Wales' two-try hero Gavin Henson says he wants to be given the No 12 jersey for the rest of the autumn series.
"I need game time at centre, but feel it went well against the Springboks," said Henson, who plays at fly-half or full-back for the Ospreys.
"Early on I made a defensive mistake and they went through and scored, but I didn't let it get to me.
"It would be great to play all the internationals at 12, my partnership with Stephen Jones will get better."
Henson said the camp was gutted at not taking their chances to beat Tri-Nations champions South Africa.
"It was great to score my first tries in a proper Test match, but it's disappointing that we didn't win," Henson told BBC Sport Wales.
"Going into the game we really thought we could get a victory and as it panned out we should have.
"When it got to 23-22, we felt that if we could just edge in front we would hold it, but they showed why they are Tri Nations champions.
"Hopefully now we'll get a full house against New Zealand, but Romania are first - they beat Italy recently and will be tough, so we're not looking past that."
Fly-half Jones, who combined well with Henson in midfield, was equally devastated at the Springbok defeat.
"We could have turned the screw at 23-22, but it was disappointing when we worked so hard for our points then gave them easy scores," said Jones.
"We got the momentum and the crowd and were very confident in our play, but little things went wrong and cost us dearly.
"They were clinical every time we made an error.
"There is a lot of ability in our squad, though, and we will back ourselves against any nation in the world.
"We just need to get the ball in our hands and play with width."
