During a Lap 35 final stage at San Diego, Sam Mayer clipped the inside wall, shooting him across the nose of Anthony Alfredo and directly into the concrete wall lining the outside of Turn 1.
At least 23 cars were involved in the violent crash according to The CW, and NASCAR immediately red-flagged the event. It was the second red flag of the race, with the first one caused by a metal cover that came up and damaged a car.
