AVONDALE, Ariz. --
"This is awesome," said Harvick, who now holds the record for most Cup victories at PIR with five. "What a race car."
Harvick led 224 of the race's 312 laps around the one-mile oval, and he continually kept Earnhardt at bay on several restarts following caution periods.
"We didn't have enough race car all day long" to catch Harvick, Earnhardt said, adding that Harvick "feels good and confident about what he's doing here."
This was the second race in the Cup series' 36-race season. The series moves to Las Vegas Motor Speedway next Sunday.
