Having inflicted a 68-5 defeat on Ulster in their opening game in the Under 18 Schools Championship, they left no doubt they are one of the finest ever teams to grace the competition when disposing of Munster at Thomond Park yesterday.
Apart from the opening quarter when Munster performed with customary fire and vigour and carried the fight to their vaunted opponents, there was absolutely no doubt as to the superior side.
Leinster were far stronger physically and there was also a very evident gulf in class, especially behind the scrum where the footballing acumen of out-half Ross Byrne and full-back Billy Dardis was constantly to the fore while a much faster three-quarter line proved a constant danger.
Munster were left to rely on the boot of Crescent College out-half Gearoid Lyons for all their points. He also performed well in general play, as did the Ard Scoil Ris full-back Stephen Fitzgerald, Crescent No 8 Cormac Blake and the PBC pair Morgan Carey and David St Ledger.
But as a unit, Munster were always playing second fiddle even if the opening minutes did see them take the lead through a Lyons penalty. It took Leinster a little longer than they might have expected to impose their will but once Cistercian College, Roscrea, second-row Rory Moloney forced his way over for a try at the posts in the 24th minute and Ross Byrne added the points, there could be only one outcome.
Lyons and Byrne exchanged penalties in the space of a couple of minutes but shortly afterwards Leinster salvaged a dangerous looking situation inside their own 22 before launching a devastating counterattack which ended with right winger Cormac Brennan, also from Roscrea, diving over in the right corner, from where Byrne converted with a fine kick.
Leinster turned round 17-6 in front and even though a couple of Lyons penalties to one by Byrne left only eight points between the teams with 20 minutes still to play, Leinster remained very much in the ascendancy.
Scrum-half and captain Nick McCarthy was constantly probing and his sniping break led to his side’s third try for Clongowes centre Fergal Cleary.
Byrne converted and was again on target when James McCormack of Castleknock went over to stretch the advantage to 34-12.
It was all Leinster at this stage and only a questionable touch judge decision against McCormack deprived him of a second try.
Elsewhere, two tries from Conor Shiels saw Ulster U18s recover from last week’s mauling at the hands of Leinster to hand out a 23-0 defeat to Connacht at the Sportsground yesterday.
Shiels crossed either side of half time and winger Rory Campbell touched down five minutes from time to inflict a second defeat of the competition on an outclassed home side.
