It took until the dying stages but Wellington got a deserved second goal to beat a 10-man Perth 2-1 in their A-League clash at nib Stadium.
Glory's international signings Guyon Fernandez and Diego Castro again failed to create scoring chances on Sunday, but it still took until the 89th minute for the Phoenix to put the home side away.
Richard Garcia's receipt of a second yellow card in the 84th minute opened the door for the visitors and Vince Lia obliged five minutes later, prodding home the winning goal.
But it was an otherwise largely muddling affair after a promising opening.
Glory got on the board first through Gyorgy Sandor in the seventh minute when he perfectly latched on to a Mitchell Oxborrow corner.
The Phoenix responded just two minutes later with Roy Krishna having too many tricks for Perth defender Michael Thwaite.
For the rest of the half Wellington's attacking threats of Krishna, Michael McGlinchey, Rolieny Bonevacia and Jeffrey Sarpong looked far more dangerous and creative than the Glory's Fernandez, Garcia, Castro and Chris Harold.
The scoreboard didn't show it until Lia saved the more dominant side's blushed just before fulltime.
The Glory now host an FFA Cup semi-final against Melbourne City on Wednesday while the Phoenix host the unbeaten Brisbane Roar on Saturday.
