A hat-trick apiece from Darragh O’Connor and Ethan Varian was enough to see Greenwood secure the National Cup with a scintillating attacking display.
But it was Corduff who made the better start and they almost took the lead within the opening seconds. But after being sent through on goal by James Sheridan, winger Sean Enright clipped the ball wide of the far top left corner.
The Dublin club did take the lead after just two minutes as Adam Muhall expertly hooked his volley over the keeper and into the far top left corner from just inside the box.
Greenwood responded well to that set-back and they duly equalised after eight minutes when Darragh O’Connor drilled Aaron Walsh’s pullback into the roof of the net.
The frantic start continued as the Cork side completed the turnaround after just 10 minutes when Cathal Crowley fired the rebound home from a few yards after Ethan Varian’s initial effort was saved by keeper Eugene Prodanchuk.
But back came Corduff and they levelled terms just shy of the half-hour mark when Sean Enright slotted Adam Mulhall's square ball past the helpless goalkeeper.
The match continued to swing from end to end as Greenwood retook the lead thanks to Aaron Walsh only for Corduff to make it 3-3 before the break when Jake McGarry found the net.
But the second period was all about Greenwood as Darragh O’Connor again edged Greenwood in front in the 50th minute before doubling their lead and completing his hat-trick in the process with a fine finish four minutes later.
Ethan Varian deservedly added his name to the scoresheet just a minute later to net his side's sixth of the afternoon.
And the talented forward completed the scoring as he made it seven with 20 minutes remaining, finishing well when through on goal before sealing his own match ball from the penalty spot late on.
