The Wales Under-21s are in action on Friday against Liechtenstein in Bangor, where Ash Baker will be aiming to play a part.
Friday’s contest is the first of two Euro 2019 qualifiers for the young Dragons, the second of which takes place next Tuesday against Portugal.
The call-up to the squad represents Baker’s first to the Under-21 set-up and caps a good period for the ex-Cardiff man, who has made three Owls appearances this season.
"I was in the physio room doing my recovery work and my phone went off from the Welsh FA," he said. "I had not had one before so I was quite surprised.
"I was capped once at Under-19s but that was it and I have not had any since. I'm a very proud Welshman so I was over the moon.
"Everyone wants to play for their country. As soon as I received the email, it was an honour to get a call-up.”
The 21-year-old made his full debut on the final day of the 2017/18 campaign during Wednesday’s 5-1 victory over Norwich at Hillsborough.
The Welshman has continued to show solid progression under manager Jos Luhukay and he added:
“Everything has happened so quick, it has been good to start two league games and a cup game this season.
"I'm just trying to take it in my stride."
