Mercedes divers Lewis Hamilton and Valtteri Bottas posted tenth and fourteenth fastest time. Hamilton set their best times earlier than most.
Daniel Ricciardo set third fastest ahead of his team-mate Max Verstappen. Sergio Perez ended the session fourth for Force India, with Williams drivers Felipe Massa and Lance Stroll following in fifth and sixth. Perez’s teammate, Esteban Ocon, was seventh.
