Having got himself up into the top 10, Sebastian Vettel pits to stick on the nippy ultrasofts. He resumes in 12th and is the fastest man through the first sector...
Lap 24/61
Lewis Hamilton: "You need to come up with some plan to stop me losing third because this is all I've got with these brakes."
Hamilton lead over Kimi Raikkonen is down to 1.1 seconds now...
Felipe Massa fancies getting involved in the Max Verstappen-Daniil Kvyat battle. He is 1.5s behind Verstappen and closing in.
Rachel T: No offence Max boy, but I think we're all cheering for @Dany_Kvyat, external at the moment.
Phil Slocombe: Nico only wins from the front; will have problems if a safety car closes them up.
A marshal nips onto the circuit to deal with that bit of debris. Fortunately, there is none of the drama from earlier in the race when a marshal (below picture) had a bit of a close shave.

You'd expect Ricciardo to move to ultra-softs at the end of the race, to take the fight to Rosberg if he can.
Lap 22/61
Daniil Kvyat has channelled his inner-Gandalf as he continues to deny Max Verstappen the chance to pass him.
Meanwhile, a bit of debris has cropped up at Turn 22 and double yellows are waved.
Kimi Raikkonen, currently fourth, is lapping quicker than both the Mercedes. He shaves a couple of tenths off of Lewis Hamilton's advantage is 2.3 seconds behind the reigning world champion.
Nick Hughes: Fantastic driving by Kvyat! Verstappen can dish it out but can't take it!
Benedict Salido: Max having a taste of his own medicine, and now he complains? Hypocrite.
Sam Payne: Verstappen getting a taste of his own medicine from kvyat! Love it.
Max Verstappen does not like the taste of his own medicine. He tries again at Turn 7, but once again Daniil Kvyat holds him off superbly. Great battle!
Meanwhile, Nico Rosberg is sitting pretty out in front. He leads Daniel Ricciardo by six seconds.
Paul Thompson: There has to be fallout with that near-miss with the marshall? F1 already has safety issues without causing themselves more problems.
Dom Uorri: HAM complaining & blaming team when not winning, who'd have thought it?
Now this is a fascinating tussle. Daniil Kvyat is defending from Max Verstappen, the man who replaced him at Red Bull. Nothing, and I mean nothing, is going to stop Kvyat from doing all he can to shut the door on Verstappen.
Verstappen attacks down into Turn 7 but Kvyat runs him wide. "Come on man," complains Verstappen.
Kimi Raikkonen is onto softs and back out in fourth. Just three cars behind him is Sebastian Vettel, who has done a superb job of recovering from starting at the back of the grid.

The gap is the full length of the pit straight and that's a big gap for Ricciardo to close.
Now Nico Rosberg pits from the lead and also goes onto the softs. It's a bit of a slow stop and he is back out comfortably ahead of Daniel Ricciardo.
Kimi Raikkonen is the current race leader but should be pitting again soon.
Interesting move by Mercedes. Lewis Hamilton is the first of their drivers to pit and he swaps the ultrasofts for the softs.
He doesn't seem happy about going on to the slower tyres. "Come on guys, I need a strategy where I can overtake," he says.
Daniel Ricciardo also pits, and there's certainly no problem from him with his team's strategy as he fist pumps a mechanic while a fresh set of supersofts are bolted on.
Another lap, another car picked off by Sebastian Vettel. He passes Felipe Nasr and is into the top 10.
Meanwhile, Fernando Alonso heads in from fifth to ditch the ultrasofts and switch to supersofts.
You can listen to Radio 5 live sports extra commentary of the start-line crash that eliminated Nico Hulkenberg above.
Lewis Hamilton (currently third): "Can you keep me up to date, please? I've no clue what's going on."
Red Bull started this race on the supersofts and Max Verstappen has decided to pit to pop on a fresh set. He's back out in 14th, behind Esteban Ocon.
