Sochi, Russia - Williams driver Felipe Massa was fastest in the second practice session on Friday ahead of the 2015 Russian GP, as the Sochi race track was plagued by rain.
Only eight drivers posted times during the afternoon session. Massa was fastest followed by Ferrari's Sebastian Vettel (2min00.659) and Massa's team mate Valtteri Bottas (2min00.688) who managed to shunt his Williams around the damp track to grab the third fastest spot.
Diesel spillage
The first practice session was marred by a diesel spillage from a circuit cleaning vehicle which delayed and curtailed opening free practice session.
