THAILAND - Honda's Marc Marquez sealed his sixth MotoGP title, and eighth world championship overall, after winning a thrilling Thai Grand Prix on Sunday.
The Spaniard pipped pole sitter Fabio Quartararo at the final corner before the line after a long on-track battle, while Monster Yamaha's Maverick Vinales finished in third.
Marquez, 26, was taken to hospital on Friday after being catapulted off his bike in a huge practice crash.
Later, he returned to the track after being given the all-clear, but crashed out again in Saturday's qualifying session where he placed third.
With four races to go in the season, Marquez, had to score two points more than Italian Ducati rival Andrea Dovizioso, who finished fourth at Buriram's Chang International Circuit, to wrap up his fourth championship in a row.
After celebrating, Marquez said: "I was planning the weekend to try to win the race, it doesn't matter about the championship or the distance between me and Dovi.
"The target was try to find the best way to win the race and it's what I did.
"Fabio was really fast in one part of the race, there was a gap in the middle but I caught up...amazing year, all the Repsol Honda team did an amazing job."
The Spaniard has now won nine races this season, including the last three in a row, with 14 podium appearances. His eight world titles include six MotoGP, a 125cc (now Moto3) title in 2010 and Moto2 title in 2012.
The MotoGP season continues in Japan on the 20th October.
