Fremantle has crushed West Coast in a brutal Derby, piling on 17 unanswered goals on the way to a record 101-point win at Optus Stadium.
Inspired by Glendinning-Allan medallist Lachie Schultz and young ruck star Luke Jackson, the Dockers took no mercy on their crosstown rivals, winning 20.14 (134) to 4.9 (33) in Derby 57.
The Eagles did not play with the level of intensity demanded and were punished in the contest and ultimately on the scoreboard.
Fremantle, meanwhile, produced the football that was expected of it this season, controlling stoppages, running forward in waves, and using the ball with precision as it handballed past its opponents.
Schultz won his second Glendinning-Allan Medal with a dynamic performance in attack, finishing with 24 disposals, seven inside 50s and a game-high five goals.
The Eagles kicked the first two goals of the game and dominated inside 50s (11-2) before Fremantle adjusted, lifting its physical approach, and enjoyed some dominance of its own with 13 of the next 14 forward entries.
And while the Eagles managed 2.2 from their dominance, the Dockers took full advantage of theirs and booted the next four goals of the quarter, with Matthew Johnson, Schultz and Sturt adding goals in 46 seconds of playing time.
Amiss added another when he was dumped in the goalsquare in a dangerous tackle by Tom Cole. Moments later, Alex Witherden won a free kick when he was slung by Michael Walters in a tackle that was also deemed dangerous by the umpire. Both Amiss and Witherden were both untroubled by the tackles and played on.
The Fremantle goal streak hit 14 before returning Eagle Jamaine Jones looked to have ended it when he poked one through from the goalsquare. It was overturned, however, due to a prior free kick. The Dockers continued their run thereafter to build a 95-point lead at the last change.
Wingman Andrew Gaff ended the run when he kicked West Coast's third goal at the start of the final term, providing brief respite for his team's defenders, who were under the pump the entire day.
