Sydney United 58 enter the second derby of the season against Marconi now in second place after a 2-0 loss to Blacktown City FC on Sunday at Lily Homes Stadium.
An early goal to Jak O'Brien and a late goal to Daniel Collins were enough for the home to secure the win and reclaim the league lead on Back to Blacktown day.
The Reds dominated field position for much of the second half but couldn't find an equaliser before conceding late in the match.
The defending champions host Marconi on Sunday. Remarkably, the Stallions had their tenth draw of their campaign against the Northbridge Bulls at Marconi Stadium on Sunday.
The home team fought back from 2-0 to secure the point in a game where eight yellow cards and two red cards were awarded with Mitchell Mallia and Marko Jesic finding the back of the net.
The Stallions have only two wins for the season, but one came against the Reds in March.
- Sydney United 58 v Marconi Stallions, Sunday, Sydney United Sports Centre, 3pm.
