Hill took the lead during a round of pit stops under caution late in the race but a spin by Parker Kligerman with four of 147 laps remaining sent the race into a two-lap overtime.
Hill appeared to spin his tires on the restart – a problem that plagued him much of the race – and Hamlin quickly got around him to reclaim the lead.
Hamlin edged Hill by 0.657 seconds to earn the victory in his only series start of the 2023 season. It’s the first series win for Hamlin since 2017 and the 18th of his career.
“I appreciate everyone at Joe Gibbs Racing giving me the opportunity to do one Xfinity race per year and it’s great to have a win,” Hamlin said.
“It took a while (to find a rhythm). I really needed some long runs, but I really didn’t want to show everything we had until the very end of the race there. It was going to be cool to see that race play out (under green) but, still, a great win.”
John Hunter Nemechek, who won both stages, finished third, Cole Custer was fourth and Josh Berry rounded out the top five.
Completing the top-10 were Riley Herbst, Justin Allgaier, Sheldon Creed, Kyle Busch and Daniel Hemric.
With one race remaining in the regular season, Herbst holds a one-point advantage over Kligerman for the final playoff spot.
