Hi Jack!

Don't forget you can listen to live commentary online via the Live Coverage tab.

Stoffel Vandoorne is back out after his earlier problem and getting those much-needed laps in.

Meanwhile, qualifying sim o'clock for Nico Rosberg. He's got super softs bolted on to his Mercedes.

Ferrari have done plenty of long run work in practice. Perhaps they know they cannot out qualify Mercedes and are subsequently working on their race pace.

Look away now if you are following from somewhere where it is raining like, say, Manchester. Scorchio.

Twenty minutes left and we'll soon be approaching qualifying runs territory. Long run done for Sebastian Vettel as he pits.

The Toro Rossos, who have looked capable of challenging at the top end of the grid this season, are propping up the timesheet at the moment.

Max Verstappen is 21st, with Carlos Sainz 20th and there is a problem for the Spaniard. "OK I think I have a puncture of something," he reports.

McLaren raised a few eyebrows on Friday when Jenson Button set third quickest time in second practice. There were extenuating circumstances to an extent, in that he used the super-soft tyre later in the session than many, and so probably benefited from extra grip. 

Still, Daniel Ricciardo admitted he had not expected to them to be that fast, and the time was 0.3secs quicker than last year’s pole, which underlines the progress McLaren and Honda have made since last year. 

And something that did the same was to hear Button himself say he was aiming for a place in the top eight on the grid. "When you're third in FP2, and it's not because of changeable conditions or anything, you've got to be thinking about getting into Q3,” he said. “It has to be the aim."

Jenson Button is up and running with his first timed lap - a 1:35.782, which is almost three seconds slower than Kimi Raikkonen's benchmark time.

Esteban Gutierrez has his claws out.

"I have some traffic from Lewis," he says. "I don't know what he is doing, it was the same the other day."

Meow.

Not a cloud in the sky in Bahrain. Beautiful day.

Sebastian Vettel is working through a long run. He's on his 11th lap on the soft tyre, the most any of the drivers have managed on one set so far today.

We've had times from everyone except for Jenson Button and Stoffel Vandoorne so far.

Half an hour to go.

"Judging by the McLaren mechanics' expressions it looks good. I think Stoffel will be back out quite soon."

Valtteri Bottas slaps on the super softs and goes quickest of all, clocking 1:33.042. 

It is a brief stay, though, as Ferrari have come to the party. Kimi Raikkonen goes fastest of all with 1:32.863, and that's with soft boots on as well.
