Three late tries by its fleet-footed backline gave Alhambra-Union a convincing five-try, 44-21 win at the North Ground.
The Alhambra-Union backs came into their own in the last six minutes, when they scored three long-range tries and added 18 points.
The game looked safe for Alhambra-Union when captain Peter Breen kicked two penalty goals early in the second half and the lead was 26-11 after 15 minutes.
That was the signal for Zingari to attack through its forwards.
Flanker Daniel Ramsay linked with Chris Bell and Andrew Melville, who was almost unstoppable inside the 22m and scored a try as defenders bounced off him.
When Mark Hunter kicked his third penalty goal and the gap was reduced to five points, 26-21, Zingari sniffed the possibility of a win. However, it was quickly snuffed out as Alhambra-Union concentrated its attack down the right flank and attacked from deep inside its own half.
The Zingari pack had a slight edge over Alhambra-Union but its backline was not able to break the advantage line and its defence out wide was weak.
Alhambra-Union first five-eighth and captain Peter Breen was the best back on the field and scored 24 points. Wing Nick Wright sold the best dummy of the game when he scored a late try. Ben Kent was a solid defender in the Zingari midfield.
Alhambra-Union 44 (Corey McFadzean 2, Nick Wright, Peter Breen, James Willocks tries; Breen 2 con, 5 pen), Zingari-Richmond 18 (Jeremy Bekhuis, Andrew Melville tries; Mark Hunter con, 3 pen). Halftime: Alhambra-Union 20-11.
