Gold Coast has kept its slim finals chances alive and underlined its status as the season's best expansion team with a 25-point win against West Coast on Sunday.
The Suns, who have two wins and a draw from their past five games, jumped Geelong and Adelaide to sit one win outside the top three in Conference B with the grinding win.
They held their ground at stoppages and outclassed the Eagles when going forward, kicking 5.3 (33) to 1.2 (8) at an empty Mineral Resources Park in Perth.
The loss left West Coast anchored to the bottom of Conference B with one win from six games.
Gold Coast sharpshooter Kalinda Howarth was the star, booting four goals, including brilliant back-to-back snaps in the third quarter to separate the teams.
She kicked the opener and a goal on the siren, putting an exclamation point on her day out, which saw her constantly elude the Eagles' defenders.
The Suns' backline was also rock solid all day, keeping the Eagles to 0.2 across the first three quarters.
Eagles midfielder Hayley Bullas kicked her team's only goal when she won a free kick for a high tackle late in the final quarter, staying composed and converting her 30m set shot.
West Coast was bruised and battered by the final siren and looks to have lost Irish rookie Grace Kelly to a left leg injury after she left the game on a stretcher in the second quarter.
