Where and when: Marvel Stadium, Saturday June 22, 4.35pm AEST

What it means for Brisbane: The young Lions haven't won outside Queensland since beating North Melbourne in round two at Marvel Stadium. Producing away from home is the sign of a really good team, and defeating a Saints side that has been resilient would be meritorious.

What it means for St Kilda: A percentage of 87 is wretched for a team eyeing off finals, so the Saints would need an extra win over the ninth-placed side to feature in September. They could tilt the equation in their favour, with a victory moving them to 7-6.

The stat: Brisbane is ranked No.2 for tackles inside 50 per game. Skipper Dayne Zorko leads the way with 27 through 12 games, while Charlie Cameron (17), Lincoln McCarthy (14), Mitch Robinson (14), Eric Hipwood (14) and Jarryd Lyons (12) have also helped apply pressure.

The match-up: Rowan Marshall v Stefan Martin

Marshall has been one of the Saints' best in 2019, having thrived after being thrust into the ruck role. Martin has been a bit down on form but despite being 32, there's life in the big man yet.
