De La Salle clinched a first Belfast Senior Cup success since 2010 with a 3-2 comeback victory over St Mary's GS in Monday's decider at New Grosvenor.
Gary Donnelly's penalty gave St Mary's an early lead but De La Salle hit back with a Nathan Watters header.
Liam McKenna scored direct from a corner to put De La Salle ahead and Chris McGuinness fired into the bottom in to make it 3-1 after 55 minutes.
Donnelly pulled one back from another spot-kick with four minutes remaining.
Donnelly opened the scoring on seven minutes after Ciaran Seacroft was fouled by Sean O'Hanlon.
Watters sent a looping header in from the edge of the box seven minutes later and McKenna netted from a corner on 44 minutes.
McGuinness slotted home De La Salle's third 15 minutes into the second half and they held on for victory after Donnelly, who was fouled, converted his second penalty.
