Denny Hamlin and Kevin Harvick make gains to their wins total in the doubleheader Drydene 311 this weekend at Dover International Speedway.

The NASCAR Cup Series have their last doubleheader weekend at Dover International Speedway this weekend. Before the weekend, there are three races left in the regular season, with two races at Dover, and the last race of the season at Daytona International Speedway next weekend. For drivers on the cusp of the playoff bubble, many look to Dover as the place to secure their spot. However, after Dover, the playoff competition is tighter than anyone expected.
