Heidelberg United have continued their fairytale season, defeating fellow NSL old-timers Sydney United 4-3 on penalties to join Adelaide in the FFA Cup quarterfinals.
Wednesday night's round-of-16 clash went down to the wire at Sydney's Edensor Park, where the scores were locked at 1-1 after extra-time.
The odds swung in Heidelberg's favour when Panagiotis Nikas missed the first spot-kick, and goalkeeper Christopher Theodoridis sealed the deal by saving Yianni Fragogiannis' attempt.
The triumph caps a huge month for Heidelberg, who eliminated Perth Glory in the Cup's round of 32 before winning Victoria's Dockerty Cup and becoming state NPL premiers last weekend.
George Katsakis' side thought they'd got the job done in extra-time when, after 110 goalless minutes, talented left-footer Sean Ellis buried Kenny Athiu's flicked header.
But, with just under 90 seconds remaining, super-sub Adrian Vranic equalised with a low finish after an excellent Nikas through ball.
Down at Adelaide's Marden Sports Complex, the Reds scored thrice after the break to recover from a tough first half and crush A-League opponents Melbourne Victory 3-0.
New Danish recruit Johan Absalonsen struck first with a belter from outside the box that swerved and tucked inside the post.
Former Sydney FC striker George Blackwood doubled the lead from the spot before Nathan Konstandopoulos sealed the win with a delightful 90th-minute curler that left Lawrence Thomas dumbstruck.
The goalkeeper wasn't nearly as stupefied as winger Mitch Austin, who was veritably flattened by a Taylor Regan tackle and somehow returned to play as Victory dominated early.
Meanwhile, Gold Coast City triumphed 1-0 over fellow NPL Queensland opponents Moreton Bay United.
Extra-time was delayed for 10 minutes thanks to a blackout at Albany Creek's Wolter Park, forcing an electrician to save the day and allow coach Grae Piddick's side to triumph over Moreton Bay, for whom his brother Adam Piddick is technical director.
At Lakeside Stadium, South Melbourne were far too good for 10-man Sorrento, prevailing 4-1 with Nick Epifano netting a double.
