Farrell, 22, has been a stand-out performer in the competition in the opening 12 rounds, and has now scored 10 tries this season.
He told the club’s official website: “This is my first ever hat-trick in Super League so I am pleased with that, I think I may have got a hat-trick when I was a junior but it doesn’t happen very often, especially as a forward.
“I haven’t set myself a target or anything like that, I will just take the opportunities if they come my way. I take a bit of stick off the boys for that.
“The tries were just being at the right place at the right time but I will take them.”
