While new Ducati Xerox team-mate Noriyuki Haga collected two second place finishes at Qatar on Saturday, Michel Fabrizio was left with two DNFs next to his name.
The Italian suffered a technical problem in race one, prompting him to deactivate his 1198's traction control - causing him to fall.
Race two was an equally miserable experience, with a bad start followed by severe rear tyre problems. Fabrizio pitted for a new rear tyre and set his fastest lap of the race on his return to the track, but by was so far behind that he decided to retire.
“Today is a day to forget; we must move on,” said Michel. “In race one I had a technical problem with the anti-spin so I deactivated it but riding without that electronic support was hard and caused me to fall.
“In the second race I decided to come into the box after eight laps to change the rear tyre that had caused me problems from the first lap,” he confirmed. “The tyre was changed and I went back out but the gap that had opened up prevented me from fighting for points and so I concluded my race early.”
Fabrizio has now slipped to eleventh in the championship with 24 points, compared with 85 for title leader Haga.
