With a fast and focused performance Australia's only MotoGP rider, Jack Miller finished a superb sixth in a rain soaked race at Misano on Sunday.

It was another masterclass in wet track riding by Miller, who surged into his second top six result of the season from 14th on the grid.

Miller's previous sixth place was at the Dutch TT in June.

Miller had threatened a big haul of points after qualifying and the Australian delivered on cue, despite the slippery and tricky conditions at the Misano World Circuit Marco Simoncelli.

Miller dashed into ninth place on lap one and two laps later was locked in a titanic battle with Cal Crutchlow and Maverick Vinales for fifth place.

On lap six Miller had moved to fifth and settled into a long contest with Vinales before fading rear grip left him unable to hold off the late race challenge from Michele Pirro.

“At the start of the race I felt I had more pace than Vinales and Crutchlow but by the end of the race my pace dropped and I probably switched the engine map too late to help look after the rear tyre,” he explained. “It was good on the edge but I had lost some drive grip and it wasn't possible to hold off Pirro in the final laps. This was my best weekend in the second half of the season so far and with some good points I am looking forward to the next race in Aragon.”

Miller's sixth place is a confidence boost in advance of the next race, the Aragon GP, in two weeks.
