Williams performance chief Rob Smedley believes that they have narrowed the gap between themselves and Ferrari, after Valtteri Bottas came fourth in the Spanish Grand Prix.
The Finn held off a late charge from Ferrari's Kimi Raikkonen in Barcelona, and Smedley admitted that he is encouraged with the result.
He told reporters: "It was an important weekend for us that we were able to see that we could primarily keep pace with everybody. We have kept the gap with Mercedes and arguably moved closer to Ferrari, at least in this race. We are also a little bit further ahead of Red Bull.
"This is not a circuit we expected to suit us particularly well, so I think it's been a good result overall."
Williams sit third in the constructors' standings.
