Marquez completes US sweep
Repsol Honda's Marc Marquez cemented his place at the top of the MotoGP standings with his third straight win in Indianapolis on Sunday.
Marquez comfortably beat team-mate Dani Pedrosa, their third one-two of the season, with Yamaha's Jorge Lorenzo making it an all-Spanish podium.
Having won at Laguna Seca last week and in the early-season event in Texas, it completed a clean sweep of this season's American races for 20-year-old Marquez.
Pedrosa slipped ahead of Lorenzo early on the penultimate lap and held on to second, over two seconds ahead of Lorenzo but almost three and a half behind Marquez.
Lorenzo's team-mate Valentino Rossi was fourth with Cal Crutchlow fifth for Monster Yamaha, the Italian overtaking both Crutchlow and Alvaro Bautista on the last lap.
The top five racers on the day occupy the same positions in the season standings, separated by 61 points with Marquez 21 clear.
British rookie Bradley Smith (Monster Yamaha) also made a late move, overtaking Ducati duo Nicky Hayden and Andrea Dovizioso at the last corner to snatch eighth place.
Earlier in the day, MotoGP organiser Dorna confirmed the series would return to Indianapolis next season for the final year of the track's existing contract and also that the two parties "have started discussions about a long-term relationship past the terms of the current contract".
Doug Boles, president of Indianapolis Motor Speedway, responded: "We are also eager to continue working with our friends at Dorna to ensure an exciting long-term future for MotoGP at the 'Racing Capital of the World'.
"I'm extremely pleased that MotoGP will be returning to iconic Indianapolis track in 2014 to bring the pinnacle of motorcycle racing to the American fans.
"The Brickyard not only attracts a great crowd every year, but its heritage and history in the world of motor racing also helps grow the popularity of MotoGP in the United States and around the world."
