The weather may have been predictably unpredictable, but the racing at Silverstone was anything but 'to the form book' as Loris Baz and Sylvain Guintoli wrapped up two very popular victories in front of the British fans.

Indeed, while this year's WSBK season has certainly been more open than in previous years, you would have gotten good odds on Baz - in only his sixth WSBK event - and Guintoli - making his debut with PATA Racing following his split with Effenbert Liberty - to take the spoils.

Weather assisted or not, both riders were in imperious form on the way to their respective wins, with Baz emerging as the true star for his brave performance in race one, while his second place in race two proved he can podium in the dry, in the wet and even when he has dry weather tyres on a wet circuit!

In a way it is a shame Guintoli's achievement has been diluted by half-points being awarded for the race stopping early - particularly after an erroneous tyre choice in race one left him outside the top 15 - but his achievement is no less impressive.

At the sharp end, while neither commanded much attention in either race, Max Biaggi and Marco Melandri are at loggerheads off the circuit courtesy of Aprilia's protest [see separate story], but as things stand the latter has reduced his rivals margin to an increasingly slender 10.5 points with four rounds remaining.

Tom Sykes, Carlos Checa and Jonathan Rea hold firm in third, fourth and fifth, while Michel Fabrizio is the only top ten mover after rebounding from 11th to eighth courtesy of his race one podium.

With three podiums in four races, Baz has jumped to 13th overall, while strong results for Ayrton Badovini (third in race one) and Maxime Berger (fifth in race two) have nudged the unlucky Leon Camier to 16th, the Suzuki rider unrewarded for his pace after a crash and a technical failure.

In the manufacturers' standings, BMW have stretched ahead of Aprilia, though they have Fabrizio on the satellite S1000RR to thank this time for the extended 13.5 point lead.
