There is genuine upset potential here.

St Kilda have covered the line in eight of the last nine meetings with Sydney and went extremely close to knocking them off at the SCG earlier this season.

The Swans have not been at their best either. They dropped games to Adelaide and Fremantle in recent weeks and have conceded 93 points a game across their last seven, which is a genuine concern for a supposed premiership contender.

The Saints are 7-3 at Marvel Stadium in 2026 and should regain Rowan Marshall, who was pulled out minutes before the bounce last week against North Melbourne with a back spasm.

Take the start with the Saints a big chance of getting the win.

St Kilda remain one of the better opponents in the competition for half-backs, and Nick Blakey had 26 disposals against them earlier in the year.

Brad Hill keeps filling the stat sheet and remains a good price for another 25+ touch game.

Darcy Wilson has passed 20 disposals in eight straight.

As long as we keep getting these prices for Hill then we simply have to keep backing the veteran.

Hill’s last five games read 34, 24, 39, 42 and 37 disposals, and the 24 came while he was tagged against Geelong.

Sydney have been the eighth best opponent for half-backs over the last five weeks.
