Maverick Vinales saw a career best second on the grid count for nothing when an electronic problem saw him plummet to eleventh on lap one of the Italian MotoGP.
The Suzuki star, now confirmed as moving to Movistar Yamaha next season, had matched his previous best grid place by qualifying behind only future team-mate Valentino Rossi, then set the pace in morning warm-up.
But his hopes of a second podium in succession were ruined before he reached the first turn.
“We got a problem on the electronics,” Vinales explained. “The bike stopped pushing, giving power, then everybody overtake me. I changed gear and it came back to normal.”
The Spaniard fought his way to sixth place by lap 10, but didn't advance any further.
“I stressed a lot the tyres in the first laps, trying to overtake, trying to accelerate, I destroyed the tyres more than if I was in a leading position. I'm really sad, because I think after warm-up, it was possible to fight for the podium.
“The bike was working good with the set up. Finally when it was four laps to go, I really didn't push, because I was really on the limit, close to crashing many times. So I said 'OK, today, sixth position, this is my place'.
“But the bike was working good. I recovered a lot to catch Dani and after I passed all the riders, I made the same pace as Jorge and Marc. So sure with a good start I can be there. But one more time I don't have the chance to do it.”
Team-mate Aleix Espargaro finished ninth.
