It is Haley’s second win of the year after he won at Talladega.
The night was dominated by Kaulig Racing, with Haley winning Stage 1 and Allmendinger claiming Stage 2. The team led 68 of 100 laps.
“An amazing effort by Kaulig Racing,” Haley told NBCSN. “Obviously, I hate that AJ and Ross got together there. … Parked it right here on the double yellow line where I went down too low about two years (and was disqualified from a win) in a Xfinity race. A little humor there.”
Chastain wound up finishing sixth.
“It’s terrible to run into your teammate like that,” Chastain told NBCSN. “Must be my fault, though. It’s unfortunate, we did everything right all night. We just got to win. … Did everything right to be the the best teammate I could. I haven’t always been. Last lap, I don’t back down and I’m going to go for it. … I hate it, man! It’s not going to help me moving forward.”
Allmendinger finished 15th after leading a race-high 58 laps. He said Chastain’s move was fair.
“I try to take care of my teammates, but it is what it is, it’s for the win,” Allmendginer told NBCSN. “Ross is going for the championship and going for a win there. I saw him get low and I thought maybe he’d take care of me a little bit considering I was there. But he’s going for the win.”
