SINGAPORE - South Africa's national team have a point to prove when they tackle the Singapore Cricket Club International Rugby Sevens (SCC 7s) at the Padang this weekend.

Having finished runners-up in the past three seasons of the World Rugby Sevens Series, the Springboks are gunning for the top spot at the 2015-16 campaign, which includes Singapore as a host leg.

The 2014 Commonwealth Games gold medallists last won the global series in 2009.

The SCC 7s is a prime opportunity for the South Africans to prepare themselves for the new season starting in December. It has been three years since they last competed in the iconic tournament.

The event returns for its 68th edition from Friday to Sunday, with 22 teams from 11 countries looking to slug it out for the Ablitt Cup.

"There's a few top sides out there who will give us a tough time, but I know our boys can't wait to go out there and prove they deserve to be in next season's team," South Africa captain Kyle Brown said at the SCC 7s press conference on Thursday.

Besides the Springboks, defending champions Borneo Eagles of Malaysia will also have to fend off competition from the development squads of France and England.

Hosts SCC have also boosted their ranks by including Japan's national sevens captain Jamie Henry as a guest player.
