Victorian heavyweights South Melbourne have been dumped out of the FFA Cup after Hume City snatched a 1-0 win at ABD Stadium on Friday.

Nick Hegarty scored the winner on the hour to stun last season's semi-finalists at the first hurdle.

The goalscorer - Hume's player/coach - was then sent off for his part in breaking up a counter-attack with 20 minutes remaining.

That contributed to a dramatic finale as the hosts saw a possible second chalked off for offside, while South Melbourne had appeals for a penalty waved away.

Hume held firm despite their numerical advantage to stay in the hunt for a Round of 32 berth, where they exited last year.

Conversely, South Melbourne will be made to cool their heels as they fall well short of escaping the Preliminary Rounds, having been part of the final four fewer than six months ago.

They are the second Victorian giants to be knocked out in as many days following Melbourne Knights' shock 4-2 defeat to Altona Magic on Thursday night.
