Nico Rosberg maintained Mercedes' dominance with the fastest time in practice ahead of Saturday qualifying for the Formula One season opener in Australia. The German dashed around Melbourne's Albert Park street circuit in a best lap of one minute 29.375 seconds, 1.391sec ahead McLaren's Jenson Button. Rosberg's teammate Lewis Hamilton, who was fastest in Friday's practice, was fourth quickest (1:30.919), behind Fernando Alonso of Ferrari. Hamilton and Rosberg have been tipped to fight it out in Sunday's race, given Mercedes' superior pre-season testing and adjustment to rule changes, which include a fuel limit.
