It occurred within the 10 minute, by which era Keogh ended his five-game run with no purpose. He added a second within the dying seconds of the sport.
After the sport resumed, former Mariner Ferreira scored two targets to provide his aspect a Three-Zero half-time benefit and arrange a three-point lead on the high of the desk.
They have been the primary targets in 23 months for the Portuguese ahead whose final one satirically was a penalty for the Mariners towards Perth on the identical floor in January 2017.
The loss meant Central Coast went via 2018 with only one A-League win in 24 video games and have gone 15 matches since their final victory.
They received off to the worst attainable begin, conceding within the third minute when Glory captain and striker Keogh slotted the ball residence after the Mariners did not correctly clear a ball into their penalty space.
Within the incident which led to the snapped put up, Mrcela headed the ball into the web earlier than charging into it, but it surely was disallowed for offside.
The delay allowed the Mariners to regroup and so they did initially present extra depth after the restart.
In a single passage of play, Mariners goalkeeper Adam Pearce saved a Joel Chianese shot, the defence blocked one other try and a 3rd effort went huge.
Nevertheless it was a short lived reprieve as Glory doubled their lead inside three minutes, when Ferreira headed residence a Jason Davidson cross.
Ferreira struck once more simply earlier than half-time, when his cross floated over Pearce into the far nook of the web.
That was sufficient for some disgruntled Mariners supporters, who left after the purpose, whereas others booed their aspect off at half-time.
The Mariners had extra possession within the second half and substitute Jordan Murray went shut twice earlier than scrambling the ball residence within the 78th minute for his first A-League purpose.
