Vilamoura, Portugal (My Sportsbook) - Alvaro Quiros shot a four-under 68 on Sunday to win the Portugal Masters by three shots for his second career European Tour title.

Quiros, a 25-year-old from Spain, made back-to-back birdies to close out his final round at Oceanico Victoria Golf Course and finish the tournament at 19- under-par 269.

Former British Open champion Paul Lawrie shot a five-under 67 and took second place at 16-under 272, while Robert Karlsson (71), Ross Fisher (71) and 2007 champion Steve Webster (68) shared third at 15-under 273.

The Order of Merit leader Karlsson, seeking a record-tying third straight win, was tied for the lead with Fisher and Quiros when the third round was suspended Saturday afternoon because of a storm.

But Quiros held the lead by himself after finishing off a third-round 67 on Sunday morning, and he managed to fend off Karlsson and Fisher to keep it.

Quiros took a two-shot lead with a short birdie putt at No. 8 when Karlsson made a bogey at the same hole. But the Spaniard's advantage was just one stroke around the turn when Fisher made a birdie.

A birdie-bogey outcome at the 10th and 11th holes kept Quiros' lead at one, and he wouldn't get it back to two shots until he rolled in a 12-foot birdie putt at the 17th to all but seal the victory.

Quiros closed with a five-foot birdie putt at the 18th for his three-shot win.

The victory comes near the end of a difficult season that has seen Quiros miss the cut 12 times. But he now has two consecutive top-five finishes, including a tie for fourth place at last week's Madrid Masters.

"Well, you can imagine how happy I am right now," said Quiros. "It's been a really tough year for me. This is like a little help."

Quiros ended the final round with six birdies and two bogeys. He opened with an amazing 50-foot birdie putt on the first hole, followed that with a bogey, but got right back on track with another birdie at No. 3.

It was his near-flawless play the rest of the way, however, that guided him to his first win since last season's Alfred Dunhill Championship.

Lawrie, meanwhile, earned his best finish in three years and only his second top-10 in 24 starts this season. He has missed about a third of the cuts this season.

"It feels great to be competitive again," said the 1999 British Open champ.

Karlsson, now nearly 300,000 euros ahead of Padraig Harrington for the top spot on the European Tour money list, admitted he didn't play well Sunday. He had five birdies and four bogeys, the last coming at No. 17 when he hit into the water.

"I had a chance up until the 17th where I hit a poor shot," said Karlsson, "but it's been one of those weeks where I haven't hit the ball great, and when it's been in between it's just been a bit, and I've had a few indifferent shots."
