Sydney FC have further established themselves as the competition's best with a 1-0 win over Brisbane Roar on Friday night.
It has now been 12 games since they were last defeated, with Friday's victory propelling them 13 points clear of Melbourne City on the A-League ladder.
However, Robbie Fowler's Roar didn't go down without a fight, putting in a brave performance with 10 men for the majority of the second half at Netstrata Jubilee Stadium.
Scott Neville was given his second yellow card for a handball in the box and subsequently marched in the 57th minute, leaving the league's most prolific scorer Adam Le Fondre with an ideal chance to open the scoring.
He made light work of the resulting spot-kick, rocketing the ball into the net past Jamie Young for his 15th goal of the season.
The crowd of 10,724 watched on as Roar scrambled to hold on through an onslaught of shots from the surging champions.
Young rose to the challenge and made two spectacular saves 10 minutes later under pressure from Luke Brattan and Le Fondre.
And he held firm when Anthony Caceres took aim in the 72nd minute.
The loss ended a five-game undefeated streak for the visitors, leaving them just outside the top six.
The Sky Blues will next face Western Sydney in the derby at Netstrata Jubilee Stadium, while the Roar will take on Adelaide United in round 18 action at Suncorp Stadium.
Earlier in the day, Sydney FC took out the Y-League championship with a convincing 5-1 win over Melbourne Victory.
