OLD Scotch etched itself into football folklore by securing three consecutive NTFA Division 2 flags with a commanding 31-point victory over St Pats on Saturday.

It was the Thistles' fifth premiership in seven years, and they are the competition's first club to go back-to-back-to-back.

Old Scotch made a strong start in front of 2500 people at Youngtown Oval as St Pats looked rattled, with several indiscipline acts resulting in four 50-metre penalties, which yielded two gifted goals to the victors in the opening term.

Dan Ellis converted the first major as the Thistles' made the most of their many advances forward, while Shaun Smith kicked 3.1 to have the Saints on the back foot.

Ellis was potent in the midfield, and St Pats' first goal came at the 12-minute mark thanks to veteran Paul Kelly's rolling shot.

That's was all they could manage in the opening 30 minutes, and they trailed by 33 points.

St Pats could not move the ball in the inside-50 with any confidence or conviction, and they failed to improve throughout the match.

The game slowed down with minimal scoring chances for either side midway through the second quarter, However, Old Scotch's George Walker broke the duck with an outstanding long bomb from outside the 50-metre arch.

The margin was 32 points at half-time and the free kicks against continued to cost St Pats - handing the ball to Old Scotch within scoring range.

Walker booted two majors in the third stanza as Old Scotch continued to rule the state of play, while Chris Hay and Josh Bellchambers combined to kick consecutive goals for St Pats.

Shaun Muller immediately quashed any chance of a Saints comeback by converting his second major, leaving St Pats with a 52-point deficit to erase with one quarter to play.

The Saints failed to roll over, keeping the premiers to just one point in the final term as the runners-up scored 3.4 to add respectability to the scoreboard.

St Pats went through the home-and-away season undefeated, only to lose both the second semi-final and grand final to Old Scotch.

Thistles coach Kim Curtis said he was proud to achieve history and admired the way that his players had fought out season 2015.

"We had a slow start against them in the second semi-final and we made a point of not doing that again ... we wanted to see them chase us this time," he said.

"Our teamwork was impressive and the way we linked up with our handball and our run was great.

"We had a slow start (to the season) and a lot of teams wrote us off, but as a club and coaching panel we knew where we were going to be at the end of the year, and she came through.

"We lost over 30 players from last year's grand final, and to scrape through ... it's just fantastic.

"To win three in a row means a hell of a lot to the club."
