City, yet to lose this season, fought out a dramatic 1-1 draw with Canberra United on Saturday afternoon.
 Victory then beat Western United 2-1 to extend their unbeaten run to seven matches and close the gap at the top to just five points.
City (40 points) sit head of Victory (35) and Adelaide (30), after becoming the fourth team in ALW history to have an 18-game unbeaten streak - a mark they can surpass against Brisbane Roar next Sunday.
At McKellar Park, Canberra and City were without their respective Matildas strikers Michelle Heyman and Holly McNamara.
City took the lead in the 52nd minute when Taylor Otto bundled home from a corner, getting the better of Canberra goalkeeper Sally James.
Canberra equalised in the 81st minute when City's Bryleeh Henry inexplicably played a horror back pass into the path of Aideen Keane, who took a touch past onrushing goalkeeper Malena Mieres and scored.
James stepped up to deny Mariana Speckmaier then Rhianna Pollicina late as seventh-placed Canberra moved just outside the top six on goal difference alone.
At Ironbark Fields in Tarneit, Victory took the lead in the 10th minute when a corner bobbled out to Holly Furphy, whose skidding shot somehow got past a plethora of players to nestle in the back of the net.
Kahli Johnson, playing her final match before moving to Calgary Wild, tested Victory's defence late in the half.
In the 45th minute, Victory failed to deal with a corner and an attempted clearance from Emily Gielnik nestled in her own net.
But Victory restored their lead just two minutes into the second half.
Alana Jancevski whipped a superb corner into a dangerous area and skipper Kayla Morrison rose highest to head home the winner.
Elsewhere, two goals to Sophie Hoban inside the opening three minutes were enough to deliver Newcastle a 2-1 win over Perth Glory and send the Jets four points clear of last-placed Sydney FC.
Hoban opened the scoring with a fierce cross-turned-strike in the second minute at the No.2 Sportsground.
Less than a minute later, she helped spark another attack then burst forward, where she had one close-range shot saved, before scoring from the rebound.
Perth's Ella Lincoln tapped home in the 56th minute to add some tension, and Newcastle had to hang on with 10 players after Libby Copus-Brown was sent off in the 77th minute.
