DAN Biggar has labelled Saturday’s third test as a “great opportunity” for Wales to secure a momentous series win against the world champions.

The series is currently level after a late Josh Adams try was converted by Gareth Anscombe for a 13-12 win in Bloemfontein.

The Wales captain has overcome a shoulder injury that forced him to be replaced by Anscombe in the second test, and looking ahead to the decider in Cape Town, Biggar said the team would leave nothing out there come the final whistle on Saturday.

“It’s a great opportunity on Saturday for us to win a series here,” he said. “If we said that four or five weeks ago, you’d probably have been laughed out of town.

“I’m really looking forward to it. As a group we’ve put a huge amount into this tour in terms of the amount of training we’ve done and the amount of sacrifices we’ve made.

“We’ve worked our absolute socks off so it would be brilliant to get a full reward at the end of Saturday.

“We know this is our last week of the season so we can go out and give absolutely everything and leave it all out there and hopefully we can enjoy a really good break with some really positive memories of this trip.”

Wayne Pivac has made just one change for each test, with the side reverting to the one which started in Pretoria due to Alex Cuthbert's injury. In contrast, his opposite number Jacques Nienaber has made full use of his squad across the series.

But Biggar said he was confident the players still had enough in the tank to overcome the hosts.

“For us it’s about being disciplined and putting in an 80 minute performance,” he said.

“We’ve been really good in the first couple of tests. We haven’t given the Springboks too many cheap points.

“We’re hoping if we’re as clinical as we have been in the last couple of weeks then we’re going to be in with a shout.

“You’d imagine it will be very much the same [form the Springboks].

“It’s a credit to South Africa and how well drilled and coached [they are] and how well they do the basics.

“Our defensive review every time you play South Africa is very similar. You know exactly what’s coming, but it’s just whether you’re good enough or powerful enough to stop it on the day.”
