Denny Hamlin, who earned the Busch Light Pole Award on Saturday, fired to the lead on the initial start. All four Joe Gibbs Racing Toyotas ran 1-2-3-4 after qualifying that way until they made pit stops at Lap 36 under green. After the cycle was complete, Hamlin returned to the lead. Ty Gibbs, who ran second before service, was penalized for speeding and returned to serve a pass-through.
After starting sixth, Kyle Larson dropped eight positions during the opening stint and was the first driver to dart for pit road. He spent 26 seconds stopped in his stall for massive adjustments and ultimately fell a lap down once the pit cycle completed.

The first caution came out at Lap 45, when Zane Smith spun from 28th after an apparent tire issue. He clipped the Turn 4 outside wall with his right-rear fender but continued after visiting pit road for repairs.
Seven lead-lap cars stayed out, including Briscoe and Bell. Hamlin and his 23XI Racing drivers Tyler Reddick and Bubba Wallace were the first drivers to pit road, and they rejoined the field ninth through 11th. Larson also stayed out, allowing him to wave around to the lead lap.
With three laps to go in the stage, Hamlin spun by himself in Turns 3 and 4, coming to rest on the apron after keeping his No. 11 Toyota off the wall. The race remained green and Hamlin stayed on the lead lap, finishing the frame 28th. He led 39 of the first 80 laps.
