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.

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.
