Frenchman Fabio Quartararo won for the second straight week at Jerez on Sunday as he dominated the Andalucia MotoGP while bikes crashed and broke down behind him in searing heat.

Quartararo, on a satellite Yamaha, was followed home by Spaniard Maverick Vinales and Italian veteran Valentino Rossi, both on Yamaha factory bikes, as only 13 of the 21 starters finished. "That was tough," said Quartararo at the finish.
