South Coast Wolves put on a clinical display to defeat Rockdale City Suns 3-1 at WIN Stadium on Sunday.

In one of their most polished performances under coach Nahuel Arrarte, the hosts were dominant from the outset and scored in the opening two minutes before sealing the result through Lachlan Reus late in the second half.

Arrarte said the display showed his side's renewed confidence in the top grade.

"I believe in the boys and you can see they are starting to believe in themselves," he said.

"We don't want to get too far ahead of where we are at, but we will continue with how we are going.

"I am happy with the result."

The Wolves stole the ascendancy just two minutes into Sunday's stoush, via the head of James Baldacchino.

The young defender rose highest from a Matt Bailey corner to head home his first goal in Wolves colours and give his side the dream start.

Rockdale tried to level inside 20 minutes, but Sean Symons had his effort well saved by Tom Hamilton.

Denied at one end, the Suns fell further behind at the other after a skilled passage of play ended with a goal to Jordan Murray.

Sam Matthews dummied over the ball outside the box for Reus to run onto and whip in a cross for Murray to poke home in the six-yard box.

It was nearly three and game over on the half hour mark, but Bailey saw his free kick sail just wide of the mark.

Down 2-0 at the break, Rockdale started to gain momentum early in the second half.

Their pressure was rewarded on the hour with a goal to Steven Hesketh.

They continued to press the Wolves for an equaliser as the tension rose around WIN Stadium.

But Reus put them to rest in the 81st minute after slamming a right-foot strike into the bottom corner after an incisive pass from Ricky Zucco.

"We spoke about it before the game - our midfielders making blindside runs and obviously a couple of goals came out of that.

"I was very happy to see that," Arrarte said.

The win was South Coast's third straight strong performance at home - they drew with Sutherland and demolished Manly.

"If you are going to be a competitive side you have to make sure you win at home.

"We have a lot of supporters and we owe it to them.

"We started off slow this year and now it is a matter of we have to continue to drive that. It should be a fortress."
