Sydney moved 10 points clear at the top of the A-League as Alex Brosque and Milos Ninkovic secured a 2-0 victory over Brisbane Roar.
The league leaders did not have it all their own way, though, and had to play the final 25 minutes with 10 men after Brosque was shown a red card for two bookable offences.
After a frenetic start, the game finally had its opening goal with nine minutes of the first half remaining.
Bobo got a bit of luck with a ricochet on the halfway line and took full advantage with a surging run towards the Brisbane penalty area before finding Brosque, who slotted home his eighth of the season.
