Two Melbourne Victory goals in the last 20 minutes, including a dramatic long range effort by Melina Ayres, were enough to cancel out Melbourne City's 63rd minute and give the navy blues an upset triumph in the second Melbourne derby of the W-League season.
The result - not something most pundits predicted - means that City remain in the top four, but, following Canberra's win over Western Sydney, the Sky Blues are only now a point clear of the fifth placed club from the ACT.
They will have to improve results and performances in the final few games of the campaign if they are to earn the right to defend the title they have won the last two seasons.
Victory retains a slim possibility of getting involved in post season play offs, but its chances are those that only mathematicians will realistically concede.
For City this was a game that simply had to yield three points. Victory's role was to be cast as party poopers, the cross town rivals who could spoil their neighbours ambitions.
