Yass Minor Rugby League president Mike Inkster said it was a massive achievement.

"To have four teams in the grand finals is a massive accomplishment for our little club and one that we are so very proud of," Inkster said.

The Division Two u11s side had a week off and play West Belconnen in the final while the other teams had to play in their preliminary elimination finals last weekend.

The u13s match went to extra time, then golden point in a nail-biter. There were field goal and long range penalty attempts, but the Magpies won the game through a Tony Davis try. They play South Tuggeranong in the final.

U13s coach Jason Howard said his side could go all the way.

"I believe in their ability to bring home the silverware to Walker Park this weekend," Howard said.

The Division Three u11s also fought hard, coming away with a 36-32 victory over the Queanbeyan Kangaroos. That sets up a final against Queanbeyan Blues.

Division Three u11s coach Paul Hewett said since numbers were down, the players had to put in extra yards.

"I couldn't be prouder of these little battlers," Hewett said.

"They often play with no reserves, but they all turn up with a smile on their faces."

The Division Two u11s side have been training hard in their week off as they prepare for their big occasion and their coach James Buser fancied their chances.

"They've been like little sponges," Buser said.

"They're eager to learn and improve their skills.

"I'm confident they can go all the way."

The u14s finished the year as minor premiers, but had a little scare in their 24-18 win against the Valley Dragons.

U14s captain Lane Davis said "hard work, discipline, the coaching staff and the parents' support" got them into the final against the Queanbeyan Blues and said their best asset was that they "all get along and are great mates that support and respect each other".

The two u11 sides play on Saturday while the u13 and u14 sides play on Sunday. All games are at Seiffert Oval.
