for full FP3 times.
Lewis Hamilton was comfortably fastest in final practice for the Russian Grand Prix despite a spin which ended his running early.
Having already posted an impressive 1:38.726, Hamilton was on his second flying lap on soft tyres when his Mercedes snapped away from him approaching the penultimate corner, leading him to spin sideways off the track. Having ruined his tyres in the incident, Hamilton limped in to the pit lane and didn't re-emerge, but his time was not bettered.
Nico Rosberg was predictably second quickest but the best part of 0.3s slower than his team-mate, and he had Valtteri Bottas for close company with the Williams only 0.081s further adrift of Rosberg's time.
However, those were the only two drivers to get within a second of Hamilton's time, with Daniel Ricciardo fourth fastest ahead of Felipe Massa and Daniil Kvyat. Kimi Raikkonen, Fernando Alonso, Jean-Eric Vergne and Sebastian Vettel rounded out the top ten, with fourth to ninth covered by 0.4s.
After an encouraging Friday for McLaren, Saturday did not start in encouraging fashion as Kevin Magnussen stopped on track at Turn 5, bringing out the red flags after 18 minutes of the session. And FP3 didn't get much better as team-mate Jenson Button finished in 11th place despite having been so optimistic after Friday's running
McLaren confirmed after the session that it was a gearbox problem that had halted Magnussen, and with a new gearbox required he will join Nico Hulkenberg in taking a five-place grid penalty after qualifying.
There were also reliability problems further down the field too, with the sole Marussia of Max Chilton having driveshaft issues which the team is working on ahead of qualifying. That left him with the slowest of the times posted, with only Pastor Maldonado below him on the timesheets as Lotus found an ERS problem which required a battery change, ending Maldonado's session after two laps.
