Red Bull driver Daniil Kvyat posted the quickest time during a wet second free practice session ahead of the Japanese Grand Prix.
Kvyat clocked a time of 1:48.277 during the driest spell of running at Suzuka to finish 0.023s ahead of Nico Rosberg as the drivers were able to use Intermediate tyres.
Kvyat’s time came shortly before conditions deteriorated with half of the session remaining and followed on from a wet start to Friday, when Carlos Sainz Jr. went fastest in the opening 90 minutes in the morning.
World Champion Lewis Hamilton finished in third place, with Daniel Ricciardo in fourth for Red Bull.
Ferrari collected fifth and sixth courtesy of Sebastian Vettel and Kimi Räikkönen, while early pace setter Sainz was seventh.
His Toro Rosso team-mate Max Verstappen ran through the gravel trap at the hairpin on his way to eighth position, with Felipe Nasr moving up to ninth shortly before the rain intensified.
Lotus’ Pastor Maldonado survived a grassy excursion exiting the first corner to complete the top 10, ahead of Nico Hülkenberg, Jenson Button and Marcus Ericsson.
Sergio Pérez finished in 14th place, while Romain Grosjean returned to his E23 Hybrid after sitting out the first practice session in favour of reserve driver Jolyon Palmer, who was only permitted an installation lap.
Felipe Massa was 16th, while Fernando Alonso only joined the action once the rain returned and put his McLaren into 17th place.
Will Stevens and Alexander Rossi finished 18th and 19th; Valtteri Bottas opted not to run in the session in order to save his tyres.
Dry and sunny conditions are expected for the remainder of the weekend.
