A euphoric Lewis Hamilton extended his world championship lead to 73 points on Sunday when he rode his luck to claim a strategic victory for Mercedes in a roller-coaster Russian Grand Prix.
The defending five-time champion came home 3.829 seconds ahead of team-mate and nearest championship rival Valtteri Bottas as Mercedes took advantage of Ferrari's reliability and tactical problems by delivering a Silver Arrows one-two.
Having grabbed the lead from pole man Charles Leclerc on the opening lap, Sebastian Vettel ignored team orders to let him pass before he suffered a mechanical failure and stopped on lap 28.
The resultant Safety Car period gifted Mercedes, who started on medium tyres while their rivals all used softs, a chance to extend their Sochi supremacy to six consecutive wins.
Leclerc came home a frustrated and disgruntled third, claiming he expected Vettel to repay him for his slip-stream in a race punctuated by two Safety Car interventions and one use of the Virtual Safety Car.
Hamilton's win was his first since the Hungarian Grand Prix on August 4, his ninth in 16 outings this year and the 82nd of his career, lifting him 73 points clear at the top of the drivers' title race. He scored an additional point for fastest lap.

"It's a shame for the team not to have both of us up here... I will always trust the team, but our tactic was for me to give the slipstream, which I did - and then, well I need to speak to the team about that."
"We will speak later, but now it is difficult to close the gap. Obviously."
