"We worked very well with Bridgestone and together with their technicians we made a late tyre change and it was the right choice because my tyre worked very well until the end, as my times showed! It's the first win for us with Bridgestone so this is a great moment also for this reason and I want to say thank you to them.
"We were fast from Friday morning here and step by step we've found the perfect set-up and today the hard work paid off for everyone. We've had four races and four different winners so this shows how close the championship is, now we need to keep going because our rivals are all very near.
"Lorenzo did a great race today with his injuries, so this is a good day for everyone in the team. Thank you to my team and everyone at Yamaha, it's great to be here again," he concluded.
In the championship standings, Rossi is now just two points behind rookie team-mate
Jorge Lorenzo - who rode injured to fourth in Sunday's race - with Pedrosa a further seven points ahead. Fellow 2008 race winner Stoner remains fourth, but is now 25 points from the top.
"We needed this!" admitted team manager Davide Brivio. "It's a fantastic feeling for everyone to win again and Valentino did a perfect job today. There are many good things about this particular win; it's the first with
Bridgestone, the first for a long time and also it's put us right back in touch for the championship after a poor start in Qatar. It's important that we continue like this but everyone has a great motivation and confidence is running high in our garage."
