Catherine Zimmerman stunned Sydney FC with a goal in injury-time to earn Melbourne Victory a 2-2 draw with the A-League Women's title favourites.
Victory jumped off the canvas from 2-0 down on Wednesday night to salvage a draw at City Vista Recreation Centre.
Second-half goals to Princess Ibini and Remy Siemsen gave Sydney FC the edge - and the chance for grand final revenge - before Lia Privitelli reduced the deficit in the 68th minute for the clearly second-best Victory.
In the 92nd minute, the Sky Blues were made to pay for missed chances when Zimmerman pounced on a loose ball in the box to thrash home a left-footed volley.
The result is unlikely to change the finals equation though as Sydney FC are still on top and likely to stay there, while Victory are on track for a top-four finish.
But it sets up a delicious finals series given last year's grand final was won by Victory over their great rivals against the odds.
On the back of April's grand-final win and this comeback, Victory might claim a mental edge.
Sydney laid siege to Victory's goal without success in the first half and were on top of the contest without truly finding their groove.
Sydney fluffed their lines in front of goal before a moment of magic from Ibini.
The towering winger danced to the touchline and fired a left-footed shot from the tightest of angles after 50 minutes to break the deadlock.
Ten minutes later Siemsen was served up a fine chance from Charlize Rule's inviting centre, heading past Casey Dumont at close range.
With Victory veteran Amy Jackson forced off with a lower leg issue, Ante Juric's side looked set to blow out the margin.
Instead, substitute Privitelli popped up to tap home Courtney Nevin's firm cross when Natalie Tobin made a hash of her clearance.
That goal ended Sydney FC's record run without conceding in a 10-game streak dating back to November.
A dramatic finished looked in the off from that point.
Dumont, who had a top night in goal, produced a stunning save to deny Siemsen while Victory's Alex Chidiac also forced Jada Whyman into a rare piece of action.
Just when Sydney looked to have done enough, Zimmerman popped up to earn Victory a point.
The draw might have broken Sky Blue hearts but it leaves their quest for an unbeaten season - a feat achieved just twice in the league's history - on track and within sight.
Sydney face second-placed Melbourne City on Sunday in another top clash, while Victory host finals aspirants Perth Glory on Saturday.
