SAKHIR, Bahrain — Brawn GP's Jenson Button won the Bahrain Grand Prix on Sunday, giving the Briton his third win in the four Formula One races this year.

Red Bull's Sebastian Vettel was second, 7.1 seconds behind Button, and Toyota's Jarno Trulli, the polesitter, took third at the Sakhir circuit.

The result gives Button a 12-point lead in the drivers' championship, with a two-week break before the series heads to Europe.

"This race win for us is probably the best out of the lot, because we don't have a competitive edge," said Button, referring to his rival teams' recent improvement. "We are not as strong as we used to be and had to work doubly hard."

Defending champion Lewis Hamilton was fourth for McLaren, ahead of Brawn GP's Rubens Barrichello. Kimi Raikkonen finished sixth to give Ferrari its first points of the season, with Toyota's Timo Glock and Renault's Fernando Alonso seventh and eighth.

Button's key move was when he passed Hamilton at the start of the second lap, while Vettel got stuck behind the McLaren, which was slower through bends but hard to pass because of its KERS power-boost.

"That move really made the race for us," Button said.

Glock started on the outside of the front row and got the best of the start to lead Trulli in the early stages, and the Toyota teammates held that advantage until the first set of pit stops. However, Toyota's strategy to use the less-preferred medium-compound tire through the long second stint of the race gave a the advantage to Button, who effectively led from the 13th of 57 laps.

Button has 31 points from four races, putting him 12 points ahead of Barrichello. Brawn is well out front in the constructors' championship as well.

Ferrari's points avoided it going through the first four races of the season without a point for the first time in its F1 history.
