Roos fail to fire against Freo
North Melbourne suffers a 53-point loss at the hands of Fremantle on Sunday
The runaway 20.12 (132) to 12.7 (79) win was achieved without skipper Matthew Pavlich, who withdrew before the match with what coach Ross Lyon later said was a corked hamstring and general soreness.
Fremantle is now two games clear of ninth-placed St Kilda and 10th-ranked Carlton, with only one game to play.
The visitors dominated play in the opening quarter, crowding numbers around the ball and stifling the Kangaroos' run.

They led by 15 points at the first change, and from there held North Melbourne at arm's length, save for a three-goals-to-one burst early in the third quarter that saw Brad Scott's team briefly hit the front.
The game was still in the balance when the Kangaroos drew to within 10 points two minutes into the last quarter, but Fremantle then kicked clear with the next seven goals.
Classy midfielders Nat Fyfe and Stephen Hill were outstanding for the victors, as was ruckman Aaron Sandilands, who had 49 hit-outs and 15 disposals in just his second game back from injury.
Sandilands' opposite number Todd Goldstein could manage only eight hit-outs and two disposals.
Stand-in Fremantle captain Luke McPharlin convincingly beat North's star forward Drew Petrie, who wasn't helped by poor delivery forward.
Petrie started the day needing six goals to take the lead in the Coleman Medal race, but didn't manage one.
Tagger Ryan Crowley was also important, curbing veteran Brent Harvey's influence, and Clancee Pearce was prolific.
Small forwards Michael Walters and Hayden Ballantyne were the game's leading goalkickers, each booting four.
Kangaroos captain Andrew Swallow was his team's standout player, gathering 30 disposals and laying 13 tackles.
Defenders Scott McMahon and Scott Thompson also performed well, and Shaun Atley did his best to generate run from half-back.
Lindsay Thomas and Lachlan Hansen each booted three goals for the losers.
Coach Brad Scott said North Melbourne had expected a "finals-like atmosphere around the ball", but hadn't risen to the occasion.
"We just got completely outplayed," Scott said.
"You can talk about contrasting styles, but I said during the week that the fundamental of our game has, and will always be, the ability to win the ball in a contest, and we got convincingly beaten in that area today."
It was Fremantle's first win without Pavlich since round 22, 2008, snapping a run of six losses, and also the first time in its history it has beaten the Kangaroos at Etihad Stadium.
Souring the win was the loss of big man Kepler Bradley, who was subbed off at half-time after receiving a heavy knock to the head during the first quarter.
The sizeable final margin moved Fremantle (112.36 per cent) ahead of North Melbourne (111.58) on percentage, giving it the chance to earn a home final if it beats Melbourne next week and Geelong loses to the Sydney Swans.
