Button on pole again

Jenson Button set a searing pace once again for Brawn GP as he secured pole position for the Formula One newcomers in the Malaysian Grand Prix.

The British driver clocked a time of one minute 35.181 seconds to secure the fifth pole position of his career and his second in as many weeks.

Jarno Trulli will line up alongside Button on the front row of the grid after finishing second with a lap of 1min 35.273sec in the closing seconds.

Timo Glock recorded only the fifth best time in final qualifying but will be third on the grid in his Toyota as a result of penalties handed out to Sebastian Vettel and Rubens Barrichello.

Lewis Hamilton's miserable week continued with the world champion due to start 12th after failing to negotiate the second stint of qualifying.

But perhaps the biggest surprise was Felipe Massa, who will start near the rear of the field in 16th after failing to get his Ferrari through the first qualifying period.

Button claimed to be less than happy with his car after Friday's practice sessions but the 29-year-old was delighted with adjustments made to it overnight.

"Yesterday (Friday) I was really struggling with the balance of the car. I had a lot of rear locking and instability, and when I have that it's not my forte really because I find it difficult to drive it around," he said

"So we changed it around overnight and it's improved it a lot and I feel very comfortable in the car, so it makes it exciting."
