RICHMOND, Va. -- Kevin Harvick's dominance in NASCAR's Busch Series has been so pronounced all season that even his racing competitors are starting to concede.

"They ought to just give him the trophy now," Greg Biffle said Friday night after Harvick won for the sixth time this season and the third consecutive time at Richmond.

Harvick led five times for 154 laps and will leave Richmond International Raceway with a 619-point lead over Carl Edwards and just seven races left on the schedule.

The lead is three more than the biggest season-ending point margin in series history, achieved when Jeff Green won the 2000 title by 616 points over Jason Keller.

That means Harvick could skip three of the races entirely and still have the lead, but the 2001 series champion said he's not looking for a reason to let up at all.  More
