Another "interesting" Ferrari strategy choice, sticking Raikkonen on super-softs and going three-stop. Let's see.
David Nicholson-Hirst: Hamilton managing his tyres, practically cruising in a F1 race car, this needs to change, shouldn't happen, this isn't excitement.
Daniel Tilling: Rosberg if he does win the championship would have only done so threw Hamilton's failures. Hammertime Hamilton.
Well it's not a race that, so far, will live long in the memory but it's the perfect race for Lewis Hamilton. He's comfortable out in front, nine seconds ahead of Daniel Ricciardo.
Kimi Raikkonen makes his second stop of the race. He swaps the softs for super-softs and with 32 laps to go, he will have to pit again. He's back out in sixth, one place behind his team-mate Sebastian Vettel.
Nico Rosberg, who is the only driver inside the top eight on mediums, is making ground on Daniel Ricciardo. The gap between himself and the Australian - who is second - is now 0.8 seconds.

Despite Max Verstappen's insistence that he is "not here to finish fourth" he appears to have backed off a bit to look after his tyres. He's now 2.6 seconds behind Nico Rosberg in fourth.

Nico Hulkenberg qualified seventh but was first out of the race after an early collision involving Sebastian Vettel and Valtteri Bottas.
Hulkenberg tells BBC Radio 5 live: "I got blocked in, I had Seb on my outside, and he turned into me quite harsh and I couldn't go anywhere as I had Valtteri inside me.
"Sometimes Vettel is quite aggressive and sometimes he forgets there are other cars. We all want to survive.
"I'm frustrated. You put in all the hard work over the weekend then something like this happens after five seconds of the race and it is tough to understand."
Jenson Button gets the edge on Daniil Kvyat at Turn 12 and the McLaren is up into 10th. Kvyat is one of two drivers yet to pit - along with Felipe Nasr. The Russian has a 10-second time penalty to serve as well.
"I'm not here to finish fourth," snarls Max Verstappen over the radio. He's feeling racey.
Nico Rosberg is the meat in a Red Bull sandwich at the moment. His target is Daniel Ricciardo but Max Verstappen is giving him food for thought. The Red Bull is just 0.7 seconds behind the Mercedes.
Meanwhile, Esteban Gutierrez is indeed out of the race, making him the second driver to retire today.

There's a problem for Esteban Gutierrez. He pits and that looks like it is race over for the Haas. A big shame for American-owned team.

Lewis Hamilton leads Daniel Ricciardo by 4.7 seconds, with Nico Rosberg 1.5 seconds behind Ricciardo in third.
Jeremiah Kariuki: Verstappen has gone past Kimi. Verstappen will be chasing Rosberg now. Nico has to be looking at his mirrors now. Not easy.
Guy Masters: Rosberg liable to fumble under pressure. If he can hold it together now he deserves to be world champion.
Sebastian Vettel pits from lead and is back out on softs. So, after the first lot of pit stops the top of the order is:
1) Hamilton 2) Ricciardo 3) Rosberg 4) Verstappen 5) Raikkonen 6) Vettel 7) Massa 8) Sainz 9) Kvyat 10) Alonso
