@ankur: Earlier McLaren tweeted to say it hopes to get Alonso back out today but they're running out of time.
Vettel has made his way back safely to the pits as Sainz's broken down Toro Rosso is recovered from the track.
@Riccardo: We should get underway shortly.
Sainz has broken down somewhere in the middle sector.
@Lachuchelsea: Not yet, no. Will update you as soon as we hear anything.
@Eugene: They are using the chicane.
Green flags come out and Ericsson, Bottas and Rosberg all venture out. Ericsson is on soft tyres, while Bottas and Rosberg are on mediums.
@MrTuK: I like the narrow, compact McLaren this year.
Vettel also heads back out in that red car.
As rumoured, McLaren planning a new livery at some stage this season.
@Sash: Earlier on the team said it was dealing with a "niggly problem" that it hoped to resolve by the end of the day. At the moment, it doesn't seem they're going to get back out.
Remember what I was saying about headline times.... Ericsson goes second fastest on his latest soft tyre run, 0.087s off Vettel.
Ericsson could have gone P1 were it not for a mistake at the final hairpin, where he ran slightly wide.
@abhishek: 40 minutes left.
@abhishek: Rosberg is out on track on a longer run. As I keep saying, they won't be too obsessed with lap times today.
@ashish: The current black and white is only for testing as it stands.
Mileage for you: Rosberg (137), Bottas (56), Ericsson(54), Sainz Jr (46), Vettel (42), Ricciardo (35), Alonso (six)
@deepu @baffino: McLaren was dealing with "niggly" problems earlier and hoped it would rectify by the end of the day. It looks like they have been unsuccessful now though.
Rosberg enters the pits but goes straight through and back out to the circuit again, starting lap 141
@deepu: No idea, McLaren has not revealed any details further than just one tweet.
Bottas now the only man out on track.
