Hardcastle said: “I want to take this new opportunity to continue my progression in rugby league, to find the best version of myself by reaching my full potential ahead of the World Cup.

“I believe I can achieve this at St Helens and I’m looking forward to this new chapter.

“My mums always says it’s not where you start it’s where you finish.”

Saints women’s coach Derek Hardman said: “I am delighted Amy has decided to join us ahead of the new campaign.

“She has years of experience having played in two World Cups and that can only benefit our group moving forward.

“We welcome her with open arms and we are excited to work with her when the season gets going.”
