Sydney FC remain fixed at the top of the A-League table after defeating cellar-dwellars Central Coast 1-0 at Netstrata Jubilee Stadium on Saturday night.
It was the sixth consecutive win for the defending champion Sky Blues and their eighth of the season.
A week after they thrashed Brisbane Roar 5-1, Sydney were in cruise control against the Mariners following the opening goal from Kosta Barbarouses.
It looked as though they were headed for another huge win when their Kiwi international striker scored an effortless goal in the fifth minute.
However, the visitors quickly responded at the opposite end with Daniel De Silva's shot brilliantly saved by keeper Andrew Redmayne.
The crowd of 10256 was relaxed with the lead until the 89th minute when Mariners midfielder Giancarlo Gallifuoco's header was saved by Redmayne, who was on the spot again.
But it was not to be for the Mariners, who slumped to their fifth loss of the season.
Babarouses was one of the best on the pitch once again and, after his early opener, was back on the attack in the 22nd minute but couldn't convert as Alen Stajcic's men successfully scrambled.
Brazilian forward Jair finally made his Mariners debut after recovering from a quadriceps injury.
He had a chance late in the first half from a Sam Silvera cross, but his header went just wide and they went into the sheds down 1-0.
A late surge of possession did not earn them a share of the points.
They've now won just two of their past 25 games when held scoreless at halftime.
It was the fifth loss of the season for the bottom-placed Mariners, who have still only won two games this season.
Next week they face Adelaide United, while the Sky Blues will aim to keep their winning streak alive against Wellington.
