South Africa coach Rassie Erasmus described debutant Herschel Jantjies as “awesome” after the 23-year-old scrum-half scored two tries in a 35-17 triumph over Australia in their opening Rugby Championship clash on Saturday.

Jantjies put the hosts ahead after just seven minutes at Johannesburg’s Ellis Park before Lood De Jager extended the Springboks’ advantage.

Dane Haylett-Petty gave Australia hope with his side’s opening try of the evening to leave them trailing 14-10 at the interval.

But South Africa dominated after the break. Sibusiso Nkosi got his name on the scoresheet with 55 minutes gone.

Jantjies then went over for a second time before substitute Cobus Reinach sealed a convincing bonus-point victory in the closing seconds for the Springboks.

Jantjies’ highlight was a brilliant 62nd-minute try as he stole away down the blindside that gave the home team a decisive 28-10 lead.

“Herschel showed that he is definitely comfortable at this level and one can have nothing other than praise for him,” said Erasmus of the Stormers half-back, who has just one season of Super Rugby behind him.

“To come straight from Super Rugby and play like that – his service, his box-kicks, his technique, his grit on defence and of course his marvellous attacking ability – were awesome.

“It was a great start to his Springbok career,” added Erasmus of the official man of the match.

The Springboks ran in five tries to two as they pulled away in the second half, turning a tight 14-10 half-time lead into something approaching a rout for a perfect boost ahead of meeting the world champion All Blacks next weekend.

But while Erasmus was delighted with the result, and some of the individual showings, as he fielded an experimental XV as part of his World Cup planning, he said there would be more to come from his team.

“The performance itself wasn’t close to world-class, it was more about individuals who put their hands up and showed that they can prosper at international level,” he said.

“But we expected that because the team hasn’t played for a while. Rust was obviously one of our worries and whether the combinations would gel, but it came on through the game, even though it was stop-start.

“It was a bit frustrating but individuals showed some great form. But next week in New Zealand we’ll be fresh, the bulk of the team have flown over already and are used to the time zone and acclimatised.

“Plus some guys tonight have really put their hands up. Our last three games against the All Blacks have all been decided by a couple of points, so we are expecting a massive game.”
