And after winning the backing of head coach Warren Gatland both before and after the 27-13 win over the Scots, the 24-year-old can't wait to have another run in the Test arena.
"I always thought Sam was going to make it, but once they told me on Saturday I was going to play I was so excited. I called my girlfriend and texted my parents," said Shingler.
"They were all at the game and I got a 'well done' message from my younger brother Steve after the game. When we used to watch the rugby as a family back in the day my mother (born in Dumfries) always supported Scotland, but I think we've turned her around now.
"The pace on the game is something I've never experience before, but the only real change for me from my normal position was having to get to the first ruck after the scrums. But it was something I really enjoyed.
"It was great actually playing for Wales and certainly vindicated my decision to concentrate on rugby over cricket. I was with Glamorgan for a few years and used to play rugby for fun in the winter break.
"But when I was released in 2007 I took rugby more seriously. It went well and her I am today."
Now Shingler is setting his sights on staying in and around the Welsh match-day 22 for the Triple Crown clash with England at Twickenham in two weeks time. He knows that will be difficult if, as expected, Warburton recovers from his dead leg in time to lead the side.
"Sam I a great player and he I also captain of the team. I don't think I will take his place, but maybe there will be a place for me somewhere else in the squad," said Shingler.
"On the back of what this team did at the Rugby World Cup it is every rugby player in Wales' dream to be a part of this set-up."
