GWS Giants vs Sydney Swans Verdict


The Giants have been given a 9.5-point start in the Sydney derby and that appeals as the value bet for this Round 20 clash. Also take Aaron Cadman in the goal markets and Errol Gulden for disposals. 

  • GWS have won three of their past four matches at ENGIE Stadium and defeated the Swans by 44 points the last time the two sides met at the venue.
  • Aaron Cadman has kicked 10 goals from his past four matches against Sydney.
  • Errol Gulden is averaging over 30 disposals in his past seven matches against the Giants.
  • Sydney have lost three of their past four matches. 

Head to Head Stats


Sydney were 41-point winners in the Round 6 meeting at the SCG this season, but the Giants took out the last fixture at ENGIE Stadium by 44 points, with that match held in Round 20 last season. The Swans have won six of the past seven between the two sides.

GWS Giants Form


The Giants have been the Jekyll and Hyde side of the AFL this season, capable of beating the competition's best before producing costly losses against lower-ranked opposition. 

They famously knocked over Brisbane by 78 points in Round 11 and Fremantle by 21 points three weeks ago, but have also suffered disappointing defeats in games they were expected to win.

Last week was another example, going down to Essendon by three points after failing to capitalise on numerous opportunities. The Giants finished with 8.16, creating enough chances to win before poor conversion proved decisive. 

Jake Stringer endured a nightmare afternoon in front of goal, finishing with 0.7 after booting seven goals against Geelong the previous week.

Sydney Swans Form


Sydney enters Round 20 with a 13-5 record but is beginning to lose its grip on a top-four position after dropping three of its past four matches. 

Last week's 16-point loss to Adelaide was particularly concerning, handing the Swans their first defeat at the SCG this season.

Isaac Heeney (29 disposals) and Tom Papley (four goals) provided plenty of spark, but Sydney was beaten around the contest, losing both contested possessions and clearances. 

Charlie Curnow was held goalless after kicking 28 goals across his previous six matches, while Heeney has now registered 30 or more disposals in five of his past seven outings. 

Errol Gulden continues to accumulate consistently, recording 25+ disposals in two of his past three matches.

GWS Giants vs Sydney Swans Team News


GWS' Adam Kingsley has been forced into one change after captain Toby Greene was ruled out through injury. Harvey Thomas returns to the side, with the Giants hoping to bounce back in the Sydney Derby despite losing their inspirational skipper.

The Swans have made two changes, with Harry Kyle and Ben Cootee earning recalls. Harry Cunningham misses through injury, while Angus Sheldrick has been omitted as Sydney looks to continue its push towards the top four.

Verdict

Giants are backed to push the Swans with Cadman a threat up forward. Gulden to find plenty of freedom for Sydney.
