The rain continued through the afternoon at Darlington Raceway and also washed out qualifying for the NASCAR Winston Cup Series Mountain Dew Southern 500.
Qualifying for Saturday's scheduled Busch race will be determined by points standings, placing Ford Taurus drivers Greg Biffle and Jason Keller on the front row. There was more rain in the forecast Saturday.
"I'm just happy to be in the points lead when things like this happen and to be able to start up front," said Biffle, who leads Keller by 78 points.
Keller, a native of Greenville, is seeking his first victory at Darlington Raceway. In 18 starts here, his best finish is third.
"I have looked forward to going back to Darlington since I left in the spring," Keller said. "A victory at Darlington would mean more to me than winning at Daytona."
Jack Sprague will be in the second row in a Chevrolet Monte Carlo alongside Scott Wimmer in a Pontiac Grand Prix.
