The Joe Gibbs Racing cars were among the first to organize a draft. Lined up with Erik Jones leading the way, Martin Truex Jr., Busch and Hamlin all closely followed. At the time of their run, all four drivers jumped into the top 10 on the leaderboard.
Others who formed a draft were three of the four Stewart-Haas Racing cars, led by Daniel Suarez. Tucked behind him were Aric Almirola, and Clint Bowyer with Matt DiBenedetto getting a tow from a few car lengths behind.
Drafting picked up late in the session when a large pack of Chevrolet drivers took to the track. The group was led by Hemric and consisted of Wallace, Ty Dillon, Austin Dillon, Ryan Preece, Buescher, and William Byron. The three Team Penske cars also drafted together.
