SYDNEY (Interstat) — Sydney opened its A-League season with a 1-0 victory over Brisbane Roar on Saturday at Allianz Stadium. The lone goal came in the 54th minute when forward Tiago Quintal finished a play assisted by substitute Nicholas D’Agostino. The match grew chippy after the goal, with four yellow cards issued in a 17-minute span, two to Sydney substitutes. Brisbane Roar failed to find an equalizer. The result defied a pregame projection from Interstat, which had simulated a 2-1 Sydney win and gave the hosts a 79.9% probability of victory. Sydney begins the campaign 1-0-0, while Brisbane Roar starts 0-1-0.
