Phil Davies says Roberts is a Wales star of the future

Llanelli Scarlets have signed ex-Wales Under-21 scrum-half Martin Roberts from west Wales rivals the Ospreys.

"Martin has a great passing game, he will add depth in this position," said Scarlets director of rugby Phil Davies. "We believe he is a future Welsh star."

Roberts, 22, has made 20 appearances for the Ospreys since making his debut against Bath in October 2005.

His signing follows ex-All Black lock Simon Maling, Tonga scrum-half Sililo Martens and Bristol centre Rob Higgitt.

Roberts has played for Neath, Swansea and Bridgend, and been capped by Wales at Schools, Under-16, Under-19 and Under-21 levels.

He will contest the number nine jersey at the Scarlets with Martens and Liam Davies, Wales and Lions star Dwayne Peel moving to Sale in the summer.
