Spain's Jorge Lorenzo, riding a Yamaha, moved to within 18 points of Moto GP championship leader Valentino Rossi after winning the Portuguese Grand Prix yesterday. Australian Casey Stoner and another Spaniard, Dani Pedrosa, finished second and third respectively.

Lorenzo's fourth win of the season, means he has closed the gap to Rossi, his teammate at Yamaha, with just three races left.

Lorenzo overcame the early surges of Pedrosa to take control of the race on the first lap and went on to lead almost from start to finish with Rossi finishing fourth.

On his title chances, Lorenzo said: "It will still be very difficult but now we can say that it is not impossible. I think I can take a few risks because I don't have anything to lose."
