LONDON, England (CNN) -- Rubens Barrichello beat teammate and Drivers' Championship leader Jenson Button as Brawn claimed a one-two at the Italian Grand Prix held at Monza.
Barrichello celebrates winning the third Italian Grand Prix of his career.
It was the Brawn team's fourth one-two finish of the 2009 season.
Lewis Hamilton led the race early on but a two-stop strategy saw him fall behind the two Brawns -- who were on a one-stop strategy -- in the second half of the race.
With laps running out Hamilton gamely tried to chase down second-placed Button, but the 2008 world champion pushed too hard on the final lap and spun off at the Lesmo turn to hand third place to Ferrari's Kimi Raikkonen.
Brawn's main rivals in the Constructors' Championship, Red Bull had a poor day as Mark Webber was forced to retire on the first lap, while Sebastian Vettel could only finish eighth, losing precious ground on both Barrichello and Button.
It was Barrichello's second victory this season and the third time he has won the Italian Grand Prix in his career.
Jenson Button secured his first podium finish since he won at the Turkish Grand Prix in early June.
It was another good day for the Force India team and in particular Adrian Sutil as the German finished fourth to claim the first five points of his Formula One career.
