The GIANTS have ended their winless record against West Coast at Optus Stadium and continued the best start to a season in their history, strangling the Eagles for long periods to win by 65 points in a professional performance.
The undefeated GIANTS wanted to be ruthless in the west, and they were through the second and third quarters as they held West Coast goalless and went on an eight-goal run that broke the game open, eventually winning 16.12 (108) to 5.13 (43).
It was the club's first win against the Eagles at Optus Stadium from five matches and just their second ever against the Eagles in Perth, with the GIANTS' midfield avenging a shock loss in the same match-up 12 months ago.
A competitive final term from the Eagles that saw them kick three goals to five against the 3-0 GIANTS ensured the margin didn't blow out as had threatened through an error-riddled third quarter.
Tom Green (34 disposals and eight clearances), Stephen Coniglio (31 and six) and Josh Kelly (28 and seven inside 50s) were powerful in the middle and, with the help of dominant ruckman Kieran Briggs (34 hit-outs and 12 clearances), gave their team a 67-44 advantage in forward entries.
With star backman Sam Taylor racking up a massive 14 intercepts in defence, the GIANTS were also able to run in waves and punish the Eagles' turnovers, with No.1 Draft pick Aaron Cadman capitalising with a game-high three goals.
There was plenty of heat in the contest early as West Coast applied significant pressure to the GIANTS, held its own in the stoppage battle, and found a way to generate offence from its back half.
Harley Reid had the home crowd on its feet with his fearless, dashing style and ability to take on tacklers, while Tim Kelly showed his class with a running goal from 45m as the Eagles looked for opportunities to play fast and take the game on.
The GIANTS punish a turnover as well as anyone though, and once fundamental errors started creeping into the Eagles' game they pounced, kicking back-to-back red-time goals to put a 19-point gap in the game at the first break.
The second quarter descended into a slog. While the Eagles were able to get the ball in their forward half early, skill errors repeatedly let them down and the opportunities dried up as a result before the Giants landed three blows in six minutes late in the quarter.
By half-time they were 39 points clear and there were serious concerns for West Coast regarding the ruck dominance of GIANTS big man Briggs (23 hit-outs and six clearances to that point) against second-gamer Harry Barnett and ruck-forward Bailey Williams.
It was much of the same through the third as the GIANTS turned the screw and opened up a 10-goal lead, with West Coast at least showing some fight in the final term, particularly around the contest.
Half-back Jayden Hunt was impressive with his skill and ability to take the game on, while onballer Elliot Yeo battled manfully onball for 27 disposals and nine clearances.
Cleaning up fundamental errors will be a focus for the team, however, after much of the hard work in the midfield was undone forward of centre.
