Shane Byrne extended his lead in the British Superbike Championship with a pair of second places in the wet at Cadwell Park on Bank Holiday Monday.

Sittingbourne rider Byrne was runner-up to debutant Tommy Bridewell in the opening race which was red-flagged after eight laps due to heavy rain with the pair side by side.

Closest title rival Josh Brookes was fourth, while Ryuichi Kiyonari retired.

Race two was also won by a rookie rider, with Peter Hickman beating Byrne by almost three-and-a-half seconds.

Brookes was black-flagged and Kiyonari crashed out, leaving Byrne 96 points clear in the standings.

Byrne said: "I could see Josh had a black flag and I knew Kiyo had gone out, so second was a really good result for me."

Round nine takes place at Donington Park on September 7.
