Formula One championship leader Lewis Hamilton has taken pole position for the inaugural Russian Grand Prix.

Hamilton earned his sixth pole of the season by beating Mercedes teammate Nico Rosberg by two-tenths of a second in Saturday's qualifying.

Williams driver Valtteri Bottas was faster than Hamilton in his last lap but then went off in a corner briefly and stayed third.

Hamilton leads Rosberg by 10 points and is seeking his ninth win of the season. He has won the last three races and Mercedes can wrap up its first constructors title if one of its drivers wins Sunday's race.

Four-time defending champion Sebastian Vettel failed to make the third and final qualifying session in his Red Bull.
