Rossi - who signed a two-year deal to remain in MotoGP with Yamaha on Thursday - ended the day ninth, which he blamed on mistakes during his time attack.
Italian MotoGP rider Valentino Rossi has signed a two-year contract extention with Movistar Yamaha. The soft and medium are in play and I don't know what to expect in the last 5 laps of the race.
Yamaha's other rider is Spaniard Maverick Vinales, who finished third overall last season with Rossi fifth. As of the start of this season, Rossi has 227 podiums, 64 poles and nine championships in a GP career that stretches all the way back to his start on 125 cc two-strokes in 1996.
"Having the opportunity to work with my team, with Silvano, Matteo and all my mechanics, and working with all Japanese engineers, Tsuji-san, and above all Tsuya-san, is a pleasure - I'm happy".
Moreover, Rossi is the only rider to win premier class titles on five different types of motorcycles (500cc 4-cylinder two-stroke, 990cc 5-cylinder four-stroke, Yamaha 990cc 4-cylinder four-stroke, Yamaha 800cc 4-cylinder four-stroke and a Yamaha 1000cc 4-cylinder four-stroke). "It might be risky, but if I followed that line of reasoning I would have stopped many years ago", Rossi said.
Yamaha Racing mananing director, Lin Jarvis says the decision came natural from both sides.
"The news may not be a great surprise because Valentino has made it clear that he wanted to continue to race, but the reconfirmation will surely come as welcome news for his millions of fans around the world", Jarvis said.
The mercurial Italian is not alone in having won Grand Prix World Championships; the grid for this year boasts a total of 32 titles across all classes, spread across 12 competitors. All of us more of less start in the best way possible. MotoGP riders hit 350km/h before the second hardest braking manoeuvre of the entire championship, requiring eight kilograms of lever pressure for 5.1 seconds, over a distance of 290 metres.
Five of the last six races here have gone the way of the factory Yamaha team and although the winter hasn't exactly gone to plan for them, they will probably start the weekend as slight favourites.
The Tech 3 Yamaha rider's future has become one of the hottest talking points in the silly season, with almost every manufacturer reported to be monitoring his situation.
If the 27-year-old Frenchman can continue to develop in his second season we could have a shock on our hands.
The circuit is 5380 metres long, with 16 corners and a main straight of more than a kilometre - one of the longest on the Grand Prix calendar.
