Sepang: Red Bull driver Mark Webber set the fastest time in Friday's practice sessions for the Formula One Malaysian Grand Prix, edging out McLaren's Jenson Button. (In pics)
Webber was just five hundredths of a second quicker than Button, with McLaren's Lewis Hamilton and Red Bull's Sebastian Vettel both within a quarter of a second — setting the stage for a qualifying clash between the top two teams on Saturday.
There was a gap between those drivers and the rest of the field on a humid but dry day at the Sepang circuit. Mercedes drivers Michael Schumacher and Nico Rosberg were fifth and seventh respectively, and Ferrari's Felipe Massa was in sixth.
