Brad Keselowski won his third race of the season by taking Saturday's Quaker State 400 at Kentucky Speedway. Keselowski was in a backup car after wrecking his primary vehicle in Friday's practice. The Penske Racing driver was able to hold off Kasey Kahne by four-and-a-half seconds down the stretch. Denny Hamlin finished third followed by Hendrick Motorsports drivers Dale Earnhardt Jr., Jeff Gordon and Jimmie Johnson. Kyle Busch finished 10th after winning last year's inaugural Sprint Cup event at Kentucky. Keselowski's three wins are the most in the series so far this season. He won in March at Bristol and May at Talladega.
