Jimmie Johnson - no surprise - has assumed command of the AAA 400 at Dover International Speedway. Johnson took the lead six laps from the halfway point and has dominanated the 100 laps since. The five-time defending Sprint Cup champion is seeking his seventh triumph at the Monster Mile and a jumpstart to what, through two races, had been a stalled pursuit of his sixth-straight championship.
Kasey Kahne is shown second, ahead of Matt Kenseth, Kurt Busch, and Marcos Ambrose. The top-10 is filled out by A.J. Allmendinger, Greg Biffle, Kyle Busch, Clint Bowyer, and Kevin Harvick.
Carl Edwards, who led much of the first half of the race, sped on pit road under green-flag conditions at lap 249 and is currently shown 21st, one lap of the pace. Brad Keselowski, who spent most of the race in the top-10, has lost his power steering and also runs off the lead-lap.
The day-long struggle by Tony Stewart has been joined by a bad break for Dale Earnhardt Jr., who had a flat right-front tire. Both Chasers are two laps down.
