwood mounted a late bid with a run of four birdies in five holes.

The European No 1 trailed his playing partner by one shot with four holes to play, but the world No 4 was becoming increasingly frustrated with a new driver after cracking the face of his previous club during the third round.

And Westwood's challenge came to an abrupt halt with a three-putt bogey with two holes to play before Karlsson ensured his first victory since the 2008 Alfred Dunhill Links Championship with back-to-back birdies.

Big-hitting Spaniard Alvaro Quiros took advantage of Westwood's demise with a hat-trick of late birdies to claim second in an admirable title defence.

"I played very good and I had my chances," he said.

Yorkshire pair Danny Willett (76 68 71 71) and Simon Dyson (73 71 70 72) finished 13 shots adrift of the leader.
