If you had to put your life savings on it, you wouldn’t put it on Rosberg closing the gap to Hamilton.
Rosberg weaves across the track to get those tyres all zingy - and here he goes on a flying lap.
Lewis Hamilton comes out a few seconds later. So Rosberg will be able to set the time to beat.
Nico Rosberg is the first car back out. Can he take pole away from Hamilton in a session the Briton has dominated?
All the cars back in the pits with four minutes left - they'll have one more crack at a quick lap.
Just seeing why Gutierrez has yet to set a time. He misjudged a turns and slid on to the grass, scuppering his lap.
Bottas, Ricciardo, Verstappen, Hulkenberg and Perez round off the top nine in that order, with Gutierrez yet to set a time.
Rosberg made a mistake on his lap so he has a bit more time in his back pocket. He'll come again.
Raikkonen goes three tenths quicker than his Ferrari team-mate Vettel to take P3.
Hamilton next - he's 0.288secs quicker.
Catch that man if you can.
Rosberg is first over - it's 1:21.646.

Hamilton has the edge over Rosberg and Mercedes have more than the edge over the rest of the field.
Hamilton, Rosberg, Vettel, Raikkonen, Bottas, Ricciardo, Verstappen, Perez, Hulkenberg and Gutierrez are the men in contention.
All of them on super-soft tyres, of course.
Big round of applause for Haas who have Esteban Gutierrez into Q3.
Q3 - a top-10 shootout for 12 minutes to decide where you start on the grid.
Let's get it on.

I’ve just been looking at Lewis Hamilton and if that flat spot is as bad as it sounds, it really could prove to completely define his race because if it means that his first stint in the race is going to be shorter than Nico Rosberg’s then he’s going to have to switch on to the medium tyre, which he hasn’t had a chance to test.
That could prove a problem tomorrow.
Here is what Lewis Hamilton said on the radio midway through Q2: "I have a small flat spot on the right front but I'll go again if we have the tyres."
He did go back out, but couldn't beat his initial time.
The only way he can change tyres for the race is on safety grounds - and then it would have to be for a set of tyres of a similar age.
The word is that Lewis Hamilton may have put a flat spot on the tyres he used to set his quickest time - they're the tyres he must start the race with.

If you want a snapshot on the reason why Felipe Massa is retiring, there it is. He’s half a second behind his teammate on a track that isn’t that challenging for the drivers. He will be bitterly disappointed by that.
