Miguel Oliveira described his victory in Indonesia as an emotional rollercoaster as the Red Bull KTM rider triumphed in tricky conditions.
Oliveira finished more than two seconds clear of world champion Fabio Quartararo in a curtailed race at the Mandalika International Street Circuit, which started over an hour late due to torrential rain.
Quartararo qualified in pole position but was passed by Oliveira and Jack Miller, who held the early lead before the Portuguese made the most of superior pace.
The 27-year-old then navigated the wet track superbly to claim a fourth race win in MotoGP™ and back up his claims in the build-up that he can compete for the title.
"Emotionally, it was a rollercoaster," he said in parc ferme. "The start was perfect and in wet conditions, it is so difficult to find the limit.
"I followed Jack and knew I could be faster. I opened [a gap] and then it was a matter of managing it to the end.
"It hasn't been easy, the last few months haven't been easy for me. I promised my daughter I'd get a trophy in Indonesia – this one's for you.
"Let's go to Argentina, let's see what we can do, but now I'm really happy to be here."
Quartararo dropped to fifth before a supreme ride in the second half of the race saw him end a run of four consecutive non-podium finishes.
The Monster Energy Yamaha star felt the points could prove valuable come the business end of the season.
"I didn't expect it," he said. "Honestly, since the warm-up, I felt that we had something more than usual because we know that with wet conditions we always have more difficulties.
"When it's completely wet and with traction, I know my potential, but today I was better than I expected. I saw an opportunity and took it.
"These are super important points. It was my first podium with a full wet floor."
