The Joe Gibbs Racing drivers started on the first row and led for a combined 186 laps at the 200-lap Xfinity Series Furious 7 300, but at the end of the night it was Busch that bested his teammate for the win.

“I didn’t know if I was going to be able to beat Matt tonight," Busch told NBCSN after the race. “I can’t say enough about (crew chief) Chris Gale — all the adjustments he made all night long to make the car better and better.”

Kenseth used a late effort to get around Busch with just two laps to go, but as the No. 20 car pulled up beside Busch, Kenseth’s progress was blocked by the lapped-car of John Wes Townley. 

“I couldn’t get that chicken man out of the way,” Kenseth said. “I thought we had a good car but Kyle had a better car than we did.”

The victory was Busch’s 74th career Xfinity Series win. 

Bush, however, could be facing penalties after his car was deemed too low in all four corners in a postrace inspection. According to ESPN, any penalties will be announced on Tuesday.

Bubba Wallace Jr. had a career-best third-place finish. He was followed by Paul Menard and Ty Dillon. 

“This is a great night for us,” Wallace said after the race. “It is really a win for us. If I look at it, Matt (Kenseth) and Kyle (Busch) really didn’t count so we actually won tonight.”

With his fifth-place finish, Dillon jumped Chase Elliott for second in the Xfinity Series points standings. Dillon now trails leader Chris Buescher by 25 points entering next Saturday night’s race at Kentucky Speedway.
