Williams’ Felipe Massa set the quickest time during a low-key rain-affected second practice session ahead of the Russian Grand Prix.
A shower drenched the circuit shortly before the start of the session and the water was slow to shift, leaving only eight drivers to post nominal times across the 90 minutes.
Massa was the last driver to cross the line and clocked a 2:00.458, two-tenths clear of Ferrari’s Sebastian Vettel and Williams team-mate Valtteri Bottas.
Toro Rosso's Max Verstappen had been quickest until a late flurry of times, while Fernando Alonso was the only driver to brave the conditions early on, before being called into the McLaren garage over a suspected mechanical issue.
Daniil Kvyat, Carlos Sainz Jr. and Jenson Button were the only other drivers to post a lap time.
Both Mercedes and Force India drivers, along with Marcus Ericsson and Daniel Ricciardo, completed an installation lap but opted against full-scale running.
Lotus, Manor Marussia, Felipe Nasr and Kimi Raikkonen elected not to run in the session.
