Cavaliers have ensured an all-Launceston decider with Northern Hawks for the first time in the State League's chequered 33-year history.
"No game goes exactly the way you want, but what happens is you stick to the structures and hope they get you halfway through," he said.
"The rest is up to the girls on the day when it comes down to those moments that are in between how they roll.
"The girls stepped up and delivered when it counted."
A sluggish Cavaliers were forced to catch up to Arrows late in the first term, but still held a decisive two-goal lead.
"We controlled the game, but that first quarter was pretty shaky," Roden said.
"When we came back and managed to get two or three goals in front late in the first, that gave us a real self-belief that if we were able to stay in front or stay close even, we were a really strong chance."
The two rivals traded goals after the break, but Cavaliers finished the stronger with five of the last seven scores.
Slowly but surely the best team for 19 rounds forged ahead after winning 11 of 12 third-term centre passes off the back of Shelby Miller, Dana Lester and Lucy Dennis.
Arrows did signal their intentions of one last fightback with four goals either side of the interval until Cavaliers regained ascendancy for an unassailable 12-goal buffer.
"That is not a great margin when you have a prolific scoring shooter like Sophie Gunn in the circle," he said.
"We knew we had to play that game right out. While we said the game was ours to lose, we just made sure we didn't go into our shells too."
