Captain Mick Ryan and coach Terry Fahey helped guide the side to an amazing 52-28 win over the Cowboys in one of the best grand finals seen in recent times.

It was a huge day for Ryan, who earlier in the day was the recipient of the Orana Credit Union referee's trophy for best and fairest player in the competition and after the match was also given the Bob Weir Medal for man of the match in the grand final.

A huge crowd estimated at more than 3500 packed Apex Oval to watch the two small clubs do battle and after 20 minutes, not many in the crowd would have taken 100-1 odds about Narromine winning.

Wellington scored four tries in the opening 18 minutes to lead

22-0 and it appeared as though they were headed for an easy afternoon in the sunshine which hit Apex Oval just before the start of the first grade contest.

Buoyed by a huge group of supporters on the eastern hill, the Cowboys were unstoppable as halfback Blaine Stanley constantly peppered the left-hand side of the Narromine defence.

But as is often the case in rugby league, the trend of the match soon changed when young fullback Chad Jacobson scored Narromine's first try in the 28th minute.

This sparked a flurry of points from the Jets, who scored three tries in the final stages of the half to trail 22-18 at the break.

The momentum shift continued in the second half as a shell-shocked Wellington continued to leak points.

Anthony 'Buddy' Louie opened the scoring in the second half with a quick dive from dummy-half and when centre Clint Walker crossed in the 46th minute, Narromine had escaped to an eight-point lead.

Arguably the turning point of the match came just three minutes later when Wellington winger Ed Daley, who had been good all day, dropped the ball when unmarked metres out from the line.

While the missed opportunity hurt them, the Cowboys were next to score when Rian Humphries crossed for his second try of the match but from there it was all Narromine as the Jets scored four tries in the final 15 minutes to score a brilliant 52-28 win.

Fahey was full of praise for his side after the game, saying he had a few anxious moments when the score was 22-0.

"I knew we could score some points, we just needed to get some ball," he said.

"But 22 points is a huge lead to give away, especially in a grand final against Wellington but we did it and we are going to celebrate."

Fahey praised Ryan and second-rower Rob Lake, saying that pair was the catalyst behind the great comeback.

"Mick Ryan was outstanding, he played out of his skin today, it was just a great effort," he said.

"He is a man of few words but his actions out there spoke today.

"And Rob Lake, the amount of work he got through was phenomenal."

While there was jubilation from the Jets, the mood was rather sombre in the Cowboys camp, with coach Billy Stanley admitting it just wasn't his side's day.

"We had a few bounces of the ball go against us and a few decisions as well but they were just too good," he said.

"I think we probably clocked off a little bit when we got to 22-0 and that came back to bite us but we will be back next year and hopefully we can go one better."
