What it means for Port Adelaide: The Power (8-9) need a big turnaround to keep themselves in the hunt for the finals. They've lost three of their past four games to sit one win and percentage outside of the eight.
What it means for Greater Western Sydney: The Giants (10-7) are in the mix for a top-four berth after their outstanding win against Collingwood. They'll be keen to get a win in Heath Shaw's 300th game.
The stat: In three games against the Power at Adelaide Oval, the Giants hold a 2-1 advantage. Overall, the Giants have won their past four games against the Power to take a 5-4 lead since they first met in 2012.
The match-up: Tom Clurey v Jeremy Cameron
Another big test for Clurey, the No.1 Power key defender in the Official AFL Player Ratings, and 204th overall. Cameron (the Giants' No.1 key forward, and 91st overall) is leading the Coleman Medal race with 54 goals for the season, and booted six against Collingwood last week.
It's a big week for: Heath Shaw
The dual All Australian will be up for a big performance to celebrate his 300th-game milestone. Has been an outstanding contributor to the Giants since joining the club from Collingwood.
Big call: The Giants boot the first four goals of the game to put the result beyond doubt early.
Prediction: Giants by 37 points
