2005, Round three
West Coast 12.16 (88) d Fremantle 12.8 (80)
The first of Chris Judd's three consecutive Ross Glendinning Medals. The Brownlow medallist had 31 touches and kicked a goal but was overlooked for the three votes as the Eagles withstood a Josh Carr-inspired comeback.
2011, Round 18
West Coast 8.17 (65) d Fremantle 9.10 (64)
Leading by 22 points 18 minutes into the last term, the Eagles appeared home thanks to a Luke Shuey and Dean Cox masterclass. The Dockers then came with a flurry to produce a frantic final five minutes that saw the game rest on Hayden Ballantyne's boot.
2018, Round six
West Coast 13.11 (89) d Fremantle 12.9 (81)
The Eagles' twin towers delivered in attack, marking the first derby at Optus Stadium in style. But despite a dominant midfield performance from Andrew Gaff and Luke Shuey, the Glendinning-Allan Medal was split between the two sides.
