With the Mariners looking tired from having to play on Thursday the, comparatively, rested Wanderers tore the Central Coast apart with their speed leaving the Mariners no chance.
The Wanderers started the match well, tearing the Mariners apart through the opening 20 minutes when the goal came.
It was a deflection from Marcel Seip that allowed the Wanderers to take the lead, as Iacopo La Rocca's shot deflected off the Dutchman as Tomi Juric was left unmarked and scored the goal.
It wasn't a simple finish for Juric though, as he pulled out a potential goal of the season as Juric shifted his body and managed a bicycle kick that left Liam Reddy with no chance.
That seemed to wake up the Mariners who started attacking and could well have found an equalizer almost immediately as Josh Rose's effort was blocked.
Marcos Flores should have got the Mariners back on level terms moments later with the goal at his mercy but was denied as Matthew Spiranovic who slid in and cleared the ball away.
In the 33rd minute the Mariners were punished for missing their chances as Western Sydney made it two with Shinji Ono sending a cross across the face of goal to find Youssouf Hersi who hit a powerful strike home to make it 2-0.
The momentum then went back to exactly where it was with Western Sydney dominating but the Mariners held on, getting to the break just two down.
Western Sydney continued their domination after the break and really could have had a much bigger league with Jerome Polenz looking dangerous throughout.
Indeed it was Polenz who had the best chance of the half as his volley scraped the bar heading over the bar, letting the Mariners off the hook.
It could have easily been four, or even five, for the Wanderers as they were all over the Mariners throughout the match but couldn't find any more goals, settling for a 2-0 win.
