Sunday's Group 10 Junior Rugby League under 11s league tag grand final victory for St Pat's was one wet and wild rollercoaster ride.

Saints completed a memorable 24-20 fightback win on their home turf at Jack Arrow Oval after a try in the second half of extra-time to player-of-the-match Jamie Powley.

Pat's were down by eight points at the last break but the girls in blue and white rallied in the rain.

Their coach Teejay Isbister was ecstatic with the way the team responded to the challenge in the last quarter.

"It was hard for a while there but the girls pulled it together to get the game into golden point. Taking the game to a second half of golden point is a good way to give yourself a heart attack but they did really well," he said.

"They played a good game in the wet weather. It's only the second time they've done that this year. Once they stuck to the short passes and ran the ball wide they killed it."

They sides traded early tries in torrential rain as they tried their hardest to get to grips with the weather.

Tilly Hancock pounced on a Mudgee kick with pace and scooted down the right wing to score, but the Dragons were able to respond in kind just minutes later.

At 8-all the match was anyone's for the taking but Mudgee were the team going into half-time with momentum - and they didn't let go of it when the match resumed.

A Saints error on the kick-off led to a Mudgee try on the very next play.

Mudgee continued to put pressure on St Pat's after strong runs from Emily McKid and Chloe Durrant took the team deep into Saints territory again.

Lily Gregory rewarded those efforts with a try to make it 16-8.

Pat's were lucky not to be down by more at three-quarter time after giving away the ball at their own play-the-ball and only just managing to tag a runaway Phoebe Forrester on the following set.

A converted try for the Saints at the start of the new quarter got them right back in the game but the margin went back out to six straight away when Mudgee ran the ball out of their own half and in for another try.

Hancock got the Saints close to responding but an error on the next play brought that opportunity to a halt.

Dragons' Emerson Colley almost put the game away for the visitors before she stepped out of bounds just a metre shy of the try line.

Hancock wasn't going to be denied on her next huge run down the field.

The Pat's number nine broke through the line and went the distance to get the game within two, before Skylah Hudson's high-pressure conversion took the game to golden try.

Both clubs came within inches of scoring in the first half of extra time but it was midway through the second period where the magic moment happened for St Pat's.

Powley had the ball close to half way and decided to turn on the afterburners and look for a gap down Mudgee's left wing.

It worked.

Powley put the ball down emphatically to deliver a memorable finals moment for the Saints.
