Fremantle senior coach Justin Longmuir said ruckman Luke Jackson’s game was nothing short of outstanding in the win over Geelong in the Semi Final.

Speaking to the media post-game, Longmuir said Jackson’s 25 disposals, 35 hitouts and two goals amounted to a borderline untaggable performance.

“I thought he played a really strong game,” Longmuir said.

“He got ascendancy in the ruck.

"Teams can have any type of plans they have in place for negating rucks around the ground, but when someone competes as hard as he does in the ruck and then follows up the way he does, you can't tag that type of player.

"We put them under a bit of field position pressure, and he's up against a young ruck who's playing in a pretty hostile environment, and he was able to put him under a lot of pressure and draw a couple of free kicks.

"It's one thing to get the free kicks, but it's another thing to be able to settle and finish.”

Talking on Jackson’s strengths and big-game appetite, Longmuir said he's the ultimate competitor, helping his side gain ascendancy at clearance, winning the battle 44-31, including 23-13 centre clearances for the game.

“He’s an outstanding set shot and has great composure to be able to finish,” Longmuir said.

“He's a competitor. He wants to be around the ball, he wants to make a difference in the game.

"Sometimes you've got to temper that with those top players. But when your rucks are that competitive and they want to be part of the game and they want to influence the game, I imagine it's great being a midfielder under someone like that.”

Fremantle’s win sends the Club into a preliminary final for the first time since 2015, booking a ticket to face Sydney at the SCG.
