Cole Custer, driver of the No. 00 Haas Automation Ford Mustang for Stewart-Haas Racing:           

“The car didn’t start our great, but we worked hard to make our Haas Automation Ford Mustang better throughout the race. We had a top-10 car, just had back luck on pit strategy. Nothing we could do about it.”
