The Swans moved one win away from another grand final appearance with their second victory over Tigers in a week, 12.4 (76) to 7.9 (51) at Narrandera Sportsground.

Conlan was on fire with three goals in the opening quarter and he finished with 6.2 in a best-on-ground performance that helped move the Swans through to a second semi-final showdown with Coolamon next week.

Griffith got on top in the midfield early and with Conlan on song in attack, they were apply scoreboard pressure to Tigers. The Swans led by 11 points at quarter time and 15 points at the main break.

Josh Gaynor kicked the first two goals of the third quarter to put Tigers within three points and it looked as if the Wagga team were making their run.

But Griffith replied through Jack Rowston, Jono Gastin and Conlan to extend the margin to a game-high 20 points at three-quarter-time.

Any chance of a Tigers comeback was quickly slammed shut in the last quarter as Griffith piled on three goals in the opening six minutes to lead by 39 points.

Tigers kicked the final two goals of the game but the damage was done.

Griffith coach Will Griggs was rapt with the pressure his team brought, which forced Tigers into making a number of uncharacteristic errors.

"It was good. Another good four-quarter performance," Griggs said.

"I'm assuming it would have looked like a pretty good game out there. Once again our pressure was on. It's a big thing, when you put the pressure on, you don't give them much time to make the right choices by foot and I think we played a bit on their turnovers today and we rebounded pretty well, which is good."

Griggs was full of praise for Conlan's performance.

"Absolutely. I thought he could have got a few more free kicks down there too, in that first quarter anyway. He was dominating, he was kicking them from anywhere," he said.

"The second half, and third quarter especially, we were probably bombing it in a little too much but when they double team, or put two or three blokes on one of them, there's always a few blokes that are loose and we've just got to lower our eyes a bit and pick them out."

Aside from Conlan, Jack Rowston was brilliant in the midfield for Griffith and set the tone early with a lot of strong bollocking work in the middle.

Nathan Richards won the ruck battle, while Jordan Iudica, James Toscan and Oswald Herrmann gave the Swans plenty of drive from defence.

Griffith now take on Coolamon to be the first team through to the grand final. Griggs is happy with how the Swans are building.

"We got through unscathed too, so we're really happy and we get a few more back in next week as well so it's exciting times," he said.'

Wagga Tigers were well served by Ben Kelly and Lahn Shepherd, while Jake Mascini was the spark that helped get them going in the third term.

Kelly kept Griffith forward Jacob Conlan to one goal, while Shepherd ran with Griggs and worked tirelessly all day.
