GWS is through to a semi final after breaking the St Kilda defence to win 15.11 (101) to 11.11 (77) at the MCG on Saturday afternoon.
The orange tsunami was in full force as the Giants attack, led by Toby Greene and Jesse Hogan, surpassed 100 points against the defensive-minded Saints.
Midfielder Josh Kelly was dominant kicking two goals, gathering 27 disposals, and picking up the pieces for onballer Stephen Coniglio who pulled out late.
St Kilda kicked the last three goals of the third quarter to stay alive, but weren't able to catch the surging Giants despite the late charge.
Ruckman Rowan Marshall was a standout for St Kilda, while Jake Steele (38 disposals) battled hard in the midfield.

Toby Greene-led GWS small forwards dominate
Guided by Giants skipper Greene, the GWS small attack was instrumental in a first-half blitz that left St Kilda trailing by 23 points.
Speedsters Brent Daniels and Toby Bedford, who recently escaped a one-match ban, gave the Saints defenders headaches with their creativity and run.
Bedford broke the game open in the third term, setting up a goal for forward target Jake Riccardi, before slotting his own moments later, courtesy of a Daniels assist.
The trio of small forwards combined for 23 score involvements and four goals, as GWS stormed into a semi final berth.

Tim Membrey, Stephen Coniglio left out late
Both sides were without key players, as GWS midfielder Coniglio and experienced Saints forward Tim Membrey were withdrawn ahead of the game.
Coniglio suffered an eye injury during Thursday training and was replaced by Xavier O'Halloran in the final side.
Anthony Caminiti came in for Membrey, who was taken out of St Kilda's side a few hours before the first bounce.
The Victorian side did not disclose condition of their experience forward, as the AFL okayed a late withdrawal.
"Membrey is currently receiving appropriate care and treatment due to a personal health matter," St Kilda said in a statement.
"Tim's health and wellbeing is our primary concern and the club asks that Tim and the Membrey family's privacy is respected at this time."

Ruck masterclass as Rowan Marshall, Kieran Briggs clash
It was a hotly contested battle between St Kilda's Rowan Marshall and Giant Kieran Briggs in the ruck, with the class of both players on full display.
Marshall collected 22 contested possessions, the most of any player on the ground, while shifting forward to kick a valuable goal for the Saints.
The hitouts count finished 28-18 in favour of Briggs, who also led his side with eight clearances for the match.
Since making his first appearance of the season in Round 10, Briggs has been an imposing force for GWS and has proved capable of matching the competition's best on the big stage.
