Next up for Lake and his men is a Saturday assignment against the reigning world champions France in what will be another revenge mission. The 30-25 triumph over the young Pumas made up for the defeat to them a year ago, while the French beat Wales 32-10 in the Six Nations.
“It is a happy moment for us, and I’m very proud of the performance, but it is only one of five games,” warned Lake after the victory at the Racecourse ground in Rosario.
“We knew the game wasn’t going to be won in 20, 40 or even 60 minutes – we were in it for the long haul. Credit to Argentina, they drove us to the end.
“But we pride ourselves on our defence, just like the senior Welsh side, and it has come a long way in the five weeks we’ve been together. We dug in there till the end.”
There were 20 points from the boot of Cai Evans to guide Wales to an impressive victory and there were tries from Ospreys scrum half Harri Morgan at his second World Championships and another for Scarlets wing Ryan Conbeer at his third
“It was a very good game and getting the first win is very important. We’ve still got four games left, but this was a big win for us,” said Conbeer,
“When I went in to scrum half for my try everyone was worried. But I saw a gap, backed myself and went straight through.
“Going in ahead at half time was big for us. We said the game wouldn’t be won by then and we stepped up in the last 20 minutes.”
Morgan started and finished his first-half effort after receiving the ball from the back of a tricky scrum by outstanding No 8 Jac Morgan. His chip found Ro Dyer, who then passed back inside to his scrum half, who finished with aplomb as he side stepped past the last defender.
“It isn’t easy to play Argentina on their own patch and it’s a massive win for us. We dug in deep in the end and now we need to kick on from this and move on to France this weekend,” said Morgan.
