Cal Crutchlow took his second victory of the season with a dominant victory at Phillip Island. Valentino Rossi and Maverick Vinales completed the podium, whilst recently crowned champion Marc Marquez crashed out of first place on lap 10.
The Brit had started second on the grid, but found himself being swallowed up off the line. He worked his way forward through the pack to trail Marquez before the Spaniard slid out at Honda corner. Crutchlow extended his lead over Valentino Rossi to over four seconds to take his first premier class victory in the dry.
Rossi coasted to a second place having started down in 15th, keeping well clear of the scrap behind him. Maverick Vinales tussled with his team mate and Andrea Dovizioso for third, a scrap that saw Aleix Espargaro crash out. Pol Espargaro faded after a strong start, and Jorge Lorenzo rounded off the top six.
It was a good day all round for the British riders, as Scott Redding and Bradley Smith, on his second race back from injury, finished seventh and eighth. Home rider Jack Miller finished tenth, having tussled with Nicky Hayden, who was standing in for the injured Dani Pedrosa.
Thomas Luthi took the victory in Moto2, taking him to second place in the championship, 22 points behind Johann Zarco with two rounds to go. Sam Lowes crashed out early on and Danny Kent also failed to finish. Brad Binder continued his domination of the Moto3 class with his sixth win of the season. The race had been red-flagged due to a huge multi-rider accident involving John McPhee.
