Chastain was the first driver to fall out of the race, finding calamity on the final lap of the opening stage.
When Ricky Stenhouse Jr. ran out of fuel, Chastain tried to shoot the gap up the middle in a four-wide situation. At the same time, Kyle Busch was trying to get out from behind the slowing No. 47 machine of Stenhouse. Busch and Chastain made contact, sending the No. 1 Trackhouse Racing Chevrolet spinning. He was unable to continue.
