The victory was a landmark 70th for Lewis Hamilton, who is well on his way to a fifth title and is now 21 wins behind the all-time record of 91 held by seven times champion Michael Schumacher
Valtteri Bottas moved aside to let Mercedes team mate Lewis Hamilton win the Russian Grand Prix and surge 50 points clear in the Formula One championship Sunday with five races remaining.
The victory was a landmark 70th for the Briton, who is well on his way to a fifth title and is now 21 wins behind the all-time record of 91 held by seven times champion Michael Schumacher.
Hamilton's closest rival Sebastian Vettel finished third for Ferrari with Bottas, who led from pole position but was told to let Hamilton through after 25 of the 53 laps, securing the Mercedes one-two.
In a race with little other drama, Max Verstappen celebrated his 21st birthday in style by steering his Red Bull from the back to the front, dropping back to fifth after finally pitting with 10 laps to go.
Mercedes remain unbeaten in Russia, Sunday being their fifth win in Sochi since the Olympic Park circuit first appeared on the calendar in 2014. Hamilton has now won eight races this season.
The Briton, who pulled off an impressive overtake on Vettel for fourth after he dropped behind the German at the pitstops, stayed in the car for some time after he parked up at the finish.
He then went over to thank Bottas and commiserate. At the podium ceremonies, with Russian president Vladimir Putin doing the honours, Hamilton manoeuvred the Finn onto the top step alongside him.
The Finn, without a win this season, had asked the team over the radio, more in hope than expectation, in the closing laps whether the order might change back.
