Lewis Hamilton, Nico Rosberg and Valtteri Bottas, one, two and three respectively on the timesheet, are back in the pits. They've done enough to get through.
Improvements from Sergio Perez and Nico Hulkenberg see them leap up to fourth and fifth.

At the moment, Jenson Button, Will Stevens and Roberto Merhi are in danger of being eliminated. Max Verstappen and Daniel Ricciardo are yet to set a timed lap, but are getting ready to head out for what is looking like one crack at getting through.
