The number 13 might be unlucky for some, but Fremantle see it as magical as they try to snare a rare AFL finals berth.
Despite boasting a 10-7 win-loss record, the Dockers sit percentage adrift of the eighth-placed Kangaroos and will likely need at least three more wins to secure a top-eight spot.
Fremantle face tough games against high-flyers West Coast and Adelaide (away) over the next fortnight, before rounding out their season with matches against Richmond (home), North Melbourne (away) and Melbourne (home).
A four-match winning streak has fuelled belief within the Dockers' camp that they are capable of reaching the finals for just the fourth time in their history.
But Fremantle are yet to prove themselves against the best teams in the competition, with their round-one victory over Geelong being their only triumph against a side currently inside the top eight.
Coach Ross Lyon said his team needed to claim another big scalp to prove they were a worthy finals contender.
"We've beaten everyone below us and around us really - made a pretty good fist of that," Lyon said on Wednesday.
"And earlier in the year, we were able to knock off Geelong and St Kilda. Clearly, the Eagles are up near the top of the ladder.
"To earn the right to play finals, you've got to beat some good teams and that's the challenge that lays in front of us.
"The basic maths are 13 (wins) will get you in (to the finals). It's a big challenge in front of us, but it's good to have control of your own destiny with performance.
"The Eagles are clearly in the finals and are trying to secure top four. We're fighting for a top-eight berth and the only way to do that is to keep winning."
