Kevin Harvick is now 2 for 2 at Speedweeks after winning the first Daytona 500 qualifying race.
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
