Jamie McMurray has snapped an 86-race winless streak with a victory at Talladega Superspeedway. Three-time defending series champion Jimmie Johnson is being credited with an eighth-place finish - enough to likely wrap up a NASCAR record fourth consecutive title. The race ended under caution because of a last lap accident that sent Mark Martin's car flipping across the track. It was the second harrowing accident in the final five laps.
