Marc Marquez: MotoGP leader gains fourth win of season at Aragon Grand Prix
MotoGP championship leader Marc Marquez moved 52 points clear in the title race with victory at the Aragon Grand Prix.
The Spaniard, 23, started on pole but slipped to fifth place after an early technical issue.
He recovered and overtook Valentino Rossi with 12 laps to go, securing his fourth win of the season and taking his championship total to 248 points.
Rossi struggled to close down Marquez's lead and fell behind defending champion Jorge Lorenzo to finish in third.
