Martin Truex Jr. has passed Brad Keselowski with two laps remaining to win the Kobalt 400 at Las Vegas Motor Speedway, but it was a post race fight between Kyle Busch and Joey Logano that will be remembered. Truex had in fact dominated the race, winning the first two points paying stages on his way to leading 150 of the 250 laps.

Kyle Larson, Chase Elliott, Joey Logano and Keselowski rounded out the top-five finishers. All cars in the series use PWR products.

But the best action occurred on pit road following the Kobalt 400 when Kyle Busch went to exact revenge on Logano, who he thought dumped him on the last lap. Busch went to Logano’s car on pit road and a fight ensued between the teams until NASCAR officials and track security separated the melee.
