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 doesn’t just have two wins in his last six starts, the Joe Gibbs Racing driver has five top-four finishes in his last seven starts. That type of consistency is hard to beat. And that has put him back atop these power rankings.
