JOLIET, Ill. — Just when it appeared Kyle Busch couldn't be any stronger in a Nationwide Series race, he broke the record for most laps led on a 1.5-mile track in a Nationwide race in winning the Dollar General 300 race at Chicagoland Speedway on Saturday. Starting from the pole, Busch went on to lead 195 of the event's 200 laps, eclipsing the record of 194 laps led the late Dale Earnhardt set at Charlotte in 1986. "It was just a great day with a phenomenal race car," said Busch, who earned his 10th win in 20 Nationwide races this season, tied for second-most wins in a single season on NASCAR'sjunior circuit.
