After a bright start at Blacktown on Saturday, the West Coast Eagles were overrun by an impressive Giants side in a 3.6 (24) to 6.8 (44) defeat, GWS recording their first win of the season in front of their home crowd.
The ever-prolific Alyce Parker (23 disposals, 10 clearances, 16 contested possessions) was reliably prominent for the hosts, supported by Nicola Barr and Rebecca Beeson.
But it was 18-year-old Zarlie Goldsworthy who stole the show with her class.
The emerging star kicked three goals in an electric performance.
The Eagles' own young gun Ella Roberts also shone, kickstarting the match with the opening goal.
Former Giant Aimee Schmidt backed up Roberts' goal with one of her own to build the margin to 12 points before quarter time, but it would be the last time the visitors would slot a major.
A skirmish erupted as tempers boiled in the second term and GWS debutant Rene Caris took advantage of a momentarily distracted West Coast to kick her first career goal.
Chloe Dalton put the Giants in front for the first time before a monster effort by the Eagles drew level 2.5 (17) by halftime.
There was no stopping the Giants in the second half, with GWS gathering four more contested possessions and 10 more uncontested disposals in comparison to West Coast's in the third term.
Three majors to Zarlie Goldsworthy and one from skipper Alicia Eva blew the margin out to 26 points, effectively ending the contest.
The Giants (1-5) have a chance to build a winning streak when they take on St Kilda next round, while West Coast (1-5) face an uphill battle against reigning premier Melbourne.
