Shelbourne 1 St Patrick's Athletic 0
The youngest player on the park proved to be the difference in a tussle between two old Dublin rivals, teenager Jaze Kabia a new hero to the long-suffering Shelbourne faithful.
The Reds' recruitment policy has seen then snap up young talent like ex-Cobh man Kabia (19) as well as old stagers such as Gary Deegan and Karl Sheppard.
And it's adding up to an impressive-looking mix for Shels, now fourth in the table thanks a 1-0 win in front of a healthy crowd of 3,054, Kabia heading in the winning goal from a corner by Sheppard.
It was over six years since the clubs last met in a league game, Pat's picking up four major trophies in that time while Shels slummed it, reluctantly, in the second tier.
But Shels can claim the rights to dominance, at least until they meet again, on the back of this win, a deserved three points.
Kabia showed a glimpse of his talent on 20 minutes, a stunning piece of ball control and then a cross into the box which was collected by Shane Farrell, though he was unable to get a shot in. On 23 minutes, Kabia had Shels in front, a well-placed header from Sheppard's corner, another successful set-piece from the Reds this season.
The away side had been unable to get into their stride, Jack Brady's goal well protected by centre-halves Oscar Brennan and Daniel O'Reilly and it took until very late in the first half for Pat's to create an opening, Brady saving Billy King's shot.
Pat's have a wealth of experience in their side but they were frustrated by the opposition and the surroundings at Tolka Park, unable to find space in a midfield dominated by the wily old combination of Gary Deegan and Ryan Brennan. There was another blow for the away side on 70
minutes when defender Rory Feely was sent off for a harmless trip on Aaron Dobbs, his second bookable offence.
Chris Forrester did test Brady with a shot on 77 minutes but a canny Shels had this one sewn up, though there was concern at the sight of an injured Kabia being helped to the dressing-room late on.
