Check out some of the highlights of the massive upset victory.
Greater Western Sydney survived thunder, lightning and a rare rain delay to pull off the greatest victory in its short history, stunning the Sydney Swans by 32 points at Spotless Stadium.
The Swans led at every change and held a 24-point advantage in the second term, but the Giants never stopped coming and finished full of running for their first victory against their great rival.
Lightning actually struck the ground late in the first quarter, leading officials to delay the second term by 25 minutes as the storm was assessed and debris was cleaned up.
The stunning weather managed to overshadow Lance Franklin’s debut, with the former Hawk managing just 1.1 in GWS’ 15.9 (99) to 9.13 (67) shock.
But the ultimate story was the improvement of the Giants, who demonstrated they are no longer the competition’s easybeats, having earned just three victories in two previous seasons.
