he Sky Blues continued their dominance over the Wanderers, courtesy of Adam le Fondre and Alex Brosque goals either side of half-time on Saturday night at the SCG.
But yet another howler from the video assistant review system (VAR) will steal headlines after Babbel had been marched midway through the second half.
Western Sydney winger Roly Bonevacia appeared to have set up a grandstand finish when his low shot beat Andrew Redmayne at his near post.
However upon review, referee Chris Beath ruled a retreating Jaushua Sotirio impeded Michael Zullo from defending the Joshua Risdon cross in the lead-up.
Replays showed a falling Zullo appearing to take full advantage of Risdon running back from an offside position.
Babbel was immediately incensed, flinging his jacket off in disgust and remonstrating with fourth official Benjamin Abraham.
The rookie coach kicked the advertising hoarding when shown red by Beath, and gave a standing Red and Black Bloc a thumbs up on his way out.
The VAR incident came hours after Melbourne City were angered by a missed penalty shout for Bruno Fornaroli earlier on Saturday against Central Coast.
It also came after more VAR drama in Friday night's Adelaide-Newcastle game, and days of criticism which followed last week's Melbourne derby.
The SCG saga overshadows another derby win for the Sky Blues, who have lost only one of their past 15 matches against their fierce rivals.
The first football match at the SCG in more than 30 years drew a crowd of 30,588.
It didn't take long for the home side to assert their dominance, with le Fondre netting his second goal in as many games in the early season.
