Australian Moto2 prodigy Remy Gardner claimed his maiden Grand Prix victory, taking out the Portuguese title at Algarve.

Gardner, son of legend rider Wayne, took out the honours in the final race of the season ahead of Luca Marini and Sam Lowes.

Italian rider Enea Bastianini claimed the 2020 Moto2 Championship after finishing fifth in the race, winning the crown narrowly ahead of Marini and Lowes.

Gardner finished sixth in the championship tally and was speechless following his first Grand Prix victory.

"No words. Thanks to everyone who has stood by me and for all the support. To win my first GP is amazing," Gardner wrote on Twitter.

The 22-year-old was in disbelief following the race.

"I honestly have no words," he said post race, describing himself as "so f---ing happy".

"My first win, a bit emotional you know on the cool down lap. We have been strong here all weekend and I thought I could win and I came in thinking with that mentality lets try and win it, its our last race and I've got nothing to lose and we did it.

"We worked so hard as a team. All the weak points we straightened out over the weekend and even in the race I was still adapting to my style and learning from Luca.

"In those last couple of laps I saw that I had the pace and I stayed behind Luca and on the last two laps I passed him, I pulled the pin and pulled out a gap and I am just lost for words honestly."

Fellow Australian Jack Miller finished second in Algarve leg of the MotoGP and finished 7th in the championship standings.
