Valtteri Bottas was pleased with Williams' competitiveness during qualifying in Sochi after getting the better of both Ferraris.
Mercedes once again locked out the front row of the grid with Nico Rosberg taking pole position, but Bottas was the best of the rest as he was third fastest in Q3 after edging Sebastian Vettel by 0.053 with Kimi Raikkonen down in fourth place.
Bottas, of course, also started ahead of the Ferraris at the Japanese GP, but he finished behind both Vettel and Raikkonen during the race, something which he hopes to avoid come Sunday's Russian Grand Prix.
"It seems we have the measure of Ferrari – at least today," he said. "Today we were quite competitive and third is a good place to start. It has been tricky for everyone with limited practice."
Meanwhile, his team-mate Felipe Massa had a nightmare Q2 session and will start the race down in 15th place.
"I had two laps behind traffic and by the time I had a clear run my tyres had gone. It's really frustrating," the Brazilian said.
