If the first World Superbike race of the day at the Nurburgring went to the formbook, then the second race certainly threw it out of the window as Carlos Checa and Tom Sykes leave Germany as winners under two very different circumstances.

The pre-race withdrawal of Max Biaggi means Checa is looking increasingly likely to secure a first WSBK crown, the Spaniard's 11th win of the season proving little surprise to those that witnessed his superb Superpole performance a day earlier.

However, when the rain came, 'King Carlos' was a mere pawn as he favoured caution on the way to a very unspectacular eighth place. Despite this, his earlier success - and problems for others - means he still scored more points than any other rider in Germany, lifting his advantage up to 72 points now with six races to go and a maximum of 150 points available.

Marco Melandri is now his closest challenger in second having cracked the 300-point marker, while Biaggi will be close to conceding his crown as he slips just five points off a full ton behind Checa.

Eugene Laverty remains fourth after two more good top five finishes, while Leon Haslam will have surprised himself to increase his advantage over Leon Camier, despite crashes in both races.

Camier holds onto sixth, aided by Michel Fabrizio's failure to score in either race, but they are coming under pressure from the very consistent Sylvain Guintoli and Ayrton Badovini. Guintoli was one of the day's big winners with a run to second and sixth, placing him just 15 points behind Camier, while Badovini's 12th and 13th consecutive top ten finishes means he is just five points behind himself.

Noriyuki Haga holds down tenth after a strong ride to third in the first race, though his mind will be focused on the 25 he dropped when he fell from the lead in race two.

He also heads up a very tight group of riders all jostling for an overall top ten position, with just six points covering himself, Tom Sykes - up three places thanks to his surprise win -, Jonathan Rea, Joan Lascorz and Jakub Smrz, the latter recovering some much needed ground with third after retiring from seven of the last ten races.

Things have also stretched out in the manufacturers' standings, with Ducati now 49 points up on Yamaha, while Aprilia - suffering from Biaggi's withdrawal, despite Haga's best efforts - is now 64 points from retaining its title.

Behind them, BMW remain a lonely fourth, while Kawasaki is up to a new high of fifth following its win, ahead of Suzuki and Honda.
