CLONTARF 9 BLACKROCK COLLEGE 3, Castle Avenue
Scorers: Clontarf: Pen: Martin Dufficy; Drops: Martin Dufficy 2
Blackrock College: Pen: James Power
Martin Dufficy, the former Ireland Under-20 out-half, kicked 'Tarf into the lead with a second half drop goal and then he sealed the result with a crisply-struck penalty on 73 minutes.
Blackrock's enviable back-line, brimful of Leinster Academy talent, failed to get going and Clontarf deserve credit for keeping it tight, where openside flanker Peter Synnott revelled.
'Tarf scrum half Paul O'Donohoe also exerted plenty of influence, while experienced lock Des Dillon and assured full-back Niall Morris both impressed for the visitors who also lost at this venue last season.
