But they were powerless to stop the Wanderers from leapfrogging Brisbane into second spot on the A-League ladder, with a first-half double-strike from Brendon Santalab sealing the points.
The Phoenix did threaten throughout, though, as both Michael McGlinchey and Roly Bonevacia were denied by the inside of the woodwork. The home side offered plenty of attacking enterprise and enjoyed more play in the final third, but the left-hand post and goalkeeper Andrew Redmayne combined to keep the Wanderers' sheet clean.
A rasping Blake Powell drive was repelled by a stunning save from Redmayne and a little more accuracy from Roy Krishna could have seen the Fijian find the net, leaving the Phoenix to rue their misfortune as Santalab decided the game.
The striker could have already earned his side a penalty, having been bundled over in the box by Tom Doyle for what looked like a legitimate spot kick, but needed no assistance from the referee for his brace.
He did, however, require a fair slice of luck for his first goal, watching gratefully as the ball rebounded off his body and barely dribble across the line, before giving his side all the ascendancy with a clinical strike on the stroke of halftime.
All that was left was for Sigmund to enjoy a ceremonial substitution and, courtesy of an errant Santalab elbow, the defender ended his career with his head swathed in bandages, a fitting adornment given the passion he always displayed.
