The Blitzboks finished 6th overall, but a number of surprising results saw them extend their lead overall with only tournaments in Paris and London left to play.

South Africa started the Singapore tournament 23 points ahead of Fiji in second place and now lead them by 25 points, courtesy of a crucial win over the Olympic champions in the 5th place semifinal. England, who finished third, moved closer to Fiji, but is still 27 points adrift of the Blitzboks.

"Yes, that win over Fiji was a vital one and one of the success stories of this tournament for us. By beating them in that crucial match, we could actually extend our lead over them, which is a massive bonus for us," Powell explained.

"We could also blood a number of youngsters, giving them proper game time and there does not seem to be any real injury concerns. Those are all positives."

Powell was not too happy with their Sunday performance though, which saw them lose to Australia 19-17 in the Cup quarter-final, before beating Fiji 19-14 in the 5th place semifinal. They were edged by New Zealand for 5th spot though, losing 17-12.

Canada won their first ever title in the series by beating USA 26-19 in the final.

Powell was not surprised by it.

"A lot of teams seem to battle to pick up their performances after Hong Kong. We also saw it last year when Kenya won their first ever title here and this time it happened to Canada. It is a tough tournament to play and we did not perform the way we wanted. We did extend our series lead though and that could prove pretty important."

The team arrives back Tuesday morning and Powell admits that some hard work awaits the squad before the last two tournaments in Paris (13/14 May) and London (20/21 May).

South Africa will play in pool A alongside Canada, Scotland and Japan.

"We have some work to do that is for sure. We made too many mistakes in certain areas, but there is nothing hard work cannot fix, said Powell.
