Castleford second-rower Frankie Mariano has signed a new two-year deal.
Mariano, 27, is an ever-present for the Tigers this season, and is now committed until the end of 2016.
He said: “I feel really comfortable. I’ve never felt as comfortable as I do now in this team which is a big factor and it’s showing in my game.
“I wanted to play in every game, but it’s not something I expected with being in a brand new side and having to work my way in.
“Obviously I’ve done something right for Daryl Powell to keep playing me and this is exactly what I needed and wanted. Hopefully I can carry on, keep progressing and keep getting better.”
Coach Daryl Powell said: “It is great news for the club that Frankie has signed a new contract for the next two years.
“He has continued to improve throughout the year and has lots of room to develop his game even further.
“He is a big athlete with potential to play in three positions, which makes him a valuable member of our squad.”
