Lewis Hamilton wins Singapore GP with Jenson Button fifth and Rubens Barrichello sixth
McLaren's Lewis Hamilton claimed his second win of the Formula 1 season in style as Red Bull's Sebastian Vettel handed his Brawn title rivals a boost, BBC reported.
A penalty dropped Vettel from second to fourth, just ahead of Brawn's Jenson Button and Rubens Barrichello.
The error leaves Vettel 25 points behind Button in the standings with 30 points remaining on offer. Barrichello is 15 adrift of his team-mate.
Toyota's Timo Glock took second place ahead of Renault's Fernando Alonso.
However, the finer details of the podium paled in the face of developments in the drivers' championship.
Vettel set off in hot pursuit of Hamilton after an early challenge from Williams' Nico Rosberg faded, but squandered his hard work when he broke the pit lane speed limit during his second stop for fuel and tyres.
As if the resulting drive-through penalty were not enough, Vettel also damaged his diffuser on a kerb.
