The Ballarat Miners have swept the Geelong Supercats to win the Big V men's youth league one championship.

Players screamed with emotion when the full-time buzzer sounded at the Minerdome on Saturday.

The 21-point victory put the finishing touches on the three-game series which the Miners closed out in front of a sold-out crowd.

"It's a little bit surreal, the guys have locked in all season and to come back and do it back-to-back is just amazing," Miners head coach Daniel Knaggs said following the win.

Geelong looked up for the fight in the first quarter, but were trounced by the Miners with a bombardment of emotion-filled three point shots.

Taking a 15-point lead into the first break, the Miners increased the lead in the second quarter to lead by 20 at half-time. Dunmore, a former Ararat Redbacks player, said he felt the early lead helped settle the nerves.

"It's definitely the biggest thing I have even been part of," he said.

"We were confident going into the game and up for the challenge. Geelong are a good team and we had to come out all guns blazing and really lock down on their good players. I think we achieved that. As the game went on we built up our confidence once we got that early lead."

The writing was very much on the wall for Geelong early in the second-half, going down by as many as 27 points in the third.

Geelong fought back to its credit to come within 17 in the fourth, but it was too little, too late for the visitors who lost the game 110-89.

Dunmore's game wasn't one of the best with of the season and struggled to find accuracy around the basket.

"I think a little bit of my accuracy could be put down to nerves but mostly, it was just an off night," he said.

"We have confidence in each other and if someone is having an off night there are others who can step up and help fill the role."

The win provided an end to an almost perfect season for the Miners who sat atop the table most of the year.

A Big V men's youth league one championship will yield more than just bragging right for the Ballarat Miners.
