Tyre problems caused many of the cautions at Fontana California in the NASCAR Sprint series race but Kurt Busch driving the unbreakable PWR cooled Toyota Camry for Joe Gibbs Racing was able to avoid the numerous wrecks as well as looking after his tyres to win the race.
It was the first race win of the season for Busch and virtually guarantees his entry in the Chase under the new championship rules.
Busch held off rookie driver Kyle Larson on the final green-white-chequered restart to take the win.
