Dewi Lake and Alex Callender will captain the two sides in their respective uncapped fixtures, which see the men kick off at 2pm followed by the women at 5pm.

There are four uncapped players among the men’s replacements: loose-head prop Rhys Barratt, tight-head prop Ben Warren, second row Ryan Woodman and back row Harrison Keddie.

Second row Teddy Williams makes his return to the red jersey for the first time this season following injury.

There are five uncapped players in the women’s match-day squad. Wings Amy Williams and Kelsey Webster, prop Stella Orrin, flanker Lucy Isaac and scrum half Lily Hawkins are the new faces to wear the red of Wales for the first time at senior level.

Flanker Alisha Joyce makes her first start for Wales since the birth of her son Ralphie.

Eleven of the women’s starting line-up are aged 22 or under and 14 of them have played Celtic Challenge rugby for Brython Thunder or Gwalia Lightning.

Sean Lynn, Women's Head coach, said:

“This is a young and exciting team selected to face the Barbarians and every one of these players have deserved this opportunity.

“We have five new faces in Amy Williams, Kelsie Webster, Stella Orrin, Lucy Isaac and Lily Hawkins, and they are representing the future of this Wales team.

“We asked the players to assume nothing and to all fight for this chance to wear the red jersey, they have done that in training in the last three weeks and deserve to be selected."

Steve Tandy, Men's Head coach, said:

“I’m delighted for Rhys, Ben, Ryan and Harrison, who are all in-line to make their first senior appearance for Wales

“The Barbarians will present a good challenge for us. They have lots of skilful players and I’m sure it’ll be a high pace game with lots of offloads. That in turn will be a great preparation for us as we head into the Nations Championship and playing Fiji the week after.

“The more games we play the more consistent we can be. We’re looking to pick up where we left off in the Six Nations and continue to build and improve as a group.”
