 Button first managed to find his way past Barrichello on the last lap, then, at the penultimate corner, boxed Heidfeld in behind Sato, taking fourth.Barrichello then braked too late at the same corner, running into the back of Heidfeld, knocking the BMW Sauber's right rear wheel askew and damaging his own front wing.This allowed de la Rosa through to take fifth, Barrichello sixth, and the furious Heidfeld limped home seventh.
