Tyler Reddick held the lead as a late caution sent Sunday’s race into a two-lap overtime and Chastain used a deft move in the essess to reclaim the lead.
Chastain took the white flag – signaling the last lap – as the leader but AJ Allmendinger and Alex Bowman did not let him get away.
Coming into the final turns, Allmendinger got around Chastain for the lead, then Bowman went to the outside of Allmendinger and Chastain to briefly grab the lead.
Coming to the final turn, Chastain swerved into Allmendinger, who hit Bowman, sending both cars off course and Chastain escaped with his first career Cup Series victory in 121 starts.
The win is the first for Trackhouse Racing, which is in just its second fulltime year of Cup series competition. The team is co-owned by Grammy Award-winning rapper Pitbull and former driver Justin Marks.
After coming to a stop on the frontstretch, Chastain exited his No. 1 Chevrolet was presented a watermelon, which smashed on the track. Chastain grew up as a watermelon farmer in Florida.
“It’s insane,” Chastain said. “To go up against some of the best with AJ, I mean, I know he is going to be upset with me, but we raced hard, both of us, and he owes me one.
“But when it comes to a Cup win, man, I can’t let that go down without a fight. … People don’t know how good this group is. I can’t believe Justin Marks hired me to drive this car.”
Asked how he managed to win after losing control of the race on the final restart, Chastain said, “I don’t know how we got back by. I was so worried about AJ on the second-to-last restart that I let Tyler drive right by both of us.
“And AJ is so good. I’ve learned so much from him. And it was like how do you go beat the guy? He taught me so much. I’ve learned so much from so many people from 417 Speedway back home with my dad.
“I was thinking about on those late restarts, my dad used to make me race on old tires, and back then I was not going to win. It was in my head before I even started. It crossed my mind, like, ‘We’re not going to win, we’re on old tires’, but I couldn’t think that way.
“We did it!”
