Marc Marquez earned his second win of the season with victory at the German MotoGP at Sachsenring on Sunday, moving to the top of the championship standings as he took full advantage of the absences of title rivals Dani Pedrosa and Jorge Lorenzo.
The Spaniard, 20, hit the front early and built up his lead to claim victory with Britain's Cal Crutchlow second and six-time world MotoGP champion Valentino Rossi in third.
Marquez's winning time was 41 minutes, 14.653 seconds over the 30 laps, to beat Crutchlow by 1.55 seconds. Rossi was another nine seconds back.
With Pedrosa and Lorenzo missing the race because of injuries, pole sitter Marquez lost ground at the start to find himself in fourth by the first bend.
But he hit back, taking the lead from Stefan Bradl along the main straight on the third lap.
Marquez, in his first MotoGP campaign, was following up his Grand Prix of the Americas victory in Texas in April.
He has now finished on the podium in all seven races he has finished in 2013.
The victory allowed Marquez to overtake compatriot and Honda teammate Pedrosa, who was forced out after fracturing his collarbone in Saturday's practice, atop the standings with 138 points, two clear of Pedrosa.
Reigning world champion Lorenzo on Friday re-injured the same left collarbone he broke two weeks ago.
He underwent surgery on Saturday in Barcelona.
"I'm happy, it's great to win, but you shouldn't forget that both Pedrosa and Lorenzo weren't here," Marquez said. "I hadn't expected to control the race like that."
Both Yahama Tech 3's Crutchlow and Rossi on the Yahama factory bike complained about losing grip on their rear tyres, but the British rider produced a brave performance after twice crashing in Friday's practice session.
"I was trying to catch [Marquez]," said Crutchlow, who raced with an injured hand. "I had a good start, even though it might not have looked like it. I struggled a bit with the rear tyre.
"I am pleased with the finish position we had here, having come off the floor twice on Friday. It's not been a great weekend and I admit I don't feel great."
