"We finally get one, we finally get one,'' Busch said. "It means a lot.'' Busch celebrated the win and then joined 19 other drivers in retreating to their motorhomes to rest up for the Nextel Cup event scheduled about nine hours later -- a rare day-night doubleheader created when rain washed out the Busch race Friday night.

The 20 Cup regulars were facing a long day of 650 miles of racing. Busch dominated much of the 102-lap morning event, taking the lead with a risky maneuver leaving pit road early and then staying out front pretty much the rest of the way.
