CRYSTAL Palace diver Jessica Williams celebrated a brace of silver medals at the 2010 British Gas National Cup in Sheffield at the weekend.

Her silver medal in the senior three metre springboard competition, gave the 15-year-old Townley Grammar School pupil enough points to qualify for the international Grand Prix competition in Rostock, Germany later this month.

Jessica also won a silver medal in the three metre synchronised diving competition on her debut outing with partner and Beijing Olympic finalist, Hayley Sage.
