Wales coach Warren Gatland admitted to feeling "a bit of relief" after his team made hard work of beating South Africa in Cardiff.
Gatland's men led by 18 points just before half-time, but needed a Leigh Halfpenny penalty 12 minutes from time to secure a 24-22 victory and third successive home win against the Springboks.
"I suppose there is a bit of relief," Gatland said. "We started so well and looked comfortable, then the five minutes before half- time and five minutes after half-time weren't the best periods of the game for us.
"It was pretty nail-biting, but that is what Test match rugby is all about, and we came out on the right side of it."
