With a 20th-place finish, Dillon -- the No. 32 and final seed in the In-Season Challenge -- advanced to the final round of the tournament, where he will race Gibbs (who won his matchup against Tyler Reddick) for a $1 million prize in next weekend's Brickyard 400 at Indianapolis.

Hamlin won in the No. 11 Toyota for the second straight time at Dover to add to wins this season at Martinsville, Darlington, and Michigan.

Denny Hamlin certainly had to earn it at Dover Motor Speedway on Sunday. After a one-hour rain delay, he had to face two hard-charging teammates in the closing laps, beating both Christopher Bell and later Chase Briscoe to capture the win.
