- Spanish motorcyclist Jorge Lorenzo wins on home soil to extend championship lead
- The 2010 world champion heads home compatriot Dani Pedrosa in Sunday's race
- Last year's winner Casey Stoner loses ground in standings after finishing fourth
- Seven-time world champion Valentino Rossi is back in seventh for Ducati
Jorge Lorenzo extended his MotoGP series lead to 20 points after winning the Catalunya Grand Prix for the second time in his top-level motorcycling career.
The Yamaha rider started Sunday's race from second on the grid, but outshone Honda's polesitter Casey Stoner as the reigning world champion lost more ground in the overall standings after finishing fourth.
It was Lorenzo's third victory in five races this season, and second in a row after winning at Le Mans last month. He was runner-up in his two other MotoGP starts at Montmelo, and also won there with Aprilia in the 250cc class.
He came home five seconds ahead of fellow Spaniard Dani Pedrosa, with Italy's Andrea Dovizioso third on a Monster Yamaha Tech 3.
"I'm really happy with this victory as it was a very tough weekend. We performed a lot better than yesterday as in qualifying it was very hot," said the 2010 world champion, who had to make up ground after Pedrosa took the early lead.
