A David Williams stoppage-time header has helped Perth Glory steal a 2-2 draw with Sydney FC in a clash interrupted by a second-half power outage.
The lights went out in the 65th minute of Saturday night's game at Macedonia Park in suburban Perth, halting play for just over 10 minutes as both teams briefly left the ground.
But after being 2-0 down at halftime, Perth turned the tables and secured an unlikely equaliser when Williams got on the end of Jacob Dowse's cross and headed home.
Sydney will be left to lament one that got away after dominating much of the contest.
Star English import Joe Lolley set the tone with a sixth-minute brace in his return from a two-game suspension.
Lolley was gifted far too much space outside the box by a flat-footed Glory defence and drilled a left-footed shot off the inside of the post and into the back of the net.
The defensive lapses kept coming for the hosts, who missed a chance to equalise against the run of play in the 16th minute when Andrew Redmayne pulled off a sharp save to deny John Koutroumbis's diving header.
Sydney went 2-0 up in the 26th minute after a clearing header off Diego Caballo's curling cross landed at the feet of Rhyan Grant on the back post for a simple finish.
They should have added a third minutes later when Max Burgess hit the crossbar from close range.
Playing their fourth game in just 12 days, Perth were outclassed by a Sky Blues outfit which created chances through playmakers Caballo and Robert Mak.
Glory needed a spark and found one in the form of halftime substitute Zach Duncan.
The young gun needed less than a minute to find the back of the net with a well-timed glancing header off a Jack Clisby cross.
Perth hunted for an equaliser before the ground was temporarily plunged into darkness, prompting fans to wave illuminated mobile phones.
The clock wasn't stopped during the break in play, resulting in the announcement of 14 minutes of stoppage time.
Lolley was denied a second goal by a diving Cameron Cook when play resumed before Glory turned the tables through Williams in the 12th minute of extra time to now move to ninth on the ladder after being bottom two games earlier.
Glory are playing most of their home games this season at the 4000-capacity Macedonia Park while renovations are completed at HBF Park.
They will return to host Melbourne Victory next Saturday and have another three games scheduled at the ground next month.
