In a race whose aftermath left hometown driver Kyle Busch with a bloody forehead, Martin Truex Jr. passed the faltering car of Brad Keselowski on the white-flag lap and cruised to a sweep of all three stages in Sunday’s Kobalt 400 at Las Vegas Motor Speedway.
As Truex approached the checkered flag to win a Monster Energy NASCAR Cup Series race for the first time this season and the first time at Las Vegas, Joey Logano’s Ford slid up into Kyle Busch’s Toyota in a battle for third position. Busch spun into the inside wall on pit road and limped across the finish line in 22nd place.
Logano salvaged fourth behind Truex, runner-up Kyle Larson and Chase Elliott, but the battle wasn’t over when Truex took the checkers. Busch hustled up pit road to confront Logano and threw a punch at Logano’s head.
Logano’s crew stepped into the fray, and took Busch to the pavement. In the melee, Busch sustained a bloody bruise to his forehead.
