GLADEVILLE, Tenn. — Brad Keselowski raced to his first Nationwide Series victory tonight, passing Clint Bowyer with six laps to go and easily holding off his closest rivals at Nashville Superspeedway.

Kyle Busch, racing in the second of three NASCAR races in a historic weekend triple, finished 20th, three laps down. A green flag pit stop with 52 laps to go bounced him from the top five to two laps down.

Keselowski, driving for Dale Earnhardt Jr., became the seventh first-time winner in 15 Nationwide races at Nashville Superspeedway. David Stremme rallied to finish second, followed by David Reutimann and Bowyer.

Busch's setback came 24 hours after his second-place finish in the Craftsman Truck Series race at Texas Motor Speedway.

By starting tomorrow at Pocono, the Sprint Cup Series leader will become the first driver to compete in all of NASCAR's top three series at different tracks on the same weekend. Busch will start in a backup car at the tail of the field, the result of a crash earlier today that destroyed his primary car during practice.
