Sebastian Vettel held off his Red Bull teammate Mark Webber to win the Malaysian Grand Prix on Sunday.
The three-time defending champion battled with the Australian for much for the race before claiming victory.
Vettel complained to his team about Webber's slow pace earlier in the race, though both were tight throughout.
Both racers' cars were almost touching as the German took the lead on the 46th lap for his 27th win.
2008 champion Lew Hamilton came in at third ahead of his teammate Nico Rosberg, while Ferrari's Fernando Alonso has a poor day, crashing out of the race on the second lap.
