Qualifying
Kyle Larson was awarded the pole for the race as determined by competition-based formula.

Race
Kyle Larson started on the pole for the race. Four cars (#10, #19, #24, #66) dropped to the rear for multiple inspection failures. Larson won stage one. Following an incident with Joey Gase only five laps into the run, most cars pitted with the four Hendrick Motorsports cars choosing to stay out. The Hendrick cars thought they were on the outside of the fuel window, but due to an extended caution the cars that pitted were able to make it to stage two. This forced the Hendrick cars to pit under green, forcing them a lap down. Chase Elliott was able to un-lap himself, and William Byron earned the lucky dog pass. Denny Hamlin won stage two and went on to win the race, beating Elliott by 0.442 seconds.
