Felipe Massa took sixth, as Williams look more competitive around one of their strongest circuits with Fernando Alonso, who had a hydraulic problem in Practice 1 and missed much of Practice 2, was able to finish seventh 0.2 seconds adrift of his former team-mate.

The two Saubers completed the field with the McLaren of Stoffel Vandoorne in between Marcus Ericsson in 18th and Pascal Wehrlein in 20th.
