Jimmie Johnson scored his second NASCAR Sprint Cup victory in as many weeks at Dover, holding off Brad Keselowski in a late-race restart.

Hendrick Chevrolet star Johnson dominated the second half of the race, having wrested the lead from Matt Kenseth’s Joe Gibbs-run Toyota on lap 180.

Clint Bowyer attempted a bold two-tyre strategy at the final round of pitstops to briefly grab the lead, but Johnson dispatched him within seconds of the restart and was never again headed.

A final yellow flag, due to Casey Mears’ tyre falling to pieces inside the last 10 laps, meant a four-lap shoot-out to the finish, but Johnson kept his cool once more.

Poleman Brad Keselowski finished second in his Penske Ford, having closed the gap to Johnson in the penultimate stint, but he was unable to do anything about the six-time champion in the final reckoning.

Kenseth finished third, escaping a hairy moment when Bowyer got into the back of him at the final restart.

Denny Hamlin finished fifth, despite an early pitlane speeding penalty.

The race was red flagged twice, once to clean debris from a crash involving Roush-Fenway duo Greg Biffle and Ricky Stenhouse Jr, which was started by AJ Allmendinger, and a second time when the track came apart at Turn 2.

Ryan Newman tore up part of the concrete race surface into the path of Jamie McMurray, whose car hit the wall after he’d slammed into the debris.

The track required repairing, which meant a lengthy delay, but no further issues were encountered after the restart.
