Kyle Busch led from start to finish, usually by plenty, and ended an eight-race winless streak in the NASCAR Nationwide Series with his fifth career victory at Richmond International Raceway.
Busch started on the pole, routinely built leads of several seconds and was never really challenged Friday night.
Kevin Harvick appeared to be closing in on him with about 40 laps to go, then began to fade again.
The sixth caution bunched the field for a restart with 18 laps to go, and Busch again made quick work of his competition, cruising to his record-extending 67th victory in the series.
It was the fourth victory of the season for Busch, but first since May 31 at Dover.
Nationwide Series points leader Chase Elliott overtook Harvick to claim second.
