Central Coast Mariners cruised to a 1-0 victory in their midweek clash with North Queensland Fury at Bluetongue Stadium on Wednesday night.
A first-half goal to Adam Kwasnik was all that was needed to give Graham Arnold's men their ninth win of the season.
The striker's emphatic header in the 28th minute was his eighth goal of this A-League campaign, and pushed the Mariners past Gold Coast United on goals scored, and subsequently into third spot on the ladder.
Despite the narrow margin, the home side rarely looked troubled against a conservative Fury outfit that ultimately lacked creativity in the final third of the pitch.
Both sides fielded near full-strength line-ups, with the Mariners handing playmaker Patricio Perez his third start of the season in behind strikers Kwasnik and Matt Simon. The Argentine was lively from the opening whistle, setting up numerous opportunities during his 61-minute stint.
In just the seconod minute, it was Perez who found space in the middle of the park before playing in Kwasnik down the right flank, but the striker's shot was straight at Fury goalkeeper Justin Pasfield.
The visitors were forced to play the majority of the game on the counter-attack, sitting deep and absorbing defensive pressure as a result. On the few occasions that they did break quickly in the first half, striker Chris Payne was denied by fine saves from keeper Matt Ryan.
The game would be decided midway through the half when New Zealand international Michael McGlinchey opened up the Fury defence with a neat ball to Simon down the right. His ball to the far post was headed home with authority by Kwasnik, giving the Mariners a lead they would hold for the rest of the match.
The second half, though, was a scrappy affair with the midfield becoming increasingly stretched.
The only genuine chance of the half fell to the feet of Simon, who really should have put the game beyond doubt in the 72nd minute. After being played clean through on goal by a delightful Mustafa Amini chip, Simon fluffed his strike when one-one-one with Pasfield, giving the Fury a lifeline.
It was an opportunity they would be unable to take though, despite throwing on the attack-minded Dyron Daal and Jason Spagnuolo in desperate search of an equaliser.
The loss sends the Fury back to Townsville stuck in ninth place on the ladder, six points adrift of eighth placed Melbourne Heart above them, and with only one win in their past five outings.
