Only two late goals saved the Dockers from the third-lowest score in club history as the Saints emphatically ended their three-game losing streak on Friday night, 14.10 (94) to 5.3 (33).
The Saints won clearances by an astonishing 50-22. Caleb Serong only had 15 disposals - the lowest since his debut 2020 season - and fellow star Dockers onballer Andrew Brayshaw similarly was kept to 18 possessions.
Fremantle coach Justin Longmuir agreed the midfield numbers were "extraordinary"
By contrast, Saints midfielder Jack Macrae racked up 38 possessions and 14 clearances.
St Kilda forward Cooper Sharman kicked four goals, equalling his career-best haul, with three of them in the third term.
At three-quarter time, Sharman led Fremantle by 3.1 to 2.3, despite the game being played under the Marvel Stadium roof.
Fremantle's 1.1 was their third-lowest halftime score and their worst against the Saints.
After conceding more than 100 points in each of their previous three losses, the Saints were outstanding.
Ross Lyon coached his 200th win and it was a Lyon masterclass in terms of winning the contest and strangling the opposition.
He said they learned their lessons well from last week's loss to Brisbane, where Lyon had made his displeasure clear.
"Brisbane were great modelling on what you need to be as a clearance team," Lyon said.
"We went to school on that and just reminded our players ... there are some absolute fundamentals in that area of the ground that you need to deliver on.
"Everyone talks about getting your pressure up. We delivered on pressure tonight."
Longmuir and the Dockers, meanwhile, will spend an uncomfortable week under the blowtorch after a dismal performance.
"They did a good job to lock down Caleb and Andy ... we just couldn't get anything proactive going all night," Longmuir said.
"They were playing inside his (Serong's) jumper. They did that with Andy as well, shut those two down and then their key player in there got off the chain, in Macrae."
Once again, Fremantle struggled when challenged early.
"I'm concerned about our consistency, absolutely," Longmuir said.
"When we get challenged early in games ... I'm not sure we're up for the fight.
"You can't be that team. The main message after the game to the players is 'are we up for the challenge that an AFL season confronts us with'?'"
Longmuir was asked whether such a bad loss has him questioning himself.
"Everyone at the football club at the moment should be questioning themselves," he said.
"The first thing I look at after a performance like that - and any good leader should - is what did I get wrong? Of course I'm going to question myself."
Adding to a dirty night, Hayden Young suffered another hamstring injury.
"It looks serious ... it is concerning," Longmuir said.
Sharman's great game featured a miracle snapped goal over his shoulder in the third term.
He mimicked Brisbane great Jason Akermanis, putting one hand on his head and the other over his mouth after the freak goal.
After he felt coach Ross Lyon's wrath and was notably subbed out early in the second term of last week's loss to Brisbane, Saints youngster Hugo Garcia played out the game and kicked a final-quarter goal.
St Kilda suffered a pre-game blow when young gun Mattaes Phillipou was a late withdrawal.
Phillipou was included for his first game this season after recovering from a leg injury, but suffered a knock to his leg at Wednesday training and did not recover in time.
Saints defender Dougal Howard left the field in the first term complaining of groin soreness, but was able to return.
