Lewis Hamilton edges closer to his third Formula 1 world championship by dominating the Russian Grand Prix following the retirement of his Mercedes team-mate and title contender Nico Rosberg.
The Mercedes driver went side-by-side with polesitter Rosberg on the rundown to Turn 2 on the opening lap, but Nico was able to keep the lead.
Then when the safety car was called into action for a first-lap collision between Nico Hulkenberg’s spinning Force India and an unlucky Marcus Ericsson, Rosberg encountered a problem with his throttle pedal.
He ran wide at Turn 2, allowing Hamilton to take the lead and then Valtteri Bottas into second.
Rosberg subsequently slowed, crawling back to the pits where he retired the Silver Arrows. This non-finish means he is now 73 points behind championship leader Hamilton with only one hundred still available.
As for Mercedes, the Brackley-based team will have to wait until at least Austin to unpack its constructors’ championship t-shirts as it failed to outscore Ferrari by the required three points.
It was Hamilton’s 42nd career win, putting him one clear of three-time world champion Ayrton Senna and level with Ferrari’s Sebastian Vettel.
Vettel finished in second position on track and moves into second in the drivers’ standings, though if Hamilton outscores Vettel by nine points and Rosberg by two in America he will be champion.
Force India’s Sergio Perez achieved Force India’s third-ever podium, after choosing to pit under a second safety car and running a long stint on the softs.
That safety car period had been caused when Romain Grosjean lost the rear end of his Lotus at Turn 3 and as he tried to corrected, the car wobbled the other way, sending him onto the marbles and into the barriers hard.
The Lotus driver walked away from the crash, but admitted he would probably feel a little sore the next day.
There was drama on the final lap, when Bottas passed Perez for third, with Ferrari’s Kimi Raikkonen following him through.
But Raikkonen then had a lunge at Turn 4, hitting Bottas at the apex and pushing the Williams into the barrier.
Raikkonen survived the damage to get to the finish in fifth, behind Williams’s Felipe Massa who produced a superb recovery drive from P15.
The race stewards confirmed they would investigate the collision between Raikkonen and Bottas.
Should Ferrari and Raikkonen get a time penalty, Mercedes would secure the constructors’ title. If not, then the US Grand Prix.
Daniil Kvyat finished sixth on his home track in the Red Bull ahead of Sauber’s Felipe Nasr and Pastor Maldonado’s Lotus.
McLaren scored points with both cars for the first time this season with Jenson Button and Fernando Alonso, celebrating his 250th Grand Prix weekend but 248th start, ninth and tenth respectively.
Toro Rosso’s Carlos Sainz was on course for a superb points finish having started at the the back of the grid after missing qualifying following a high-speed crash in final practice.
But Sainz appeared to suffer a brake problem, causing him to spin twice, once into the barriers, and then retire the car a few corners later with significant damage to the rear wing.
Team-mate Max Verstappen, who suffered a puncture on the first lap when clipped by the spinning Hulkenberg, was classified P11.
Ricciardo was on course to finish fourth, but pulled off track with six laps to go, suggesting something had broken on the suspension in the Red Bull.
The Manor-run Marussias of Roberto Merhi and Will Stevens completed the list of finishers at Sochi.
