The race was sent into a two-lap overtime following a horrific crash involving Ryan Preece that resulted in the Stewart-Haas driver being sent to hospital, with Kevin Harvick in the lead on his final outing at the superspeedway.
But Harvick had Buescher and RFK team-mate Brad Keselowski behind him, and a push from the 2012 Cup champion moved Buescher ahead of Harvick shortly after the restart. He then held off Keselowski by 0.098 seconds at the checkered flag to claim his third win in the past five races.
It’s the first 1-2 finish for RFK Racing since the 2014 season and Buescher will enter the 2023 playoff field as the fourth seed.
The 30-year-old said the result was “as much Brad’s win as ours right there”.
“That was the right help, aggressive, sticking with us,” he said.
”I was waiting for him to do something there coming to the finish. I figured we’d be side by side. Looked like it stalled out a little behind there.
“Just so thankful for Brad for all those pushes at the right time. Found each other here and there throughout the race, lost each other, and got back on when it counted.”
Aric Almirola ended up third ahead of Chase Elliott, for whom fourth place was not enough to continue his unbroken streak of playoff appearances.
Joey Logano rounded out the top five ahead of Alex Bowman and Kyle Busch, as Harvick dropped to ninth behind William Byron. Corey LaJoie completed the top 10.
