Kimi Raikkonen picks off Nico Hulkenberg - yet to make a stop - at Turn One and the Ferrari is up to fifth.
Valtteri Bottas, on fresh super-softs, is the fastest man on the track as he does a 1:33.688. That's half a second quicker than Daniel Ricciardo, who is 10 seconds ahead of the Finn in third.
"Struggling with my rears," reports Lewis Hamilton.
Max Verstappen's eyes will be lighting up...

Valtteri Bottas has been the number two driver all year.
Lewis did have some difficulties early in the season but since the summer break it has been absolutely crystal clear.
Lewis stamped his authority on the championship and at Mercedes and left no one in any doubt that he is faster than Bottas.
Clear air now for Max Verstappen, who has 3.1 seconds to make up on race leader Lewis Hamilton.
Valtteri Bottas, meanwhile, is onto super-softs and back out in fourth, ahead of Kimi Raikkonen.

Sam Harris: I just woke up because I thought the race started at 7am
You've had a shocker, Sam.
A little lock up for Valtteri Bottas and Max Verstappen attempts to bounce but Bottas fends him off for now.
"Box, box, box," Bottas is told.
Kimi Raikkonen makes his first stop of the race, moving onto super-softs having started the race on softs. He's back out in sixth but Nico Hulkenberg, one place ahead of him, still needs to make his first stop.

That was quite clear, good, number-two driving from Valtteri Bottas.
Valtteri Bottas effectively moves aside to let Lewis Hamilton pass and immediately the Briton goes a couple of tenths of a second quicker than Max Verstappen to increase his advantage to 2.2 seconds.
Mercedes are keeping Valtteri Bottas out there for now. Is that wise? It's comprimising Lewis Hamilton's pace behind him and Max Verstappen is closing in...

Nico Hulkenberg locks up and goes off at Degner 2. He's into the gravel but keeps the Renault out of the wall.

Motor racing is unpredictable and Ferrari's engines haven't been durable enough. At this point in the season though, it could all change again.

Daniel Ricciardo pits from the lead. Softs on and he is back out in fifth, behind Kimi Raikkonen.
Sebastian Vettel, speaking to Sky Sports: "We have done an incredible job so far. Pity the last two races with reliability issues but it is like that sometimes. We are disappointed but we need to get some rest and go flat out for the next few races.
"We still have a chance this year. The team is in a good way, we are improving race by race. We got a lot further than people thought so there are some positives."
Max Verstappen is the fastest man on the circuit as he does a 1:33.813 and the gap between himself and Lewis Hamilton is 1.8s.
Those stops put Daniel Ricciardo into the lead but he will need to pit soon to bin the super-softs. Valtteri Bottas is also yet to make his first stop but, as he started on softs, his first stint will be longer.

That was a perfect stop for Lewis Hamilton.
Mercedes do respond and in comes Lewis Hamilton. Softs on and he is back out in third and stays ahead of Max Verstappen.
