Oliveira crossed the line 0.730s ahead of Ducati duo Jack Miller and Bagnaia at the Chang International Circuit, in a race significantly delayed by rain.

“It was a long race, but I can’t complain. When it started, I had a flashback of Indonesia,” said Oliveira, who also showcased his wet weather skills this season in his victory at the Indonesia MotoGP.

Bagnaia was made to work for his third-placed finish by Pramac Ducati’s Johann Zarco, but held on to reduce Frenchman Quartararo’s lead in the standings from 18 points to two.

“I’m very happy, it’s like a win for me,” Bagnaia said.

“I want to thank Jack (Miller), he gave me a motivational chat before the race.”

Quartararo had a disastrous start to the race, dropping down from fourth on the grid to 17th place on the first lap before ending up outside the points.
