On his very first practice lap at Kentucky Speedway on Friday, Brad Keselowski wrecked his best car. What could have been a devastating blow, ended up being a curious blessing. Driving his backup, Keselowski raced to his series-leading third victory of the year Saturday night, grabbing the lead with 55 laps remaining and holding off all challengers in the NASCAR Sprint Cup race at Kentucky Speedway. "It wasn't the newest car we got, but it runs," Keselowski said. The 28-year-old from Rochester Hills, Mich., picked up his seventh win in his five years on the circuit. He won earlier this year at Bristol and Talladega. He gave all the credit for the latest victory to his team. "They put together a backup car from last year in 100-degree heat in one hour's time to get me back on the track," he marveled. Kasey Kahne rode a late surge to second place, 4.399 seconds back of the winner. Read more: http://espn.go.com/racing/nascar/cu...d-keselowski-pulls-away-win-kentucky-speedway
