Melbourne vs Carlton Prediction
Carlton are favourite and I’m not going to argue with…
St Kilda vs Sydney Prediction
Sydney sit second on the ladder but have won only two of their last five. They’re still favourites here, but the Saints getting 13.5 at Marvel is the value, and the points look like staying down.

Sydney Sit Second On The Ladder, But Two Wins In Five Says Otherwise. St Kilda Have The Class To Cover The Line At Marvel.
Sydney are the better side on paper and I have got them getting home on Saturday afternoon. But there is a gap between winning and winning by more than two goals, and that gap is where St Kilda’s line sits.
Back the Swans straight, then take the Saints on the handicap and the points under. All three cash if St Kilda’s recent form holds up better than Sydney’s ladder spot suggests it should.
St Kilda have the class to hang around
St Kilda at Marvel in front of their own crowd are better than a 13.5 point underdog. They do not give sides much room, and neither team has blown the other out. That is why the line is the play, even with Sydney the rightful favourite.
Sydney’s midfield wins the day
Sydney get first hands in the ruck and win the clearances, and that control of the middle is how they get over the top in a close one. It is enough to win. It is not enough to run away.
This one stays low scoring
St Kilda work the ball through the air and use it to slow the game to their own tempo. When they drag the pace down like that the scoreboard stays quiet, and that is the case for the under.
The crack in the cover
St Kilda without Max King lose some scoring punch, so if the Saints go quiet the margin can stretch past 13.5. I will wear that risk, but St Kilda have won three of their last five and I am backing that form to hold up at home.
St Kilda vs Sydney Tip
Sydney win it, but only just. I make it about eleven, so St Kilda pocket the 13.5 at home.

Michael’s Verdict
Sydney by a kick or two, St Kilda to cover the 13.5, and the under is the third leg. The one crack is King’s absence thinning the Saints up forward, but St Kilda’s recent form gives me the confidence to back it. Take the points.

Player Prop Predictions
Hayden McLean to kick a goal, $1.48. Found the goals in three of his last six and I’ve got the Swans on top, so the ball spends its time going his way.
Rowan Marshall to kick a goal, $1.41. He’s hit the scoreboard in three of his last six.
Chad Warner 25 or more disposals, $1.81. Racked up 32 last start, his biggest of the lot, and I’ve got Sydney winning the midfield battle. Over 25 is well within him.
Max Hall to kick a goal, $2.15. Goals in four of his last seven and the Saints keeping this tight at home means the majors get shared around. At $2.15 he’s worth the risk.
Mitch Owens to kick a goal, $1.40. Slotted two last start and he’s hit the scoreboard in four of seven. With St Kilda holding the margin at home he’ll get his chances.
