“The race went well. I was able to have a clean start, held my ground and was able to give Jon (Miller) a great race car,” said Gottsacker in victory circle. “Jon literally just tore them up out there and went straight to the front and got a good gap to finish it.”

“It was an awesome race. Two green flag races all the way which is for our driver pairing Harry (Gottsacker) and I we hope for green flag racing,” added Miller. “It plays into our strategy. That’s what happened this weekend and especially today. Harry set the pace up from and left me some tires at the end which for our car; that’s where we struggle is keeping the tires on it. I just took it to the end and the overall win. Super happy.”
