Because of rain wiping out practice and qualifying, the starting grid for the Cup Series race was determined by metric scores.

Ty Dillon and Ty Gibbs will race each other for the NASCAR In-Season Challenge's $1 million prize next week.

Gibbs finished fifth and surged ahead of Tyler Reddick on the final two restarts, while Dillon's ability to get the free pass on the final caution allowed him to stay ahead of John Hunter Nemechek.
