The Southern Football League Senior Colts team were inspired by the dominance of the under 15 team and over ran Great Southern when it was their turn to play on Saturday at Morphett Vale Oval.
It was Great Southern first out of the blocks, kicking with the use of a slight breeze in the first term.
Goals to Sweetman, McDonald and Martin had Great Southern lead by 19 points at the first change as they held Southern to only one point.
In the second quarter it was all Southern, but incredibly out of 12 shots on goal, they could only muster one major. The rest were points and went in at halftime four points in front.
The score of 2-12 was not the return the Southern team would have liked at half time after the great work from the likes King, Hay, Barrett, Mitchell and Rogerson.
Great Southern did not score in the second term despite the herculean efforts of Sweetman.
In the third term it was Great Southern that had the opportunity to make Southern pay for their inaccuracy in front of goal.
Sweetman, Morris, Ker, Johnson, Miller and Kleinig were finding plenty of the ball.
A goal to Brunton lifted the Great Southern team, as they kicked 3-3 for the term to take in a lead of eight points at three quarter time.
Treloar found the sticks and Martin as well and the game was set up for a big last term.
Southern came out hard in the last term and if inaccuracy plagued them in the second it did not in the last, as their fast run and carry blitzed the Great Southern side.
Chances to kick goals were missed by Great Southern at crucial stages in the last term, as they kicked three points to Southern's 4-4 to go down by 17 points. A couple of chances did not even make the distance.
Flett was a danger anywhere near goal, as was Galliford and Southern turned on a great performance when it mattered to win the Whittlesea Shield.
Winner of the Terry Thompson medal and the South award for Great Southern was Wade Sweetman. Best for Southern was James Hay.
