The 23-year-old is Oldham born-and-bred, and played his junior rugby at local outfit Saddleworth Rangers.
“It was hard news to take but I just missed out on making the final 17 last year,” he said.
“This is my first final for the senior squad and I’m ready to take my chance.
“It’s great to play for your hometown team, you always give that little bit extra because of that. There will be a few of us in the squad who have come through the ranks and are from the area which is good to see.
“Scott Naylor has been fantastic since he came here as coach. He sets up his game plans and gets us all working hard to follow those plans. It must be working, we’re in the final!”
Oldham face Hunslet Hawks in the final at Headingley, the fourth time this season that the two teams have met.
Nield is relishing the chance to savour the big occasion against the Hawks.
“All the lads are really looking forward to having a run out at Headingley on Sunday,” he added.
“Scott is playing it down though and doesn’t want us to get too ahead of ourselves.
“He has played for the top clubs and been involved in some of the biggest games so the advice he passes on to us is priceless.
“We’re expecting a big, physical game from Hunslet. We had the weekend off and training will be as normal this week to keep us focussed on the job ahead.”
