( CNN ) -- 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 . Stoner sets pace in Catalunya qualifying . `` 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 . `` The grip on the track after the rain this morning was also not so great . I followed Dani and watched him , he slowed his pace and eventually made a mistake so I was able to pass him then give it full throttle . '' Pedrosa was disappointed despite finishing on the podium at Montmelo for the eighth time , being 10 points behind teammate Stoner in third overall . `` A second place is always a second , but I really wanted to win today , I can not feel happy , '' he said . `` I tried to attack but with 10 laps remaining I could n't keep the pace . It was hard to control the bike on braking and in the exit of the corners , so I was defensive because I knew my corner speed was not so good . I made a mistake and I had a big wheelie , so Jorge got past me and I could n't follow him . '' Stoner , who plans to retire at the end of this season , was also disappointed -- having won the previous four races held at Spanish circuits . `` We gave it everything at the end but we just did n't have the pace , especially in the beginning with the hard tire , '' the Australian said . `` With the performance we had during the weekend we expected to be a little stronger throughout the race . '' Dovizioso 's British teammate Cal Crutchlow was fifth ahead of Spain 's Alvaro Bautista and seven-time world champion Valentino Rossi of Ducati . Germany 's Stefan Bradl was eighth on a Honda , with Ducati 's Nicky Hayden ninth and fellow American Ben Spies 10th . Spies dropped from second early in the race , which was a big blow after qualifying in fourth on Saturday . `` I just made one mistake in the race and blew our chance , '' the 27-year-old said . `` We were going good in the beginning but I was getting impatient with Dani . `` He was holding me up but I could n't make the pass on the straight so I had to go for it on the brakes and unfortunately got out onto the edge of the track . I got up and we got back into it and our pace was pretty good , unfortunately it was too late to get back to the front . ''
