In a wet opening Moto2 practice session Frenchman Johann Zarco led the way ahead of the Spanish Grand Prix.
Zatco, in his rookie campaign in the intermediate class, ended the session with an almost one second advantage over Andrea Iannone and Xavier Simeon with wet weather renowned specialist Anthony West fourth fastest but over seconds adrift.
As ever in such treacherous conditions it is impossible to gauge much from the results sheet but with Ratthapark Wilairot and Randy Krummenacher both crashing it was clear just how treacherous the downpour had made theJerezcircuit.
Unlike in the MotoGP practice session however the conditions were at least stable and it meant that entire field made their way onto the track with West initially setting the pace.
With rain expected to remain for the duration of the weekend it is clear that the riders will have to get used to the conditions and the afternoon sessions should feature more excitement.
Scott Redding was fifth fastest ahead of Bradley Smith with Pol Espargaro the only other rider to finish within three seconds of the fastest time.
Julian Simon made a change to the Suter chassis for this weekend and while the Spaniard ended the session a respectable eighth fastest he surely would have preferred a dry session where he was able to gather more meaningful data. Thomas Luthi and Alex de Angelis rounded out the top ten.
For Luthi this race is of crucial importance the Swiss rider dominated practice and qualifying inQatarbefore tussling with Marc Marquez on the final lap and falling down the field to an eventual fifth place finish. The former 125cc world champion will know that it is crucial to regain the initiative in the early season title battle as to give Marquez a significant headstart after only two rounds could be catastrophic to his championship challenge.
Marquez ended the session 14th fastest.
