Ten points from the boot of Conor Linehan set Castletroy College on their way to a semi-final spot after a hard-fought win over Glenstal Abbey at the University of Limerick.
Linehan put on a terrific display of goal-kicking as he landed four of his five kicks in blustery conditions on UL's artificial surface. The full-back got off to a shaky start and missed a kickable penalty with the wind behind him after just three minutes, but he soon made amends.
Fly-half Mark McCarthy's exquisite vision put Paul Butler in for the game's opening try and Linehan then fired over a superb touchline conversion.
Ten minutes later, Castletroy scored their second try when hooker Mark O'Mara – nephew of former Ireland international Peter Clohessy – was on the end of a powerful rolling maul from a five-metre line-out. From almost the exact same spot as his previous conversion, Linehan added the extras to give his side a 14-0 half-time lead.
Jack Stafford put Glenstal on the scoreboard with a well-struck penalty shortly after the restart to give the Murroe-based school renewed belief.
Linehan responded with a penalty of his own before Jamie McAleese found a huge hole in the Castletroy defence to touch down under the posts. Stafford converted to bring the score back to 17-10. Glenstal continued to pile on the pressure but, eight minutes before the end, Linehan made the game safe with another fine penalty to seal Castletroy's semi-final place.
