Hamilton keeps Vettel at bay to top final practice

Lewis Hamilton staved off a late effort by Sebastien Vettel to top the final practice session in Monza.

McLaren had dominated the session for most of the hour, with the team continuing to run different set-ups around the high speed circuit.

Although Jenson Button had topped the timesheets early on it was Hamilton, running without the F-duct, who eventually went fastest with a lap time of 1:22.498.

Hamilton’s time would remain unbeaten, finishing 0.226 seconds ahead of Vettel’s Red Bull.

Fernando Alonso had looked set to go fastest, sending his home fans into raptures in the dying minutes of the session as Ferrari dominated the times in the final part of the lap. The Spaniard may well have gone faster on his final run but was blocked by Kamui Kobayashi’s Sauber round the Parabolica, forcing him to settle for third.

Team-mate Felipe Massa was fourth, despite a huge moment which saw him spin into the Lesmo gravel, with Button and Mercedes’ Nico Rosberg rounding off the top sixth.

The session would proved to be yet another disaster for Mark Webber, who once again stopped out on track with a mechanical issue. The Australian’s Red Bull suddenly lost power at the Rettifilo – hampering his preparations for the rest of the weekend.
