Scarlets scrum-half Martin Roberts has won one Wales cap
The Scarlets have secured six of their squad on new contracts, including Wales scrum-half Martin Roberts.
Once-capped Roberts, 22, made his Test debut in the autumn against Canada and has signed a new three-year deal.
Other rising stars to commit to Parc y Scarlets are locks Dominic Day and Lou Reed, centre Jonathan Davies and back-row Johnathan Edwards.
Established prop Phil John, 27, completes the group after agreeing a two-year contract extension.
All six have seen regular first-team action this season in a Scarlets squad that has been hit hard by injuries.
Head coach Nigel Davies is delighted that the Scarlets' efforts at developing Welsh talent is bearing fruit.
"This is good news for the individual players, it shows our belief in them and is a positive move for the region as a whole," Davies said.
"Each of these players has had significant game-time with us in recent months and has grown in stature and influence.
"A number of them have had valuable experience as a result of our injury list and have responded positively to the high-pressure situations - showing great competitive spirit and ambition.
"We are keen to create a more sustainable look to our rugby operation and this is just the start.
"Developing young Welsh talent such as the likes of Jonathan Davies, Dominic Day, Lou Reed and others forms a fundamental part of the future success and sustainability of this region.
"The emergence of these players has been a real success story for us this season and we are pleased to be moving forward in this way by retaining and developing talented young players at key stages in their careers."
The Scarlets return to Magners League action on Sunday with a home match against Edinburgh.
Meanwhile, the Scarlets have been linked with a move for New Zealand flanker Daniel Braid, currently playing in Australia for Queensland Reds.
The Australian newspaper reports that Braid is considering exercising an opt-out clause in his contract at the end of the season.
"Both parties went into the arrangement with the full realisation that at the age of 28, Daniel was pretty keen to look at a long-term arrangement with a UK club," Reds contracting manager Ben Whitaker told The Australian.
"If he does find that, he'll go. If he doesn't, he'll stay. It's definitely not an awkward position."
