Wandsworth's push for overall London Youth Games gold continued to gather pace this week as they won three more medals.

There was double success in the volleyball tournament as Graveney School defended their girls' title while Ernest Bevin College scored a repeat gold in the boys competition. Meanwhile, the borough's boccia team won silver.

It keeps Wandsworth, last year's runners-up behind Croydon, 27 points ahead of Ealing at the top of the standings so far this year.

After easing through the group and knock out stages, Ernest Bevin won their title by beating Hollyfield School of Kingston 25-14 in the final.

Graveney were equally dominant in their passage through the girls' competition and smashed Cardinal Wiseman of Ealing 25-3 in their final.

"They had my words ringing in their ears. You win and lose on serve receive and our training always reflects that so that was the key," said Graveney team manager Carlos Johnson.

"I think the School Games adds another layer of competition which exposes a broader number of players to volleyball. A minority sport like volleyball needs competitions like this and even at primary level to improve participation."

Ernest Bevin's team manager John Lowney said: "It’s a priority sport at our school and it’s obviously manifested itself over the last two or three years. We won this event last year so it’s a continuity and a commitment by our school to flag volleyball as a major sport.

"I don’t think we’d have had as many teams entered as we had this time no question about it. The question is how we develop that legacy and with the right type of structure there’s every reason to believe we could become a major sport in this country.

"You can’t expect a sport like volleyball, which has come from nowhere, to get to the standard we want it to so it takes time. All the indoor sports will develop as a result of the Olympics so as far as I’m concerned this  has been a real fillip for participation."

Wandsworth's boccia team were agonisingly close to gold but lost to Lewisham in the final on a sudden death point after the scores were level 1-1 after two ends.

Team manager Tim Richmond said: "The team exceeded expectations – they were fantastic.

"They all put in a really great effort, and they are really happy with their silver medals. They are all visually impaired so the braille on the medals is really extra special as well.

"The children are absolutely delighted, they got tired towards the end as it was a long day.

"The final was tense as it went to sudden death so they did really well to maintain their concentration.

"It’s great for the children to meet new friends as well as experience the competition environment."

The Games feature 85 competitions across 33 sports culminating in finals week at the National Sports Centre in Crystal Palace in July.
