Andrea Dovizioso didn't make the start to the Aragon MotoGP that he hoped as the factory Ducati rider finished eighth fastest on the GP15.
Dovizioso, though, is taking heart from his lap time of 1m 48.575s, which leaves him within four tenths of Valentino Rossi in second place after Jorge Lorenzo blazed a trail to finish almost seven tenths clear at the top on the Movistar Yamaha.
The Italian rider, who finished ahead of team-mate Andrea Iannone by 0.051 seconds, said: “It wasn't a very good day for us, even though there's not much of a gap to second place. This afternoon we encountered some difficulty and we couldn't do as many laps as we would have liked.
“We are working on the electronics and in particular on the mapping, but we have not yet been able to find an entirely satisfactory solution and this didn't allow us to do the usual job of fine-tuning the set-up,” he added.
“In any case, we are positive and so now will work to try and be more competitive tomorrow.”
