Following the contract renewals of Jarrod Evans, Josh Navidi, Willis Halaholo and Kristian Dacey, the highly-rated scrum-half has followed suit and will remain at the Arms Park. The 24-year-old has won seven caps for Wales while he has made 81 appearances for the Blues.
“I’m really happy to sign a new deal at the Blues,” he said.
“This is my home region and I am really happy here. We have a good squad, with a lot of young, exciting players that I have come through the ranks with and are now very good friends.
“We play a good brand of attacking rugby, which suits my own game and I am looking forward to continuing to improve both as an individual player and collectively as a team. Now I am just looking forward to some massive games in the remainder of our season and hopefully helping the Blues reach the PRO14 play-offs.”
Williams made his international debut last summer and was part of Wales’ Six Nations winning squad, starting and scoring a crucial try in the opening victory over France. And head coach John Mulvihill believes Williams has a massive future in the game both at regional and international level.
“Tomos is another local, exciting player to come through our pathway and is the best attacking scrum-half in Wales,” said Mulvihill. “He’s incredibly competitive and an important attacking and defensive spark for us. He has produced big moments in big games.
“He continually strives to be better, working on his all-round game and will be really important to our future success. He wants to be the number one scrum-half not just at Cardiff Blues but Wales, and that hunger and competitiveness is a great asset.
“The competition between Tomos, Lloyd Williams and Lewis Jones is really positive and brings the best out of all three players.”
