Valentino Rossi is confident of a competitive showing in this weekend's Portuguese Grand Prix, even if conditions remain wet.
MotoGP hasn't had a wet race so far this year, but the rain at Estoril was so bad on Friday that only four riders left the pits for the first or the two practice sessions.
Things improved for the afternoon, when all 17-riders lapped for the full 45-minutes on wet tyres.
Rossi was third fastest after his 20 laps, the best of which was just 0.361sec behind Fiat Yamaha team-mate Jorge Lorenzo, winner at Estoril for the past two seasons.
"This afternoon was a normal wet practice and I'm happy about my performance," said the Italian. "I am close to the top, was fast from the beginning of session and had a good feeling with bike.
"Unfortunately we were losing a little bit in some sections of the track, especially the last one because the bike was moving a little too much.
"We will try for tomorrow to improve the settings, it's important that we made a good start this afternoon as this morning's session was cancelled and it looks like the weather may not be very good over the weekend, so we will not have a lot of time to set up the bike!"
"It was a good session today, we started with a good base and Valentino was fast throughout the practice," confirmed team manager Davide Brivio. "There are still some improvements to make both with the electronics and the balance of the bike. We got some really useful information from the session so if we have any further wet sessions or a wet race on Sunday we can continue with this good base."
Ducati's Nicky Hayden split the Yamahas with the second fastest lap time.
Saturday's two sessions will be one hour long to make up for the washed out Friday morning session.
