Australia's Casey Stoner pulled away from championship leader Jorge Lorenzo to win the Catalunya Grand Prix on Sunday, notching up his third win of the season.
The Honda rider hit the front on the first lap and steadily extended his lead, with the only apparent threat to his position coming from the gathering rain clouds which came close to forcing the riders to change to their wet-weather bikes.
Spaniard Lorenzo came in second ahead of Yamaha team mate Ben Spies of the United States. Italian Marco Simoncelli, who had started on pole, was sixth behind compatriots Andrea Dovizioso (4th) and Valentino Rossi (5th).
World champion Lorenzo tops the riders' standings with 98 points from five races, seven ahead of Stoner in second place.
