Doha, Qatar (My Sportsbook) - Alvaro Quiros closed with a three-under 69 in the final round Sunday to win the Qatar Masters by three shots.

Quiros, who held the third-round lead by a stroke, birdied two of his last three holes after a bogey at the 15th dropped him into a tie for the lead with Henrik Stenson. Quiros secured his third European Tour victory at 19-under-par 269.

Stenson, mounting a charge with an eagle at the 10th and a birdie at the 15th, couldn't muster enough. The 2006 champion bogeyed the last and shot a 68 to share second place with Louis Oosthuizen at 16-under 272.

Oosthuizen, who also shared runner-up status behind Paul Casey at last week's Abu Dhabi Championship, had a 71.

Damien McGrane (67) took fourth place at 13-under 275, while Miguel Angel Jimenez (69) and Maarten Lafeber (72) shared fifth at 12-under 276.

Sergio Garcia (277), Aaron Baddeley (278), 2007 winner Retief Goosen (280), two-time champion Adam Scott (280), Lee Westwood (281) and 2005 winner Ernie Els (282) were among the top players who failed to mount a serious challenge on Sunday.

Stenson took a one-shot lead with an eagle at the 10th hole. But Quiros and Oosthuizen -- playing behind Stenson in the last group -- birdied No. 10 to pull even at 16-under par.

The three-way tie for the lead was broken when Quiros collected back-to-back birdies at the 12th and 13th, taking a two-shot advantage. Oosthuizen dropped back with a bogey, but Stenson birdied the 15th to move within one.

Then things got hairy for Quiros.

He knocked his approach shot into the water at the 15th, holing a 15-foot putt just to save bogey and drop into a tie with Stenson for the lead. But he recovered admirably, collecting birdies at the next two holes to take a two- shot lead.

By then, a third victory in the last three seasons was all but assured for the 26-year-old Spaniard. His three-shot winning margin was secured by Stenson's closing bogey at the 18th.

Quiros, who set the tournament's 54-hole scoring record, fell just one stroke shy of matching the 72-hole mark. It was his second victory in 15 weeks, following his win at the Portugal Masters on October 19.

"The best (part) of these wins is how I have fought the last round," said Quiros. "I wasn't hitting the ball well. My strength was more in my mind than in my golf game."

For Stenson, ranked No. 11 in the world and unable to ultimately get it done down the stretch on Sunday, it marked his fifth straight top-seven finish in Qatar.

"It was a good day. [Quiros] obviously kicked in some good birdies in the end," said Stenson. "I'm still happy with my performance today. It's been another good week in Qatar."
