Lewis Hamilton produced a masterful drive to win Sunday's 2009 Singapore Formula1 GP from Timo Glock and Fernando Alonso as Jenson Button got more points on the board to shore up his championship lead.

Starting from pole, Briton Hamilton led from start to finish in difficult driving conditions to take the chequered flag in his McLaren, 9.6sec ahead of Glock and his Toyota.

It was Hamilton's second win of the 2009 season, after Hungary, and the 11th of his career.

Spain's Alonso, who won here in 2008 in controversial circumstances when Nelson Piquet deliberately crashed, brought some cheer to Renault with a hard-fought third to make the podium again

.

It left Germany's Sebastien Vettel to take fourth but it could have been much better. The Red Bull driver was second and in a close-fought battle with Hamilton but after pitting for a second time on lap 39, exited too quickly and incurred a drive-through penalty.

At least he finished one place ahead of championship leader Button, but with only three races left the gap between the two is 25 points and Vettel's chances of catching the Briton are slim.

Button now has 84 points with his Brawn GP team mate Rubens Barrichello 15 behind after ending sixth here under lights.

Heikki Kovalainen, in the second McLaren, was seventh and BMW's Robert Kubica eighth.

The Brawn pair now seem certain to deliver the Constructors' championship to their eponymous team chief Ross Brawn in the outfit's first season, with one of them being crowned World champion

.

The front row of the grid was always going to be decisive on the bumpy Marina Bay street circuit, where overtaking is difficult, and Hamilton made the most of starting on pole. Driving with aplomb and assurance on a track that demands precision, nerve, and confidence, he came through the opening corner scramble in prime position.

Nico Rosberg got past Vettel to second and Alonso had a storming start, powering to fourth from fifth, but by the end of lap one the Spaniard was down to sixth with Mark Webber and Glock getting past him. Button was up one place to 10th and Barrichello was seventh.

Webber was subsequently asked by his team to move aside and let Glock and Alonso back past him as his overtaking move on that opening lap was deemed illegal as he marginally left the track.

Hamilton and Rosberg were trading fastest times but by lap 10 the Briton was 2.2sec clear and more than 10sec ahead of fourth-placed Glock. Vettel was the first to pit from third on lap 17, followed by Rosberg and Hamilton four laps later. It was bad re-entry by Rosberg, who clumsily bounced over a painted line on his exit and was handed a drive-through penalty.

HALF-SECOND LEAD

Just minutes later and Force India's Adrian Sutil spun and then slammed into Nick Heidfeld's BMW Sauber as he attempted to get going again, leaving the track littered with debris and bringing out the safety car.

When the race resumed Hamilton had only a half-second lead on Rosberg, then Vettel, Glock and Alonso. Barrichello was sixth and Button was up to eighth.

When Rosberg went in to serve his penalty the top 13 all moved up a place with the German dropping down to 14th. It set the scene for a dramatic second half of the race: Hamilton and Vettel pulled away from the pack and, with less than a second separating them, it looked like an exciting finish.

But Vettel pitted again on lap 39 and pushed too hard coming out, speeding in the pit lane to be slapped with a drive-through penalty, ruining his night. Hamilton made no such mistakes and cruised on to a well-deserved victory. - AFP
