TALLADEGA, Ala. (AP) -- 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. Ryan Newman's car sailed onto its roof and landed upside down in the grass, causing a red-flag delay of almost 13 minutes for Newman to be cut from the car.

That set up a two-lap shootout to the finish of what had otherwise been a quiet day of racing at Talladega.
