Subiaco held off a first-quarter comeback from Perth before wearing them down in a relentless final quarter to claim a 44-point victory at Sullivan Logistics Stadium on Saturday.
The scoreline of 16.4 (100) to 8.8 (56) continues a recent run of encouraging end-of-season performances for Beau Wardman's men, who have won two of their last three matches and maintained their lopsided dominance over Perth, having won 15 of 16 encounters.
