Quartararo dominates the Andalucia MotoGP to take back-to-back victories at Jerez.

Bagnaia was on course for a safe second place and first MotoGP podium until a late engine failure on his Pramac Ducati.

That instead went to Vinales, who finally passed team-mate Rossi on the penultimate lap. Rossi then held off a closing Nakagami to claim his first podium since Austin last season.

Morbidelli was also in the podium hunt until his M1 ground to a halt on the main straight, just as happened to Rossi's bike one week ago.

The extreme heat saw a spate of accidents and only 13 finishers, starting with Binder clipping Oliveira into a highside at turn one.

Reigning MotoGP champion Marc Marquez attempted a return to action on Saturday, just four days after surgery to plate a fractured right arm, but withdrew after qualifying.

Crutchlow (wrist fracture) and Rins (dislocated shoulder) made their injury comebacks on Friday and were starting their first race of the season today.

There will now be one weekend off before the Czech Republic round at Brno, where Marquez will try to return.
