Felipe Massa topped the timesheets in a wet second practice for the Russian Grand Prix as just one of eight drivers to set a time.
After a diesel spillage prevented any meaningful running in first practice, rain ahead of FP2 meant drivers were unable to use slick tyres throughout the 90 minute session. The rain got progressively worse and the best times were set on full wet tyres as the drivers struggled.
The wet weather means there was no running on the super-soft tyre in FP2 and a very limited amount of laps on the soft tyre in FP1. As a result teams will go into final practice on Saturday morning with a lot to learn ahead of qualifying in the afternoon and Sunday's race. Six drivers opted not to leave the pits altogether, believing there was little reason to do so with rain not forecast again for the rest of the weekend. However, Toro Rosso signed off the session by telling Max Verstappen to save his tyres as they will "probably" need them for Sunday.
Neither Mercedes set a time, while Kimi Raikkonen was one of the drivers who failed to set a lap at all. In the final minutes of the session the track started to get quicker as a racing line formed for the wet tyres. Valtteri Bottas momentarily held the top spot when the chequered flag fell, before Sebastian Vettel and Massa knocked him down to third with their final laps. As he had in the morning, Fernando Alonso led the mileage counter with 12 as McLaren used the conditions to test its upgraded Honda power unit.
