The Dockers have kept West Coast to their lowest score in Western derby history recording a commanding 55-point win.
It's back to back Derby wins for the Dockers who have now started the season with two wins and a loss following the 15.12.102 to 7.5.47.
The previous worst score from the Eagles in a derby was 7.6.48 back in round 19, 2012.
Fremantle increased their lead at each break from eight points to 34 points at the main break to 38 points at three quarter time.
The Eagles booted two goals in 30 seconds to start the second half to give early indication of a fight back but that sniff petered out quickly.
Darcy Tucker left the ground shortly after suffering concussion following a head knock while Alex Pearce left the field with a stinger on the knee but returned to the field a short time later.
Dockers stand-in coach Jaymie Graham said post-game it was a bit scary at the time.
"We were quite concerned but he's down in the rooms and he's bubbly, we'll have to investigate further but he's healthy and that's the main thing."
Graham said the coaching group was pleased with the mindset following some poor second half performances.
"We were really proud of the boys' performance. We thought it was quite a mature performance. West Coast came out hard but our boys stuck at it and put in a four quarter performance."
Lachie Schultz was awarded the Glendinning Allen Medal collecting 23-disposals, eight marks, kicking two goals and executing three tackles.
Matt Taberner booted three goals in his return while Rory Lobb and Michael Fredrick both kicked two majors.
Josh Kennedy was the only multiple goal scorer for the Eagles.
