Pastor Maldonado had appeared on course for Williams' first points of the year, only to be robbed by a faulty tyre change at his final stop. The Venezuelan eventually sunk to 15th, behind Esteban Gutierrez and ahead of Williams
team-mate Valtteri Bottas while Charles Pic
overcame his own gremlins to win the battle of the backmarkers ahead of Caterham team-mate Giedo van der Garde and Marussia's Max Chilton.
Vettel's victory - his fourth of the year – re-established his advantage over Alonso to 34 points, with Red Bull
enjoying a 67-point cushion over Mercedes in the constructors' table heading into a three-week break before Hungary.
