Nicky Hayden's impressive third position at last week's Sepang test also provided inspiration for satellite rider Aleix Espargaro.
Since the 800cc era began in 2007, few Ducati riders have been able to get near 20-time MotoGP race winner Casey Stoner - but Hayden finished directly behind his factory team-mate with the new 'big bang' Desmosedici GP10.
However, the three satellite riders didn't do so well - rookie Hector Barbera was 13th for Aspar, followed by Pramac team-mates Mika Kallio and Espargaro in 14th and 15th respectively.
"I remain very confident because I'm sure we have every possibility to do well,” insisted Espargaro, starting his first full MotoGP season in 2010. “I am very pleased to see the two official Ducatis in the top three: I am sure we will find soon the right solution to fight for the best positions as well.”
Team-mate Kallio wasn't sure why he was so far down the order.
"Things have not gone as we expected. I feel very good on the new bike but perhaps I have yet to find total confidence to push to the maximum,” commented Kallio. “We cannot make any more mistakes in the next test in Qatar next month."
Yamaha's world champion Valentino Rossi was fastest of all.
The Qatar test takes place on March 18-19.
