Dapto Dandaloo defeated Albion Park twice in as many days to knock the White Eagles out of the Bert Bampton Cup on Sunday.
After overcoming their rivals 3-2 in an Illawarra Premier League round seven battle on Saturday, the Fury did the double at Dandaloo Sports Ground with a 1-0 win.
A moment of class from Shaun McRae midway through the second half provided his makeshift squad with the vital goal to progress to the quarter-finals. The former youth grade leading goal scorer weaved through from 10 metres inside the White Eagles' half to eventually squeeze his shot past Volkan Gudan.
It was the only goal in a dull affair which featured two line-ups vastly different to those that took the field 24 hours earlier.
But Fury coach Norm Boardman had no complaints about how his team ground out the result.
"It was pretty disjointed but on the balance of possession I would have been really disappointed if we didn't get something out of it," Boardman said.
"They had two really good chances but other than that I think we did a really good job.
"The character is first class ... it is fantastic and that's what gets you results when you have to scrap it out like we did today."
The win followed up the Fury's come from behind victory the day before at Terry Reserve.
Goals to Doug Woodiwiss and Andrej Gacesa cancelled out Sam Munro's opener to have the White Eagles leading 2-1 at half-time.
But the league-leading Fury fought back and found an equaliser through Noel Spencer before American Joe Crowley stole the points.
It kept Dapto Dandaloo unbeaten on top of the competition and started off what was a frustrating weekend of near-misses for Albion Park coach Steve Micevski.
"We need to take our chances. Both games I think we probably could have got more out of it and we didn't," Micevski said.
In Sunday's other game, Woonona and South Coast shared the spoils in a 0-0 draw.
