Fremantle has ignited its season with a dramatic win against an injury-hit West Coast, finding its turbo button and clicking forward of centre to win RAC Derby 56 by 41 points at Optus Stadium.

Inspired by Glendinning-Allan Medal winner Caleb Serong, the Dockers won 16.12 (108) to 9.13 (67), kicking their highest score since round 17 last season and leaving reigning premier Geelong as the only winless team after three rounds this season. 

The margin did not reflect the high drama at Optus Stadium, as the Eagles showed great resilience to hold on with one fit player on the bench after injuries to Luke Shuey (hamstring), Jeremy McGovern (hamstring), Liam Ryan (leg), Jamie Cripps (leg) and Alex Witherden (head knock).

The dam wall burst in the final quarter, however, as Fremantle piled on the last six goals of the game in a reward for the attacking game style they implemented in the most entertaining RAC Derby for years. 

Serong was exceptional in the midfield, finishing with 35 possessions (16 contested), eight clearances and a game-high 12 inside 50s to win his second Glendinning-Allan Medal.

Small forward Sam Switkowski was the shot of life the team needed in the centre with 21 disposals, an equal game-high 10 score involvements and two goals, giving Freo the speed they have missed.

Michael Walters booted a game-high four goals in his first full match of the season after returning as the substitute last week, while ruckmen Sean Darcy and Luke Jackson gave the team a dominant advantage in hit-outs (69-16).

The Eagles' ability to fight on under duress was admirable, particularly in the third quarter as they restricted Fremantle to one goal and cut the margin to eight points at the final change. 

They were best served by in-form midfielder Tim Kelly (33 disposals and five clearances), while Andrew Gaff (28 and four inside 50s) produced an improved performance as an accountable midfielder. 

Fremantle has put a focus on starting games fast and physical but failed to deliver in the opening two rounds. They were jumped briefly by the Eagles on Sunday but lifted to match them in the highest-scoring opening quarter in Derby history.

Oscar Allen was the star early, flying for marks and kicking three goals, including two from beyond 50m, while Shuey was the dangerman in the middle with three clearances and two goal assists from six disposals coming off the back of the centre square.

Both teams played a frantic style that was handball heavy, using their runners and looking for the corridor, with Michael Walters' second goal cutting the margin to one point at the first break.

Fremantle made their defining move in the second quarter, kicking four unanswered goals to open a 22-point half-time margin through the speed of runners like Michael Frederick, Switkowski and Walters, who all kicked goals.

The third term was a slog as the Eagles clung on with one fit player on the bench for much of the term, drawing on all their grit and determination to win the quarter by 14 points and keep the game alive.

It always felt unsustainable, however, and Freo put their foot to the floor in the last term in what should prove a confidence-boosting win that shows the team a path to its best football.

Variety is the key for Freo unicorn
Jackson had three different roles for the first three centre bounces on Sunday, setting the tone for his first RAC Derby as a Freo Docker. He started as a ground-level midfielder at the first centre bounce, moved forward for the second, and then contested the third as a ruckman. He moved between the three roles and was more involved in the game as a result, finishing with 12 disposals, seven tackles and two goals, igniting the team four minutes in with a snap across his body. A number of potential marks went to ground on Sunday, but his increased involvement with time in the midfield was a big step forward.
