Tommy Hill went a long way to stalling HM Plant Honda's momentum in the hunt for the British Superbike title by claiming his first victory in fourth months at Cadwell Park.

Despite his consistency, the Worx Crescent Suzuki rider has struggled to match a charging Josh Brookes and Ryuichi Kiyonari in recent rounds in terms of raw speed, but was tough to match in race one.

It was Brookes that led from the start, but Hill remained on his tail until the eighth lap when he made his move for the lead before holding on to win.

Brookes's challenge would be nothing more than close contact, the Australian and his team-mate crossing the line to complete the podium. The Japanese rider had been as low as sixth at one stage before battling his way back up to third.

A strong event for the five confirmed title contenders, Michael Laverty and Michael Rutter completed the top five positions.

Rutter had initially been in the leading group but he later dropped to fifth place on the Ridersmotorcycles.com Ducati with James Ellison bringing the Swan Honda home in sixth position.

Yukio Kagayama fought his way through to seventh on the second of the Worx Crescent Suzukis after getting the better of Alastair Seeley, who scored another top eight finish. Seeley moved a step closer to becoming the final title contebder as rival John Laverty was involved in a collision with Tommy Bridewell on the final lap and crashed out at Barn.

Bridewell was later disqualified, to promote Dan Linfoot and Stuart Easton into the top ten.
