Fremantle’s watertight defence restricted Sydney to their lowest score since relocating to the Harbour City in 1982.
The Swans managed a paltry 2.7 (19) despite winning the inside 50 count 43-34 as Dockers duo Luke Ryan and Brennan Cox excelled in their defensive posts.
Kane Cornes believes Ryan, a mature-age recruit from VFL club Coburg, should be a "lock" in this year’s All-Australian side.
“What about the Dockers? I’m loving their form this year,” Cornes told AFL Media’s The Round So Far.
"Justin Longmuir knows what he’s doing, he’s clearly really structurally sound and tactically really switched on.
“The Dockers are having a terrific year, I didn’t expect them to be as competitive.
“Luke Ryan is an All-Australian so lock him in there, he was magnificent again tonight (Saturday night) with the amount of footy that he wins and how he uses it.”
Cox is out of contract at season’s end and Cornes wouldn’t be surprised to see Adelaide attempt to lure the South Australian home in the off-season.
“(Brennan) Cox as well, five contested marks tonight (Saturday),” Cornes said.
“Now you told me off-air Mitch (Cleary) that he’s out of contract, he’s a South Australian from Woodville West-Torrens.
“I’d be shocked if the Adelaide Football Club aren’t going to have a little bit of a sniff around for him because when Griffin Logue comes back and (Joel) Hamling comes back and (Alex) Pearce comes back, will he still hold his spot? So he may be looking for other opportunities.”
Cox, 22, has been a revelation in defence after beginning his career as a forward.
