Lewis Hamilton cruised to victory in the inaugural Russian Grand Prix on Sunday, leading a 1-2 finish for Mercedes that clinched its first constructors' title.

Nico Rosberg placed second despite having to pit early in the race but now trails his teammate by 17 points in the drivers' standings, with three races remaining.

Hamilton won his fourth straight race and his ninth of the season.

The Briton lost the pole when Rosberg cut a corner and pushed past at the start of the race but Rosberg braked hard in the second turn and had to come in for a set of new tires. They lasted him until the end as he fought his way from the back of the pack.

Valtteri Bottas was third in a Williams.
