Tom Sykes moved in to the lead of the World Superbike riders' championship after round 10 of the season at the Nurnburgring.

The Kawaksi rider won the opening race, which was cut short due to a red flag, to move ahead of Sylvain Guintoli at the top of the standings.

Guintoli finished fourth in race one and could only manage a fifth-placed finish in race two as Sykes took fourth to move one-point clear of the Aprilla racer.

The British racer's win came after a red flag brought the first race to an end as Jonathan Rea and Leon Camier both crashed on an oil spillage at turn nine and, although Marco Melandri was leading at the time, Sykes was handed the win as he led at the start of the previous lap.

Melandri's BMW team-mate Chaz Davies rounded out the podium in the first race before taking victory in race two.

Eugene Laverty finished an impressive second, just over one-tenth behind Davies, with Melandri taking his second podium of the day by finishing third.

But it was the battle below the top three that could prove pivotal with four rounds of the 2013 season remaining.

Both Sykes and Guintoli were in amongst the front runners during the early stages of race two with the former managing to finish fourth and score two more points than the Frenchman, who lost his position at the head of the standings.

The win was Sykes' sixth of the season whereas Guintoli has relied more on consistent points finishes, having only won the opening race of the season at Phillip Island.

Sykes will be hoping he has hit the front at just the right time with only four races, in Istanbul, Laguna Seca, Magny-Cours and Jerez, remaining.
