Western Sydney made it back-to-back wins for the first time this season when they upset Adelaide United 3-1 at Coopers Stadium.
Wanderers opened up a 10-point gap above bottom side Central Coast Mariners, who they beat last time out.
They were inspired by Dutchman Roly Bonevacia, who set up their first goal for Oriol Riera and restored their advantage after Ryan Kitto had levelled.
Adelaide saw Craig Goodwin fail from the penalty spot, with keeper Vedran Janjetovic making a good save.
Riera stooped to head home Bonevacia's free-kick and give the visitors the lead on 12 minutes, while four minutes later Janjetovic kept them in front with the penalty stop.
The Reds missed that chance to equalise, with the penalty having been given for Brendan Hamill's trip on Jordy Thomassen, but a minute before the break Kitto made it 1-1.
He lashed home after Janjetovic came to punch Michael Jakobsen's lofted ball into the box.
Bonevacia had a slice of luck for his goal, with the ball taking a big deflection off Ryan Strain and leaving keeper Paul Izzo wrong-footed.
He claimed his second assist of the match 19 minutes from time, lifting a clever pass in for Abraham Majok to lob the onrushing Izzo.
It's the first time since February 2018 Wanderers have won consecutive matches, but their chances of rallying to make the Finals Series are slim – they are 12 points behind sixth-placed Wellington, with eight rounds to go.
The damage was done over a 10-game spell starting in mid-December when they picked up just two points.
Adelaide are 6/4 to win their next game against Newcastle, who are 7/4 with the draw 23/10.
The Reds are 17/2 to win 1-0.
