Firing on all cylinders from the off, St Colman's, playing with the near gale-force wind, shattered Nenagh's ambitions with a free-flowing first-half performance.
With full-forward Adrian Mannix on song, St Colman's opened the floodgates early on, with a series of brilliant points which left Nenagh fighting an uphill battle.
Mannix, Eoin Barry, Shane Kearney and Stephen Walsh scored some real beauties as St Colman's swept into a six-point lead, before centre-forward David Gleeson opened Nenagh's account with a pointed free in the 15th minute.
This proved to be Nenagh's only score in a first half totally dominated by St Colman's, illuminated on a piercingly cold afternoon by the exciting individual skills of midfielder Shane Cotter, half-forwards Walsh, Barry and Kearney and full-forwards Mannix and Mark O'Callaghan. Nenagh placed two markers on Mannix, but to little avail.
The difference in class between both sides was graphically illustrated a minute before the break when Walsh, with a great cross-field pass, set up O'Callaghan for a peach of a goal that left St Colman's leading 1-13 to 0-1 at half time. It appeared even at this stage that Nenagh's chance was over.
However, Gleeson had their second point from a free in the 38th minute. Wing-forward Robert Duff followed with a goal five minutes later and both Tony Dunne and Gleeson, in what was Nenagh's most telling period, added two further points to reduce the deficit to nine-points entering the closing quarter.
But because of the excellence of the St Colman's defence, in which Don O'Connell, Kenneth Kearney, James O'Sullivan and Liam Coleman played leading roles, Nenagh were unable to make any further in-roads and, finishing on a high, the Fermoy students copper-fastened their runaway 13-points triumph with a goal from Shane Kearney on the stroke of full time.
St Colman's now meet old rivals St Flannan's in the semi-final on Sunday week in what promises to be a cracker.
