Chastain, in just his second race with Chip Ganassi Racing, led 180 of 200 laps and swept every stage. He had to survive three restarts in the last 20 laps to secure the win, which came in his 132nd series start at the age of 25.
It is Chastain’s first overall NASCAR win in 215 starts across all three national series.
“Thank you all so much,” Chastain told his team over the radio. “I can’t thank you all ever in my whole life enough.”
“Holy cow. I’m just a watermelon farmer from Florida,” Chastain told NBCSN on the start-finish line. “I’m not supposed to do that. Wow. … Man, that is a testament that anything in life is possible.”
In Victory Lane, Chastain kissed a watermelon in celebration.
Chastain usually competes for JD Motorsports. He made his CGR debut in the No. 42 two races ago at Darlington. In that race he started from the pole and led 90 laps before his chances at winning ended with a final stage incident with Kevin Harvick while battling for the lead.
Chastain has one more race scheduled with CGR next week at Richmond Raceway.
With his second-place finish, Allgaier secured the regular-season title and 15 bonus playoff points.
