COLáISTE PHáDRaIG CBS's first-year side completed an incredible season by retaining their Dublin Metropolitan League Cup crown.
The Lucan school's youngest group followed in the footsteps of their treble-winning predecessors from last year by bringing home silverware.
Manager Ray Cullen's new-look group ensured the school retained their Leinster Cup title with a slender final win over Athlone's Marist College.
Despite last week's penalty-shootout defeat to Rochestown Community School in the All-Ireland semi-final denying Phadráig the chance to also retain that title, they finished on a high with county glory on Tuesday.
An extra-time winner from striker Yasser Mahrouk was enough to give Phadráig victory over Ashbourne Community School.
However, it took a last-minute penalty from captain Emmett Allen to rescue the west Dubliners and force extra-time.
Goals either side of half-time had seen Ashbourne cancel out a Luke Walsh opener and Phadráig had to dig deep to turn the scoreline around.
They had not been so lucky five days earlier in Waterford when Munster champions Rochestown qualified for the national final thanks to a shootout win.
Cullen was delighted with Tuesday's season finale and insists his side's determination alone merited a successful end to a great season.
"We can be honest and say the better team won the All-Ireland semi-final deservedly, but we deserved this win and we got it," said Cullen.
"The players were absolutely magnificent, never gave up and showed the kind of character that has served them so well all season."
