WAGGA tennis prodigy Joey Swaysland has exploded on to the international sporting stage in a blaze of glory as Australia triumphed in the Junior Davis Cup final in Mexico.

The 16-year-old rising tennis star clinched the title for Australia by partnering Jason Kubler to win the deciding doubles match against Great Britain in San Luis Potosi yesterday.

The final was locked at one match-all before Swaysland and Kubler aced the doubles 6-1 7-5.

As Joey celebrated with teammates and captain Ray Ruffles in Mexico last night, his jubilant family in Wagga, including mother Jenny and father Rick, also savoured the magic moment.

The proudest mum in the Riverina, Jenny Swaysland yesterday described how the family had watched the defining doubles match on a live feed on the Internet.

"We haven't been able to speak to Joey yet," she told The Daily Advertiser yesterday.

"We are very proud; we are walking around on cloud nine at the moment."

Joey's mother said her son had now shared two remarkable victories in major international events.

"To be part of the team that won the under-14 year World Cup, and now for the boys to win the under-16 Junior Davis Cup, is just awesome." she said.

"It is a great reward for all the hard work of all the boys."

Australia lost the opening singles 6-4 6-4 against Great Britain, but Queenslander Kubler levelled when he beat George Morgan 7-6 7-5 in the second singles match

Joining Kubler in the doubles, Wagga's tennis tyro produced some fabulous shots to steer Australia to victory.

For Australia, it was the fifth win in seven Junior Davis Cup finals.

"It has been a big week for the boys," Jenny Swaysland said.

Joey had been "having a ball" in Mexico, according to his mother.

"I have seen pictures of them all wearing sombreros at a party organised for them one night," she said.

Recalling the decisive doubles, Jenny said the match was five-all in the second set before Joey and Jason Kubler broke the Great Britain serve.

"Jason served out the match," she said.

"Jason lives in Brisbane, but the boys are really good friends and play in a lot of tournaments together.

"We just can't believe it."

Before the final, the Australian team had spent a week in Palm Springs in California being coached by Mark Woodforde.

"They had five days in Mexico to acclimatise because it is high altitude," Jenny Swaysland said.

"The heat hasn't been too bad."
