Tomos Williams is hungry to keep hold of Wales' number nine jersey, following his first taste of international rugby during Saturday's narrow win over South Africa at Washington D.C.
Following an impressive campaign with his home region, the jet-heeled scrum half was a stand-out performer in his first outing for Warren Gatland's side, scoring a try and setting up the match-winning score for Ryan Elias.
The youngster will compete against Scarlets' Gareth Davies and Ospreys-bound, Aled Davies, for a place in the matchday squads for the upcoming Tests in Argentina, and Williams is relishing the opportunity to gain more experience on the international stage.
"You always want to keep hold of the shirt but there's a lot of competition so I will keep working hard," said Williams.
"It is always nice to get a try but the win was more important. I think it was a good performance overall.
"It's the first time Wales have ever beaten South Africa on foreign soil so we are pretty happy. The weather conditions made it a scrappy game.
"We had a good patch the second period of the first half where we played some good rugby and got on the scoreboard.
"I never played against Argentina at age grade level so I am looking forward to this opportunity.
"They have some really big boys and are very similar to South Africa. So it is going to be a tough challenge but one we are looking forward to."
