Jenson Button claimed his third win in four races in the Bahrain Grand Prix.
Sebastian Vettel (Red Bull) had to settle for second after losing time behind slower cars, whilepole-sitter Jarno Trulli (Toyota) was third and Lewis Hamilton fourth for McLaren.
A second lap pass on Hamilton proved critical to Button's victory for Brawn GP. Hamilton had used his McLaren's KERS advantage to blast past both Button and Vettel off the line, and also briefly passed Trulli, who had dropped to second behind team-mate Timo Glock at the start.
But Button drafted Hamilton on the pits straight and then passed the Toyotas by lapping faster ahead of his first pitstop.
