Denny Hamlin goes for the weekend sweep, while Kevin Harvick seeks to clinch the regular-season title Sunday at Dover International Speedway.

This weekend marks the third Cup doubleheader weekend this season. Hamlin and Harvick split the Pocono weekend, each winning once. Harvick swept the Michigan weekend.

He clinches the regular-season title if he is 61 points ahead of second place in the standings after Sunday’s race. Harvick enters the race 100 points ahead of Hamlin, who is second.

Jimmie Johnson enters the Sunday Cup race at Dover in what would be the final playoff spot. He pushed Byron out of that spot after Saturday’s race. Johnson leads Byron by three points. Erik Jones is 22 points behind Johnson.
