Seen as a danger game, Crystal Brook stamped its authority on the clash with the Roos after half-time and went on to win by a significant 57-point margin.
The Roosters were 21 points up at the long interval after kicking four goals against the breeze in the second term and edged further clear by three quarter time.
The final score was Crystal Brook 13.14 (92) to Orroroo 5.5 (35).
Crystal Brook skipper Luke Kapitola was outstanding back in the midfield while Ben Arbon was relishing his role in attack.
Scott Atkinson played his best game in the Roosters red and white colours, while Joel Millard and Cameron Arbon both played their roles in the victory.
While Atkinson finished his day’s work with a six goal bag, the ever dangerous wily veteran Luke Slattery helped himself to three majors.
Orroroo were well served by Jordan and Isaac Chapman, along with Tom Reid, and Andrew Catford
Impressive in defence, Roos full back Billie Tapscott kept the competition leading goal scorer Daniel Hill goal-less but they had five individual goal kickers in this game.
Roosters coach Shane Arbon said:
“Orroroo were good and really tested us last Saturday.
“They showed they are capable of taking it to most teams in this competition.
“We kicked 1.3 with the breeze of the first quarter and then held them out a bit against it in the second.
“To win like we did without a number of our key personnel was most pleasing.
“We had Matthew Gates, Shayne Biasci and Shaun Kapitola out, while Campbell Combe was away with the SA Country side in Perth.
“We unleashed our captain Luke Kapitola - who has been playing across half back for the last couple of rounds - and he produced his most dominant game over the last couple of years.
“Ben Arbon was excellent at centre half-forward and Joel Millard looked in ominous form across half-forward and on the ball.
“Scott Atkinson added to his five goals the previous week with a haul of six. Cameron Arbon was strong at fullback and Brad Eagle in the other key defensive post deserves to mention as well.”

Southern Flinders coach Scott Brand:

“Luke O'Connor (on ball/forward) is getting better each week he plays and Justin Thompson very good up forwards and on-ball.
“Tim (Woolford) did very good job on Jake Keller.”

“I felt we start to play better football in the second term into the breeze.
“With Jamestown having a lot of kids we took the game away from them after half-time and they couldn't match us in the second half.
“We used Maddy Hayes in more of a medium forward role after playing most of the year in the midfield so he could have a bit of a break.
“‘DP’ (Dylan Hewett) played at centre forward and after being away for a few weeks overseas just starting to get his fitness back.”
“Nick Hewitt one plenty of contested ball while Andrew Wilsons voice and leadership in defence is important component for us.
“Jared O'Donoghue on the wing was a strong contributor while Mason Armfield down back again produced as solid game as did Caden Harrison in ruck.
