Regan Grace has signed a new two-and-a-half year contract with St Helens until the end of season 2019.
The 20-year-old has already scored five tries since making an impressive debut for the club on Good Friday at Wigan.
“I’m really happy to commit my future to the club for the next two-and-a-half years,” said Grace. “This season has been a good one for me so far – I have made my debut in a derby and have played in some big games.
“I’m now looking forward to working hard, improving and doing the best I can for the Saints.
“I’d like to thank everyone who has got me where I am today – from the people who spotted me when I was younger to the coaches at my amateur clubs.
“The staff have been brilliant since I joined the Saints – right from the Academy through to the first team – as has the club both on and off the field.
“The fans have also been superb and I would like to thank them for their support every time I pull on the Red Vee.”
The Welsh International joined the Saints after impressing on trial after playing rugby league for South Wales Scorpions at 16s and Wales at Under 18s.
His try scoring record in the u19s over the last two seasons was phenomenal and he was part of Derek Traynor’s unbeaten Academy Championship side in 2016.
Saints’ boss Justin Holbrook added: “”I have only been here a short time but I have seen the raw potential Regan has.
“He works hard in training and sets a strong example to the other younger players in the first team and Academy.
“He knows he isn’t the finished product and with a strong work ethic I am sure he will continue to improve at the club.”
