Lewis Hamilton completed a clean sweep of fastest practice times in Bahrain as he once again headed Mercedes team mate Nico Rosberg on Saturday afternoon.
The pair were split by just 0.115s, as the Englishman continued to lead with 1m 35.324s and the German chased him hard with 1m 35.439s.
The big surprise was Sergio Perez’s smooth run to third for Force India which made him the only other runner to dip beneath 1m 36s. The Mexican’s 1m 35.868s left him just 0.544s shy of Hamilton, and six-tenths up on team mate Nico Hulkenberg, who managed 1m 36.455s in the sister VJM07.
