THAILAND - Honda's Marc Marquez sealed his sixth MotoGP title, and eighth world championship overall, after winning the 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.
