Make it 20 wins this season for Kyle Busch, NASCAR's dominant workhorse. Overcoming his recent bad luck that has virtually ended his chances at a Sprint Cup championship, Busch returned to his familiar spot in the Nationwide Series on Friday night, cruising to a win in the soggy, wreck-filled Dollar General 300. The victory was the ninth for the 23-year-old Busch in NASCAR's second-tier series. He has won eight Cup races and three more in the Craftsman Truck Series.
