Stoner also leads Misano warm-up

The Ducati Marlboro rider, who was over half a second quicker than the rest on his way to pole yesterday, set a time of 1:34.644 in today's sunny 25-minute session, despite having run only nine laps.

Almost every other rider did at least 13 laps, yet best-of-the-rest Chris Vermeulen could not bring his Rizla Suzuki within seven tenths of the reigning champion's time.

Fiat Yamaha's championship leader Valentino Rossi was just a whisker behind Vermeulen, while Toni Elias (Alice Ducati), Dani Pedrosa (Repsol Honda) and Colin Edwards (Tech 3 Yamaha) just managed to stay within one second of Stoner's time.

Rizla Suzuki's Loris Capirossi, Fiat Yamaha's Jorge Lorenzo and Honda Gresini's Shinya Nakano complete the top ten.

Alice Ducati's Sylvain Guintoli crashed with five minutes left in the session, while Repsol Honda's Nicky Hayden did not take part at all in this morning's running after injuring his foot during the summer break.

It is as yet unknown whether the former world champion will be able to take part in the race.
