It will be a battle of the titans at Phoenix Raceway, as two Hendrick Motorsports drivers and two Joe Gibbs Racing drivers advanced into the Championship 4.
Denny Hamlin and Chase Briscoe were already locked in via wins at Las Vegas and Talladega, leaving two spots up for grabs at Martinsville. Christopher Bell entered the race with a large margin over the cutline, but only one point between himself and Kyle Larson.
