Doha, Qatar -- Spain's Alvaro Quiros shot 8-under-par 64 Saturday, giving him a one-stroke lead after the third round of the Qatar Masters golf tournament at Doha.

His 54 hole total, 16-under 200, matches the tournament record set by Scotland's Paul Lawrie in 1999.

Quiros sizzled from the start Saturday at the Doha golf club course, making birdies at three of the first four holes, and his bogey-free round included eight birdies in all.

"I'm very happy," said the 26-year-old Spaniard, the longest hitter on the European golf tour. "I worked hard last week and it looks like the scores are starting to come."

On Sunday, he seeks the third tournament title in his third season on the tour.

Overnight leader Louis Oosthuizen (69) of South Africa is alone in second place at 15-under-par 201, despite a double-bogey at the par-4 fifth hole.

Doha, Qatar -- Scot Andy Murray won his second straight Qatar Open Saturday, beating American Andy Roddick in straight sets.

The third-seeded Murray broke service in the first set and went on to win his ninth ATP title 6-4, 6-2.

Murray had eliminated Swiss star Roger Federer in the semifinals.

Roddick, who was seeded No. 4, was trying for his 27th singles title on the tour.

Doha, Qatar -- Returning champion Andy Murray turned on the after-burner and upset former world No. 1 Roger Federer in a semifinal Friday at the Qatar Open.

Another former No. 1, Andy Roddick, downed Gael Monfils in Friday's other tennis semifinal.

The Qatar Open, the ATP World Tour's season-opener, is a $1.11 million tuneup for the Australian Open.

Third-seeded Murray downed Federer for the fifth time in seven tries, coming from behind to defeat the second-seeded Swiss Federer 6-7 (6-8), 6-2, 6-2 in two hours and four minutes.

Fourth-seeded Roddick triumphed over the fifth-seeded Monfils, 7-6 (7-1), 3-6, 6-3. Monfils, the 2008 French Open semifinalist, had upset world No. 1 Rafael Nadal in straight sets during Thursday's quarterfinals.
