Jamberoo have set up a Group Seven blockbuster with Gerringong, as Albion Park-Oak Flats stated their finals intentions by upstaging Shellharbour.
The Superoos faced a fierce Stingrays forward pack on Sunday and stared them down, prevailing 32-6 at Flinders Field.
It left the Rays without a win this season, while Jamberoo now run headlong into unbeaten Gerringong at Michael Cronin Oval next Saturday.
"It's a good start, we've got three from three," Jamberoo coach Jono Dallas said.
"There's not so much pressure on us now, we can go into the (Gerringong) game a little bit more relaxed.
"I was really happy to get (a win) today, there was a lot of talk about the Stingrays and their big pack and they needed to win, so it's a good win here."
The Eagles held off the Sharks 26-20 on Sunday, while Kiama overwhelmed Warilla 36-12.
Gerringong maintained their unbeaten run with a 54-nil demolition of Nowra-Bomaderry on Saturday.
In victory, Dallas was most impressed with the Superoos' goal-line defence, which stopped the Stingrays charge in their tracks.
"I thought the first half was really good, keeping them to zero," he said.
"There were a couple of periods where they had back-to-back sets on our try line.
"They've got some big powerful forwards and they're hard to tackl, so I was really proud of our boys.
"And our attack was really good, in the first half we scored three, but we bombed them as well, dropped them over line."
