Their lead then extended to 38 points early in the third quarter after early second half goals to Nick Rodda and Matt Fowler.
East Fremantle did show signs of fighting back with the last two goals of the third term, but the Falcons steadied to start the last with Andrew Strijk goaling inside 30 seconds.
East Fremantle kept coming, though, with the game's next four goals to all of a sudden close to within eight points with only a couple of minutes remaining.

West Perth's back-line was outstanding led by Michael Pettigrew completely shutting down East Fremantle big man Rob Young and keeping him to just two disposals. Andrew Strijk (27 possessions), Luke Tedesco (21) and Dan Hunt (16) provided plenty of drive out of defence as well.
West Coast midfielder Bradd Dalziell was a tireless worker for East Fremantle for all four quarters finishing with 32 possessions, nine clearances and three goals.
