Former European number one fires round of 65 to triumph in Doha.

Robert Karlsson claimed his first title since the 2008 Alfred Dunhill Links Championship with victory at the Qatar Masters in Doha.

Although world number nine Casey (right) admitted before the tournament that the course at Doha Golf Club didn’t suit him visually, he seemed to be well focused as he stormed through the field with a near-flawless third round of 66 (-6).

“I think it's my best round around this golf course in four years of trying, so I can't say anything bad about it,” smiled Casey after a round of seven birdies was spoiled by a bogey on the notoriously difficult fifteenth hole. “Three times I have missed the cut so to be sitting here at the top of the leaderboard makes me smile.”

Karlsson missed four months of the 2009 season after suffering from blurred vision caused by fluid behind the retina in his left eye.

I am really happy to be back playing well, it is the first time I have played really well for a long time and the way I finished off today was very satisfying.
