Warren Gatland believes Wales are in a "really good space at the moment" after his experimental team shocked Argentina 23-10 in San Juan on Saturday.
The Dragons' triumph over the Pumas followed their 22-20 victory against South Africa in Washington last weekend..
The Six Nations Championship runners-up will complete their end-of-season travels in Santa Fe next weekend with another Test against Argentina.
The Wales coach, who made eight changes for the clash with the Pumas, said: "We feel like we are in a really good space at the moment. Welsh rugby is in a good place.
"We are really looking forward to the next 12 to 14 months before the World Cup.
"I thought it was a fantastic performance from the boys. We were under a bit of pressure in terms of territory and possession.
"But we spoke before the game about how important our defensive performance was going to be. The guys fronted up.
"That is what we asked of them and as a coaching team, you cannot ask for more than that, when the guys deliver for you and they put their bodies on the line.
"They gave everything so it was a really pleasing performance."
