Regan Grace has signed a contract extension with St Helens until the end of the 2021 season.
The Wales international joined the club after playing rugby league for South Wales Scorpions at Under-16s level and Wales Under-18s.
Grace made his first-team debut against Wigan Warriors in the Good Friday derby back in 2017 and he scored 18 tries in 33 appearances last season.
On his new deal, Grace said: “I’m delighted to have signed a new contract.
“I would like to thank Mike Rush, Eamonn McManus and head coach Justin Holbrook and all of the coaching staff who have helped me get to this point since my debut back in 2017.
“I am still young and have lots of learning to do, but I’m excited for what the future holds.”
Saints coach Justin Holbrook added: “It’s exciting news for the club to have Regan committing his future here.
“He is a young player who listens and is good to coach. He has learnt a lot in the last couple of years and although he still has a lot more to learn, he is such an explosive, natural runner, who is great to watch.
“He is an exciting young player to have on the end of our back line plays and I am confident he will achieve great things in a Saints shirt.”
