(AP) --
Kevin Harvick held off Greg Biffle over a four-lap sprint Thursday to win the first 150-mile Budweiser Duel. Harvick and Biffle also went 1-2 in last Saturday night's exhibition race.
The starting field for Sunday's season-opening Daytona 500 is set by the results from the pair of 60-lap qualifiers.
Danica Patrick started on the pole for the first race and simply needed to keep her car intact to hang on to her front row starting spot in the Daytona 500.
She raced a little at the start of the duel, then faded back in the field and wound up 17th out of 23 cars.
Denny Hamlin triggered a four-car accident with 7 laps remaining
Kyle Busch has won the second of Daytona's twin qualifying races by holding off a late challenge from Kasey Kahne.
Busch will join Kevin Harvick in the second row of the season-opening Daytona 500 on Sunday.
The two earned their starting spots by winning their respective 150-mile Budweiser Duel race on Thursday.
Kahne finished second behind Busch after failing to get close enough to attempt a race-winning pass. Third went to Austin Dillon, who earned a spot in his first Daytona 500.
Harvick won the first duel to make it 2 for 2 at Speedweeks. He also won last weekend's exhibition race.
The starting lineup for the Daytona 500 is set by the results of Thursday's races. Danica Patrick will be on the pole for the race.
