Nico Rosberg has emerged as the man to beat in qualifying for the Bahrain Grand Prix on a morning when a full complement of cars again took to the track.
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 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.
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.
