Jorge Lorenzo has won the 2010 MotoGP World Championship after finishing third in Sunday's Malaysian Grand Prix at Sepang.
With Dani Pedrosa missing the race due to injury, the Fiat Yamaha rider, winner of seven of the 15 races so far this year, only needed to claim ninth place to become champion with three rounds still to go.
Lorenzo led the early stages of the race before settling for a safe third behind team-mate Valentino Rossi (1st) and Andrea Dovizioso (2nd).
Rossi stopped to shake hands with Lorenzo as he celebrated on track. Lorenzo held a card saying 'Game Over'.
Lorenzo later got his Spanish flag caught in the rear chain on the slow down lap and had to seek assistance from marshals.
Lorenzo is Spain's second premier-class champion, after Alex Criville in 1999. His title is Yamaha's fifth since the switch to four-strokes in 2002 - the others being won by team-mate Valentino Rossi (in 2004, 2005, 2008 and 2009).
2010 is Lorenzo's third season in MotoGP, all of which have been spent with Fiat Yamaha.
The 23-year-old Mallorcan recently signed for two more seasons at the factory M1 team. Lorenzo will be joined in the team by Ben Spies next year, when Rossi's moves to Ducati.
Lorenzo previously won the 250cc world championship in 2006 and 2007.
