British Lions and Wales hooker Matthew Rees, 29 has signed a new three-year contract, which will see him play with the Scarlets until 2013.
Ken Owens, 22, the rising front-row star and in-form Scarlets player this season has signed a new three-year contract.
Daniel Evans, 21, the talented, fast and athletic Scarlets fullback (former U15 British and Wales 80m hurdles champion) who earnt his first two senior Wales caps this summer in North America, signs on a new two-year deal with the region.
Lestyn Thomas, 33, the experienced prop with 33 Wales caps to his name and 158 Scarlets appearances since his debut in 2002 signs a new two-year contract with his region.
The quadruple signing sees the Scarlets secure some key experience and emerging international talent in the front and back lines of the squad as the region seeks to build and develop its team over the next two to three years.
The announcement will give Scarlets supporters an additional boost this week ahead of the region's big showdown against neighbouring rivals, The Ospreys, for the sell-out Magners League fixture at Parc y Scarlets on Boxing Day.
Announcing the new signings today at Parc y Scarlets, Chief Executive Paul Sergeant who was part of the team that secured the quartet of Scarlets players said:
"This is great news for our region as we secure four top players for the next two to three years. This group of signings exemplifies what the Scarlets are all about this season and going forward - a strong mix of emerging talent and experience.
"To retain the services, experience and strength of key senior players such as our British Lions hooker Matthew Rees and prop Iestyn Thomas is crucial in our bid to strengthen and develop our Scarlets squad going forward. With a big emphasis on bringing through talented Scarlets youth, it is important that our younger players have experienced senior players to learn from at crucial times."
Scarlets Head Coach Nigel Davies said: "I am delighted to see these four important players continue their great service of this region as part of the squad that we are building up here over the next three years.
"All four of these players are true Scarlets in terms of their passion for the region and commitment to the shirt - and I am particularly pleased that we have young guys like Ken and Dan continuing their commitment to us as we bring through and support emerging talent from within our region to play at the top levels of Welsh rugby.
"Ken and Dan are shining examples of the success of our region's academy and development system in identifying and bringing through talented young players onto the regional and international stage and we look forward to seeing their future careers with the Scarlets and we'd expect - the national squad, to continue pushing forward at a pace."
Matthew Rees joined the Scarlets in 2004 having played for the Celtic Warriors and Pontypridd. Wales' first choice hooker, with 34 caps for this country, Rees played a major role in the recent autumn internationals. He saw his profile on the world stage grow after three impressive performances with the British Lions over the summer as part of and all Welsh front row alongside Gethin Jenkins and Adam Jones. Rees has appeared 121 times for his region and enjoyed a successful 2006-2007 season with the Scarlets in which he made an impressive 25 appearances notching three tries; one of which came in the Heineken Cup semi-final against the Leicester Tigers.
Ken Owens joined the region in 2004 as part of the Scarlets Academy. He has since burst on to the scene in the 2009-10 season and has put in some notable performances within the Magners League and Heineken Cup that now put him in likely contention for a Wales jersey in the Six Nations next year. Owens started his rugby career at a young age with Carmarthen Athletic Under 8's and has been a shining example of the strength of the Scarlets development system.
Daniel Evans is one of Scarlets' emerging home-grown young talents who has quickly moved up the region's and Wales' age grade ranks to become a mainstay of the Scarlets regional squad. He is another product of the Scarlets academy system, starting out with Ammanford RFC, and later Llandybie and Tumble. Evans showed his speed and agility to be crowned Welsh & British 80m hurdles champion under 15. In May 2009, Evans was called up to the senior Wales squad for the summer tour of North America. Evans appeared in both tour matches and made his Wales debut in the 32-23 win over Canada (30 May 2009).
Iestyn Thomas, the experienced Wales prop, and one of the strongest scrummaging looseheads in Welsh game has been the cornerstone of the Scarlets pack for the past seven years. He joined from hometown club Pontypool and has an impressive line of rugby honours to his name which includes 33 caps for Wales after making his debut in this country's victory against Samoa in the Autumn of 2000. He also played in Wales' 2003 Rugby World Cup squad.
