Electrical gremlins have ruined Denny Hamlin's run in the Tums Fast Relief 500 at the Martinsville Speedway. His championship dreams are probably also over for another season. Hamlin's Toyota began losing power and finally stopped on the frontstretch on lap 393. It ruins what had been a valiant drive for the Joe Gibbs Racing driver, who twice raced from deep in the pack after speeding penalties into the top-five.
Championship hopeful Jimmie Johnson grabbed the lead under the caution flag for Hamlin's stall, with Clint Bowyer - who has led the most circuits - Kyle Busch, Kasey Kahne, and Jeff Gordon completing the top-five.
Dale Earnhardt Jr. runs sixth in his return to the Sprint Cup Series from his break to heal from his concussions. Brian Vickers is seventh, Kevin Harvick eighth, point leader Brad Keselowski runs ninth, and Sam Hornish Jr. completes the top-10 with 100 laps remaining in the 500-lapper.
