Greater Western Sydney have have consolidated their spot in the AFL's top four with a first-quarter onslaught to set up a 35-point victory over Melbourne.
The Giants outclassed the Demons, winning 14.13 (97) to 10.2 (62) in front of a sell-out crowd of 14,274 on Saturday afternoon at Manuka Oval.
It's a costly loss for Melbourne, who could drop out of the top eight by the end of the round, while GWS jump to second.
Giants coach Leon Cameron hailed his side's ability to pressure the opposition after they choked the Dees by laying on 119 tackles.
"Our tackle count probably explains it," Cameron said.
"Our contested ball in the first half was good, it dropped anyway in the second half - that was disappointing.
"But probably the damage had been done."
There were concerning signs for GWS early, with Melbourne booting the first three goals of the match.
But their momentum was arrested by two freakish goals, with Stephen Coniglio's left-foot banana from the boundary opening their account before Tom Scully benefited from a wicked off-break.
That sparked an avalanche, with GWS using a favourable breeze to pile on eight majors to give them their highest-scoring first quarter in the club's short history.
From there, the Dees struggled to break the Giants down and went into the main break trailing by six goals.
GWS kept Melbourne at arm's length in a dour second half, with any hopes of a comeback snuffed out by the Giants' strong defensive efforts.
The win's merit was boosted by the Giants being without star forwards Jonathon Patton (hamstring), Jeremy Cameron (hamstring) and Toby Greene (suspended).
Giants midfield star Josh Kelly played stints up forward and finished with three goals and 27 disposals, while veteran Steve Johnson and Devon Smith kicked two apiece.
Former Richmond star Brett Deledio celebrated his AFL comeback with a last-quarter goal in an otherwise quiet return.
Melbourne coach Simon Goodwin said a 20-minute patch in the first half and their inability to penetrate the Giants defence had cost them dearly.
"That was probably the difference in the game; the ability to be efficient going inside 50 and also the fact that they beat us around the clearances," Goodwin said.
To add to the Demons' pain, Jake Melksham could face a suspension for a high bump on Jacob Hopper.
Giants ruckman Shane Mumford will also come under scrutiny from the match review panel over two incidents.
He flung debutant Corey Maynard into the turf in a heavy tackle in the second quarter, before collecting Max Gawn with his shoulder in the third.
