Uncapped Ryan Bevington is one of eight Ospreys named in Warren Gatland's squad for the Wales V Barbarians fixture at the Millennium Stadium on Saturday 4th June.
Bevington, who was an unused member of the Six Nations squad earlier this year, is one five uncapped players in the squad along with Dragons pair Lloyd Burns (hooker) and Toby Faletau (flanker), and Scarlets duo Lou Reed (second row) and Scott Williams (centre).
Cardiff Blues back row Sam Warburton will captain the side in the absence of Scarlets hooker Matthew Rees, who is rested.
Three former Ospreys are also selected, Gavin Henson (Toulon), Dragons wing Aled Brew and Tavis Knoyle of the Scarlets.
The Baa-Baas side will feature the likes of Italian talisman Sergio Parisse, South African Rugby World Cup winners Francois Steyn and Ruan Pienaar and 98-times capped Welshman Martyn Williams.
Scarlets fly-half Stephen Jones is set to join Gareth Thomas as the most capped player in Welsh rugby history by making his 100th appearance against the Baa-baas.
"We have selected some exciting youngsters who have been chosen on form in the knowledge that there are a few players who are being rested or are injured for this game, but it means they have a chance to impress," said Gatland.
"It's a great opportunity for us to look at some players that have been hitting their form over the last few weeks.
"These are really exciting times for us as a squad, the Rugby World Cup is on the horizon and we begin our preparations with this first up match against the Barbarians before two intensive training camps in Poland and then our final three matches in August," said Gatland.
"Sam Warburton takes over the captaincy mantle from Matthew Rees, who is rested. Sam is one of the leaders in the squad and will benefit from the experience of captaining the side after having such an impressive Six Nations campaign."
