Added to all that was PBC out half Kevin Kidney had an almost perfect day with his kicking in tough conditions, seven conversions and a first-half penalty which opened his side’s account on top of his 23rd-minute try bringing his personal total to 22 points.
The Limerick school had started off the day’s scoring with their own number 10, Jamie Gavin, sending over a long-distance penalty after six minutes however within four minutes Kidney had wiped out the only lead Ardscoil would hold all day.
But it wasn’t until the 20th minute that Pres got the first of their nine tries. Centre Johnny MacCarthy had been denied in the corner but the resultant lineout was turned over thanks to alert flanker Jack Duffy who then fed his fellow wing forward, Conail Murphy, who made it 8-3 with a successful conversion to come.
Ardscoil struck back with a penalty but after Murphy set up Kidney’s touch down, there was only going to be one winner.
In the 27th minute, Pres centre Cian Bohane who was alive to a wayward Ardscoil pass inside his own half, latched on to the loose ball before kicking the ball ahead of him twice as he outsprinted his opposing backs to allow him a deft pick up just before the line to complete the score.
It was 20-6 at the break, not an impossible task for the Limerick boys but early tries in the second and fourth minutes of the second half from wing Patrick O’Connell and scrum half Ronan Barry, both converted, were the killer blows they didn’t need.
Prop Ian Mullarkey added one of his own five minutes later thanks to a nice break from full back Jack Costigan and so with Kidney kicking over, the scoreline moved out to 41-6.
Duffy made his own mark on 52 after a great run and quick pass from excellent lock forward David O’Mahony and with Kidney on target again, the gap was now 42 points.
But after a sustained period of pressure, Ardscoil showed they still had some fight in them, their pack rolling over for a try which replacement prop John Canny claimed.
With just three minutes to go, PBC captain Niall Scannell got his side’s eighth try before MacCarthy finally got his own reward for an impressive performance.
Pres will now play Crescent Comprehensive while Ardscoil have the arduous task of taking on Christians for a place in the semis.
