FP2: Rosberg shines under lights

As night fell over the Sakhir circuit, Nico Rosberg came to the fore with the Mercedes driver edging team-mate Lewis Hamilton in FP2.
Unlike in FP1 when Mercedes did not factor, Hamilton was immediately involved in the night session, topping the timesheets on the medium tyres.
A swap to the softs saw his team-mate Rosberg come to the fore.
Chasing Hamilton around the track, the Brit clocked a 1:34.762 only to be beaten by Rosberg by 0.115s.
Ferrari dropped to third and fourth with neither Kimi Raikkonen nor Sebastian Vettel getting in clean laps on their first soft tyre lap.
The duo were both able to keep life in the tyres and posted a 1:35.174 and a 1:35.277 respectively.
Vettel's night, though, was not without problems.
Later in the session, putting in a long run, he reported a brake issue which ended with Sergio Perez clipping his front wing.
With debris on the track, the session was briefly red flagged to allow the marshals to clean up.
Valtteri Bottas was fifth for Williams ahead of Daniel Ricciardo and Pastor Maldonado. The trio all finished within a second of Rosberg's P1 time.
Felipe Nasr, Daniil Kvyat and Felipe Massa completed the top ten.
Over at McLaren, Fernando Alonso was P12, 1.544s off the pace, while Jenson Button had another stop start session due to an "anomaly" in Button's engine data.
He eventually completed 15 laps and was P19.
The only driver slower was Manor's Roberto Merhi, who was 5.945s slower than Rosberg.
