GWS vs. Sydney Predictions

—

Best Bet

Sydney +9.5 @ $1.90

Bet Now

The Swans are 3-0 in their last three games against the Giants, including an 87-73 win at home in May. That was a good effort, and we have been impressed by their recent form with three consecutive wins over North Melbourne, St Kilda, and Fremantle.

GWS has also been playing well with a winning run, but with Sydney on the outside looking in, we think it plays better as the more desperate team. Last year’s finalists are leaving their run late, but a statement could be made against the Giants on Friday night.

Getting $2.42 for the Swans to win outright is a fair price, but getting a +9.5 start is good value. It should be a close game throughout, so take the underdogs to cover the spread.

Same Game Multi

Sydney +9.5, Isaac Heeney 2+ Goals, Aaron Cadman 2+ Goals, Total Match Points Over 168.5 @ $8.50

Bet Now

Punters get value odds for Isaac Heeney to score 2+ goals. He’s a $2 chance despite scoring five goals last week, and we expect that form to continue against GWS. We also expect those odds to firm throughout the week, so include him in AFL SGM picks.

Aaron Cadman is typically a safe bet to score 2+ goals, despite scoring just one last week. He had 16 goals in his previous four games prior to that, so we’re happy to stick with the Giants player who should have a big game.

Over 168.5 goes into the mix based on their recent meetings. It should be an open scoring contest, which could end with a 90-85 scoreline.

Best Value Bet

Sydney 1-39 @ $2.90

Bet Now

We have Sydney to win the game outright, so it’s worth taking the better odds for a 1-39 win.

Punters get $2.90 instead of $2.42 with outright betting markets, and we can’t see Sydney winning by 40+ points, so it’s a relatively safe betting option.

An upset is on the cards at ENGIE Stadium, so lock up the value.
