Spaniard Marc Marquez edged closer to the world title with a win at the Aragon MotoGP ahead of Jorge Lorenzo on Sunday, when another of his closest challengers Dani Pedrosa crashed out in spectacular fashion.
The 20-year-old rookie started on pole but needed to reel in world champion Lorenzo, who had made a flying start to hit the front, and he eventually passed the Yamaha rider with ten laps to go and cruised home.
Marquez's Honda team-mate Pedrosa was in second place when he high-sided his bike and crashed as he came out of a corner with 18 laps to go, but initial reports said he had not suffered a serious injury.
Italian Valentino Rossi came in third ahead of Spaniard Alvaro Bautista, Germany's Stefan Bradl and Britain's Cal Crutchlow after a thrilling final-lap tussle between the four.
Championship leader Marquez moved on to 278 points with four races left, 39 ahead of second-placed Lorenzo. Pedrosa is third with 219 points.
