Jerez de la Frontera: Spaniard Marc Marquez (Honda) flew past the chequered flag way ahead of his rivals in the Spanish Grand Prix at Jerez de la Frontera on Sunday, climbing atop the MotoGp championship standings in the process.
On his way to a second straight victory this season, Marquez beat one of his main rivals for the title, Italy's Andrea Dovizioso (Ducati Desmosedici), who crashed in the 18th lap along with his teammate Jorge Lorenzo and Dani Pedrosa (Repsol Honda), both of Spain, reports Efe.
"I started from the second row but I was clever to overtake the other riders in the beginning", the Spanish rider said, adding, "It was almost impossible to overtake Lorenzo". All three riders went sliding into the gravel and were driven out of the race.
