Casey Stoner, Honda, Losail 2011Casey Stoner proved utterly dominant in the opening MotoGP practice session of the season in Qatar.

This weekend's Losail event is spread over four days so that all the sessions can take place in similarly dark evening conditions, which meant an early start to the official running on Thursday night. Honda convert Stoner hit the front just a few minutes in and was never headed, building a 0.61sec advantage over his teammate Dani Pedrosa.

Behind the runaway Australian, the times were much closer, with just 0.23sec covering from Pedrosa in second to third works Honda rider Andrea Dovizioso in eighth.

Hector Barbera was the fastest Ducati, with a shock one-off late fast lap to grab third on the Aspar team's satellite machine. His run pushed Marco Simoncelli's factory-specification Gresini Honda back to fourth.

Valentino Rossi's weekend got off to a better start than he might have expected. The Italian crept up to fifth, 0.7sec off the pace, by the end of the 45 minutes. He was ahead of both bikes from the team he has just left – Ben Spies and Jorge Lorenzo's Yamahas ending up only sixth and seventh.

Pramac Ducati's Randy de Puniet and Tech 3 Yamaha's Colin Edwards completed the top 10 at the end of an uneventful session.
