Frio Frenzy. The Cats Lose Their Grip.

Perth Stadium turned electric on Friday night as Fremantle held off a fierce Geelong comeback to book their spot in the preliminary final. In front of 59,725 fans at Perth Stadium on Friday night, Fremantle skipped out to a 38-7 lead before Geelong hit the front in the third quarter on the back of three quick goals to Oliver Henry.

For a club that has waited a long time for this level of success, the early scare was almost too familiar. The Dockers finished the season as minor premiers with a club-record 19 wins, but that status came with baggage. The Dockers are the eighth minor premiers since 2000 to lose their qualifying final, and recovering from such a defeat hasn't been easy historically. After that qualifying final loss to Hawthorn, Fremantle came into Friday night needing to win to avoid the ignominy of a straight sets finals exit, a fate that would have ended their season a full month before the Grand Final.

Geelong made them sweat for it. Oliver Henry was the architect of the fight back, marking well and kicking his fourth goal to put the Cats in front 74-72, and for a moment it looked like Fremantle's finals campaign might unravel in front of its own fans. But the response came from the club's best player. The indomitable Luke Jackson produced a final for the ages with 25 disposals, 35 hitouts and two goals, dragging Fremantle back into the contest through the third quarter and setting up another for Patrick Voss to hand the lead back to the home side.

Geelong refused to go quietly. In a pressure-filled final term, Geelong cut a 24-point deficit back to eight points with 75 seconds remaining, and Perth Stadium held its breath. This is the kind of moment that's broken Fremantle before. The club's premiership drought stretches back to its 1994 formation, and in 32 years the Dockers have never lifted the cup. Long-suffering supporters have leaned on their own mythologies to survive the wait, chief among them Flagmantle and Wharfie Time, superstitions born from decades of near-misses and heartbreak.

On Friday night, Wharfie Time was real. Played for just the second time all season, the tradition sent the crowd into a frenzy as Voss kicked his fourth goal from the resulting centre clearance, sealing an 18.12, 120 to 16.10, 106 victory and snapping the finals tension in an instant.

It's worth pausing on how different that ending felt from the season series between these two sides. Back in round four, Geelong had won a stirring 10-point comeback of their own, storming home in the second half at GMHBA Stadium to beat Fremantle 16.14, 110 to 14.16, 100, after trailing by 35 points at half-time. Jackson was strong in that game too, with 27 disposals, 22 hitouts and 10 clearances, but it wasn't enough on the night. Friday's semi-final was almost a mirror image, except this time it was Fremantle riding the shock waves in the third term and holding on through Geelong's fightback rather than the other way round.

That history makes Friday's win feel less like a lucky escape and more like a side finally getting the finals result to match its regular-season form. Fremantle's healthiest list in the AFL and a club-record 19 wins had many pundits tipping a deep run before a ball was even kicked in September, but 18 of the past 25 minor premiers have gone on to reach the Grand Final, a stat that had started to look shaky after the Hawthorn loss. Friday night's win keeps Fremantle inside that pattern, and keeps the Flagmantle dream alive for another week.

Looking ahead, the reward for that win is a trip across the country. Fremantle will play in a preliminary final next week against the Sydney Swans, with the match set down for the Sydney Cricket Ground on Friday the 18th or Saturday the 19th of September, date still to be confirmed by the AFL. Sydney earned a home preliminary final by finishing on top of their side of the draw, meaning they'll come into the match with a week's rest behind them, while Fremantle has to back up from an absolute arm wrestle of a semi-final.

It's a daunting task on paper. The Dockers will need Jackson to back up his heroics and Voss to find that same magic in front of a hostile Sydney crowd, on the road, with no time to recover. But after coming through a final term like Friday's, in front of nearly 60,000 fans willing them home, nobody at Fremantle will be worried about the occasion. This is a group that has already shown it can find something extra when the game is slipping away.

Win, and Fremantle books a date at the MCG for the Grand Final on the 26th of September, one step from ending a wait that stretches back to the club's very first season. Lose, and the finals dream ends one game short of the big stage, for the second year running.

Either way, Friday night in Perth was the kind of finals football that reminds everyone why September footy hits differently. Wharfie Time doesn't get played often. When it does, it tends to be remembered.
