The Manusians caused the upset of the day, leaving the hosts scoreless at nil-all throughout the game.
It was one of the best defensive side the visitors displayed at the Sir Ignatius Kilage Stadium (SIKS) in front of a vocal crowd.
Though it was tough in both halves, it was a relief for the Manusians to hold a top team scoreless.
Dwellers' own trusted striker Nigel Dabinyaba and skipper Raymond Gunemba were locked all throughout the game while Admiralty had a field day upfront.
