Phillip Island may have named a corner in honour of soon-to-retire local hero Casey Stoner, but they might as well have renamed the whole circuit if Friday MotoGP practice was anything to go by.

Turn three is now officially 'Stoner Corner', but the Australian's dominance extends to just about every other turn on the spectacular 4.448km seaside circuit.

Unbeaten at Phillip Island for the past five years, Stoner's recent ankle surgery had cast doubt on his chances of a super sixth.

But after crushing the competition in Friday practice, only physical endurance or the fickle Phillip Island weather look capable of preventing a farewell Stoner victory on Sunday.

The double world champion finished morning practice with a 0.905s advantage over title leader Jorge Lorenzo. Stoner then lapped 0.885s quicker than team-mate Dani Pedrosa in the afternoon session as he dipped into the 1m 29s, under the official race lap record.

Stoner's best time, on lap 11 of 17, was set using the harder rear slick in combination with the softer Bridgestone front.

"It was a very positive first day, we were pretty quick to get on the pace and to be honest I didn't expect to achieve the lap times we did," said Stoner.

"With the extra horsepower we have this year, it's a little easier to get around this place quickly!

"The times we were able to do in the first session were pretty good, but I thought everybody would improve a lot more in the second session.

"But we were able to go quite a lot faster than everybody with almost race distance on our soft tyres and then we put the hard tyre on and were able to improve again.

"This is very positive at this stage of the weekend, but we'll have to wait for tomorrow and Sunday to see where everyone else is.

"My ankle is in a lot worse condition than in Motegi but coming here, there are a lot less right hand corners, it's nice to take a bit of weight off it."

27-year-old Stoner will retire after the Valencia season finale on November 11.
