Portuguese rider Miguel Oliveira held off a late challenge from Frenchman Johann Zarco to win the Catalonia MotoGP on Sunday. Australian Jack Miller took third after championship leader Fabio Quartararo was hit with a three-second penalty. "Everything was so hard: tyre management, keeping cool when Fabio was putting the pressure on me for so many laps," said Oliveira, who delivered a series of metronomic laps on his KTM. 

"I was not superfast but I was constant and it paid off." Both Quartararo and Miller led briefly, but had problems. Miller said he "felt mega" but had trouble with tyres overheating. "Miguel and Fabio were able to be very consistent, whereas I made a few too many little mistakes," said the Australian. Frenchman Quartararo was penalised for going way off the track on his Yamaha at the chicane four laps from the end. The rider from Nice finished the race barechested and without a piece of required safety gear, after unzipping his jacket and discarding his chest protector.
