"For all Lewis Hamilton fans, this is a beautiful thing. Is he at the top of his game? It's difficult to imagine he could climb any higher."
A different strategy in play at Red Bull as both Daniel Ricciardo and Daniil Kvyat take on softs.
Ricciardo is out in 10th, with Kvyat 12th.
Meanwhile, Lewis Hamilton's Mercedes is getting smaller as far as the rest of the field are concerned, his advantage now 19 seconds. Faultless from the Brit so far.
Reece Young: Has Hamilton dominated a race more than he is today? Perfection so far.
Vertically Challenged: Rosberg may be a good driver, but to become a great driver you have to learn to pass on track and pass well.

"Roberto Merhi was already locking up and completely caught out by Kimi slowing down as he entered the pit-lane. How close was that?"
Yowzer!!
Close, close shave for Kimi Raikkonen. He is called in but is almost struck by Roberto Merhi behind him, the later hitting the brakes hard to avoid impact.
The pit stop proves a smooth one after that drama and Raikkonen is back out in 10th, with medium tyres bolted on.
Nico Rosberg is rearing up and ready to pounce on Kimi Raikkonen. Rosberg is on the fresher tyres, so if he gets this right he should be able to pass without any drama.
Rosberg fancies it on the pit straight and breezes past.

"Hamilton is having a breeze of it - no challenge whatsoever."
A 2.7s stop sees Lewis Hamilton back out and comfortably in front again with medium tyres on his Mercedes.
Sebastian Vettel pits, takes on mediums and is out in 2.4s to retain second place ahead of his Ferrari team-mate Kimi Raikkonen.
"OK Lewis, box," Lewis Hamilton is then told over team radio.
Khan: If Hamilton wins then Rosberg is gonna have to go onto a crazy winning run to get momentum.
Reece Young: Has Rosberg ever made a pass on track? Seems to always rely on the undercut.
Mark Heath: Another strategy error from Williams?
Douglas D P Townsend: Well @McLarenF1, external might as well be powered by Mario's ice cream van. Clearly on a par with the #Honda, external
Both Red Bulls are in to the top 10, with Daniel Ricciardo eighth and Daniil Kvyat ninth.
Ricciardo, though, is closing on Sergio Perez...and passes him to climb up to seventh.
Up ahead, Lewis Hamilton's advantage is now up to 15 seconds, but Sebastian Vettel is about to pit...
Lewis Hamilton might be losing some grip but he is being kept out for now. He has told over team radio that he is matching Nico Rosberg's lap times, despite the latter being on fresh medium tyres.

"I'm not sure the reason for Williams to stay out longer with Valtteri."
Race leader Lewis Hamilton: "I'm losing grip on the front-left. I've got some understeer."
Valtteri Bottas is coming in now for his first pit stop. A nervy moment for the Williams team after mixing up compounds at Belgium last time out, but all good as mediums are bolted on without any bother and he is back out in seventh.

"Rosberg was able to go purple and purple in the second and last section and that was how he was able to get the undercut (on Massa)."
