Truex drove down and passed Busch on Lap 69, and drove on to win the first stage. Caution #2 flew moments after on Lap 81 for the conclusion of the stage. Under the caution,Denny Hamlin andKyle Larson were sent to the tail-end of the field on the following restart for speeding on pit road.

Four laps after the Lap 167 restart, Truex took back the lead and set sail from the field.
