Wales caretaker Head Coach Robin McBryde has praised his new young guns for their contributions to the Welsh victory over Canada by 32 points to 23 at the York Stadium in Toronto on Saturday.
He said all the youngsters proved they were worthy of their places and that they can challenge for international honours in the future.
Four new caps were awarded during the game with full back Daniel Evans and centre Jonathan Davies in the starting line-up and prop Craig Mitchell and centre Jonathan Spratt joining the fray as replacements.
Daniel Biggar won his second cap starting at number ten and delivered a performance which earned him Man of the Match recognition with a flawless goal kicking display.
McBryde said:"The youngsters all fronted up well with players like Dan Biggar showing he's got a long future at this level.
"Each of the new caps have also shown they belong in this environment so that is a very positive result for us.
"Daniel Evans, Jonathan Davies and Jonathan Spratt all showed up well during the game and Craig Mitchell almost scored a try when he came on which would have been a moment he would have remembered for the rest of his life.
"On reflection we'll take a win because we beat a Canadian team which ran us close last November when we had our full squad available.
"We know there's another level in us when we put it all together, but we have to be content with a hard fought win."
Neath and Ospreys prop Craig Mitchell said:"It was an incredible honour to win a cap for Wales and I will always cherish the experience of the day.
"My parents were in the crowd and when the anthem was being sung I felt very emotional at the honour it all represented for me..
"Being part of the squad has been an incredible learning experience and it has made me very determined to work hard to develop my game.
"The coaches and players have been tremendous and it is a superb environment to improve as a player.
"I am lucky to play for a club like Neath which has a proud history of providing international players for Wales and I am very grateful for the help they and the Ospreys have given me."
