SOCHI (REUTERS) - Lewis Hamilton won the inaugural Russian Formula One Grand Prix and extended his championship lead on Sunday in a Mercedes one-two that clinched the team's first constructors' title.

The Briton, who started on pole position, chalked up his fourth win in a row and ninth of the season to forge 17 points clear of German team-mate Nico Rosberg with 100 still to be won.

Hamilton, the 2008 world champion, also became only the fourth driver in F1 history to win nine races in a single season.

Finland's Valtteri Bottas finished third for Williams in a race watched by Russian President Vladimir Putin at a circuit snaking around some of the landmark venues from this year's Winter Olympics.
