Fremantle are going the extra mile in their preparation for games this year.

Beyond the tactics, structures and game plans drilled into them — just as at any AFL club — the Dockers are even familiarising themselves with the names and faces of the umpires officiating their games.

Spotted on their wall near the door to exit their changerooms before Saturday night’s clash with North Melbourne was pictures and names of the four on-field umpires for the game.

It was a unique detail that caught Nick Riewoldt’s attention on The Agenda Setters.

“I saw this from the weekend, found it interesting,” he said, as vision of the pictures was shown.

“They’re clearly trying to arm the players with the umpires’ names.

“They look like mug shots, those pics.

“But I reckon the players have got enough to worry about, don’t they? Without trying to memorise umpires’ names.”

Craig Hutchison lauded the idea: “I think it’s smart — trying to get an edge.”

Whether it worked or not is up for debate, but they did win the free kick count, 25-23, in a thrilling six-point win.

Luke Jackson and Josh Treacy were the main protagonists for the Dockers, rescuing their side after major late scare.

The Dockers looked like they had Saturday night’s game in the bag after opening up a 28-point lead late in the third quarter.

But Jack Darling’s goal on the three-quarter time siren sparked a run of five straight goals for the Kangaroos, before a Paul Curtis behind with only seven minutes remaining levelled the scores.

Jackson popped up for what proved to be the match-winning goal when he latched on to a desperate handball from Jye Amiss and snapped truly in traffic with three minutes to go en route to the 10.13 (73) to 10.7 (67) victory.

“I thought Jye’s ground ball to get it out to Jacko was just as impressive as Jacko’s effort to finish it,” Fremantle coach Justin Longmuir said.

Then with North Melbourne pushing to level the scores in the final minute, Treacy took a huge mark in defence when there were three Kangaroos players around him.

“It was unbelievable,” Longmuir said.

“The last line of defence to be able to have the sticky fingers like that to mark it was handy“I would have rather him not kick it out of bounds on the full (after that), but you take the good with a bad maybe.”

Although Treacy didn’t kick a goal, he ended the match with six contested marks to his name.

It was Fremantle’s fourth victory on the trot, and improved their record to 8-5 ahead of home games against Essendon and St Kilda.

Fremantle goalsneak Sam Switkowski could be set for a stint on the sidelines after succumbing to hamstring tightness in the second half.

Dockers forward Patrick Voss was critical in the victory with three first-half goals, while Harry Sheezel was big for North Melbourne with 32 disposals and a goal.
