Mark Webber topped the second free practice session at Spa-Francorchamps in the build-up to the Belgian Grand Prix.
In a session where the Australian completed 22 laps, Webber notched up a best lap of 1:50.321 on the soft Pirelli tyres, before a steady fall of rain silenced proceedings.
Webber came away from the practice with 1.469 second advantage over Red Bull teammate Sebastian Vettel, although the reigning Champion’s best came via the slowing, longer-lasting medium compound tyre.
Fernando Alonso came close to placing his Ferrari at the top of the pile, with a time just 0.14 of-a-second shy of the Red Bull.
The Spaniard managed 18 laps over the changeable session, allowing himself to be the first to run on slicks in the early running.
The McLaren’s of Jenson Button (3rd) and Lewis Hamilton (4th) were next up, both of whom only ran nine laps apiece as they struggled to catch dry running.
Williams did not have the best of practices, with Rubens Barrichello found his FW33 shy of a working KERS unit. It did not stop the veteran from being only two-tenths shy of teammate Pastor Maldonado, following a 17 lap stint.
Vitaly Petrov had another tough session in his Renault. The Russian suffered from a pulling steering wheel, limiting him to only 12 laps in the early part of the session.
Petrov rounded out the timesheets – his best lap set at the session beginning in damp conditions – while new teammate Bruno Senna registered the 17th best time, before the rain fell.
