Rosberg fast again in Bahrain
Nico Rosberg has emerged as the man to beat in qualifying for the Bahrain Grand Prix on a morning when all the cars again took to the track.
On Friday, Force India pulled Nico Hulkenberg and Paul Di Resta from FP2 for safety reasons after four members of the team were caught up in a petrol-bomb incident on Wednesday.
Both men returned to action at the Bahrain International Circuit on Saturday in the final hour-long practice session, but were well off the pace set by Rosberg.
After claiming his maiden pole and race win in China last weekend the confident 26-year-old has now been quickest in the final two practice outings for Mercedes.
However, his time on Saturday of one minute 33.254secs was almost four tenths of a second off his best on Friday, but still 0.147secs ahead of reigning world champion Sebastian Vettel.
With Red Bull looking stronger in Bahrain than they have in the first three races, Mark Webber was third quickest, 0.409secs adrift, with Lewis Hamilton fourth in his McLaren 0.528secs down.
Mercedes' Michael Schumacher was hot on the heels of Hamilton but, like the Briton, also half a second down, with Jenson Button down in sixth.
Lotus duo Kimi Raikkonen and Romain Grosjean were seventh and ninth, sandwiching the Toro Rosso of Daniel Ricciardo, with Ferrari's Fernando Alonso 10th but struggling 1.641secs behind Rosberg.
As for Di Resta and Hulkenberg, they were 15th and 19th, two and 2.5secs adrift respectively, with Ferrari's Felipe Massa a lowly 16th as the Brazilian continues to languish.
