Bottom side Wellington Phoenix ended a seven-game winless streak as they beat Melbourne Victory 2-1 at Westpac Stadium thanks to a late own goal.
It was just the second victory of the campaign for Darije Kalezic's side, and they had luck on their side for both their goals.
Wellington had an extra man from the 10th minute, after Rhys Williams was dismissed for the visitors.
The Victory defender took out Phoenix striker Andrija Kaludjerovic on the edge of the box as he was clear on goal. Referee Matthew Conger initially gave Williams a yellow card but then after taking another look with the help of the Video Assistant Referee decided to upgrade the sanction to a red card.
Kalezic made a tactical change in sending on attacking midfielder Nathan Burns for centre back Marco Rossi to try to exploit their extra man, but initially it backfired as the game opened up and Victory were able to take the lead.
Five minutes before the break former Wellington man Kosta Barbarouses went on a quick counter-attack before Lewis Italiano at his near post, the keeper getting his left hand to the ball but unable to keep the shot out.
For a time things went against the Phoenix as they had two goals ruled out just before and just after half-time.
Nathan Burns was denied an equaliser by the assistant referee's offside flag, though replays showed the decision had been wrong, then Andrija Kaludjerovic was also flagged for offside.
The home side were fortunate to get back on terms when Burns' shot crept through the legs of keeper Lawrence Thomas and Roy Krishna was able to rush in and poke the ball into an empty net.
The Phoenix winner came seven minutes from time when defender Dino Djulbic poked a Burns cross into his own net.
Melbourne Victory are 19/20 to win the Grand Final.
Victory are 4/9 to win their next game, 15/4 to draw and 6/1 to lose to Perth Glory.
