AVONDALE, Ariz. -- Kevin Harvick made it a weekend sweep Saturday at Phoenix International Raceway, winning the Subway Fresh 500 with a late dash in the NASCAR Nextel Cup Series race.

The victory was Harvick's third straight. He won the Busch Series race Friday and the Busch race April 15 in Gladeville, Tenn.

With 30 laps left, it looked as if the race would be won by either Greg Biffle or Tony Stewart, who were running one-two. But Harvick was plotting his course when he was about four seconds behind Biffle.

Harvick began making a move with 20 laps left. After getting around Stewart for second on lap 290, Harvick pushed his Richard Childress Chevrolet around Biffle four laps later in front of an estimated crowd of 75,000.

Matt Kenseth, who finished third in a Roush Racing Ford, moved into first in the Cup series standings.

Biffle finished 15th after running out of gas with two laps left.

Stewart's runner-up finish came after he started last despite qualifying third. NASCAR forced his No. 20 Joe Gibbs Racing Chevrolet to the back because the car did not start the race on its qualifying tires, as rules mandate.

Harvick's victory ended a two-race winning streak at the track by Las Vegas' Busch brothers. Kurt won the April race a year ago, and Kyle won the Phoenix Cup race in November.

Kurt Busch had problems Saturday but finished 11th to move to 17th in the standings.

Kyle Busch had a night he would like to forget.

Kyle, who started from the pole, was leading on lap 55 when a minor crash brought out the caution flag. But he lost the lead after being penalized for going too fast when he entered pit road. He had to drive through pit road a second time and restarted the race 39th.

Then it got worse for the driver of the No. 5 Hendrick Motorsports Chevrolet.

On lap 99, Kyle collided with Casey Mears a split second before six other cars were collected in a crash on the fourth turn.

The yellow flag was out for a few seconds when NASCAR decided to stop the race with a red flag. That was about the time Kyle ran into Mears in an apparent retaliation for the initial contact with Mears.

Kyle fell 45 laps off the pace, and when the car returned to the track, NASCAR sent him to pit road for a five-lap penalty.

He finished 36th and dropped from seventh to ninth in the standings.
