Less than five minutes into the second session, Ricky Stenhouse spun in Turn 3 and hit the wall, which did some significant damage to his No. 47 Chevrolet.
With under five minutes remaining in the session, Joey Logano spun in Turn 3 after his left-rear tire went down and skated up the track and into the wall. Logano’s No. 22 Ford took a lot of rear-end damage.
“I drove off into the corner and I could feel (the tire) shaking and I knew it was bad,” Logano said. “We’ll have to come from the rear (of the field) but we’ll be alright. We’ll fight through it. I think we were pretty decent with lap times before that.”
Kyle Busch was among the first to take to the track in Group A and posted the fastest average lap of the session (175.415 mph).

After about 15 minutes, Cody Ware spun in Turn 2 but did not appear to hit the wall and was able to drive back to pit road.
Just before the end of the session, Ryan Blaney had a left-rear tire go down and spun off Turn 4. A minute later, Hamlin slowed on the frontstretch with flat left-rear as well.
