Chase Briscoe started at the rear of the field due to electrical issues, so Austin Cindric started on pole. On the second lap, Tyler Reddick slid on the frontstretch and Justin Allgaier followed, causing Harrison Burton and Brandon Jones to wreck behind them. This wreck caused Jones to be eliminated from the playoffs. On lap 22, John Hunter Nemechek spun Mike Harmon and brought out the second caution. Allgaier took the lead and won Stage 1.

Allgaier continued his lead to win Stage 2. Briscoe took the lead afterwards and dominated. Cole Custer, Michael Annett, and Justin Haley stayed out late in the pit cycle, which proved to be beneficial when Dillon Bassett caused a caution when he spun entering pit road. Allgaier got the free pass, while Briscoe and Cindric took the wave-around, causing only six cars to be on the lead lap during the restart.

Custer sped past Allgaier on the restart, then remained in the lead after the last one caused by Stephen Leicht, Matt Mills, and Ray Black Jr. being involved in an accident with seven laps left. Custer held off Allgaier to take the race win. With Jones eliminated in the opening laps, Nemechek needed Annett to struggle in order to pass him in points while Haley and Ryan Sieg needed to win the race to advance. Since Nemechek didn't gain 10 points more than Annett, he was eliminated from the playoffs alongside Haley and Sieg.
