Jenson Button benefited from a typical piece of Ross Brawn strategy to come through from fourth on the grid to win the Bahrain Grand Prix.
The Briton, who lost out to countryman Lewis Hamilton at the start, made importantly short work of the world champion in the early stages to mark himself out as the main challenger to the front row-occupying Toyotas. Then, when the lighter Jarno Trulli and Timo Glock stopped before the Brawn, Button was left in prime position to claim a third - and potentially most satisfying - win of Brawn's maiden season.
Through the middle part of the 57-lap event, the two Toyotas fell further away, leaving Sebastian Vettel - with newer tyres and a heavier initial fuel load - as the only real threat to the championship leader, but Button had enough in hand to come home nearly ten seconds ahead of the field.
Vettel managed to resist a late spot of pressure from Trulli, to claim another podium to add to his win in China, while Hamilton managed to come home ahead of the second Brawn of Rubens Barrichello to collect a much-needed fourth place for the beleaguered McLaren team.
Even more desperate for a result, Kimi Raikkonen gave the visiting Luca di Montezemolo something to cheer with sixth for Ferrari, coming home ahead of the disappointing Glock, while Fernando Alonso held off Nico Rosberg for the final point.
The German's Williams team-mate, Kazuki Nakajima, posted the sole retirement of the hottest race of the year so far, but that will be of little comfort to the two BMW Saubers, both of which were hobbled by first lap contact that left them aerodynamically disadvantaged and switching to a one-stop strategy that failed to pay dividends.
