Earlier, Trinity forced extra-time when Barry Glavey netted a last minute drag-flick to end what had been a fast and frantic 70 minutes.
It was Glavey’s second of the game having earlier exchanged corner strikes with Rob Abbott in the first half. Tom Noonan’s superb deflection, though, looked to have given the north Dublin side the title with less than ten minutes remaining.
However, a scoreless extra-time preceded strokes with Jack Hegarty saving twice to put Trinity in the box seat and eventual victory.
The game also marked Gordon Lindsay’s retirement after an impressive career at Dublin Uni, Clontarf and Three Rock Rovers in which he claimed a couple of division two titles with Trinity and current club Clontarf and a division one title with Bert Vreeken’s Rovers.
