Andrea Dovizioso said it was 'unacceptable' to lose 20 world championship points after he was wiped out by his Ducati team-mate Andrea Iannone on the final lap of the Argentina MotoGP.
Iannone attempted an unlikely pass on the inside at the final turn but lost the front of his GP15, denying Ducati a double podium as Valentino Rossi and Dani Pedrosa capitalised to fill the rostrum places behind Marc Marquez.
Race Direction imposed a three-place grid penalty on Iannone for this weekend's Austin round plus a penalty point as a result of the incident.
Robbed of a runner-up finish, a disappointed Dovizioso said: “I'm really disappointed because to lose at that point is a disaster. To lose 20 points and be second in the championship to [Marc] Marquez by just one point is just very unfortunate.
“I approached the race and the weekend to take the best result for the championship and this I think is the way to approach everything when you are in a factory team and you want to get good results.
“We worked really hard in the last two years and we really created a good bike together and to lose the points like this is unacceptable,” he added.
“I didn't know if Iannone was there or Valentino [on last lap] but when I crash I knew it was Iannone and I can expect something like this.”
In spite of the setback, Dovizioso was clinging to the positives from the weekend as he looks to bounce back at the Circuit of the Americas in Austin at round three this weekend.
“This weekend was very difficult for everybody and we were able to manage the situation, we were very competitive in the qualifying and in the practice and I was able to finish second in the race,” he said.
“I was able to pass Valentino and for the championship race this is important, so these are the positive things for the next race.
“Austin is a really nice track and we have to confirm again in a different situation our speed.”
