Teenagers Alex Gleeson, Jack Walsh and Dan Holland all won their matches to give Castle a 3-2 win over All Ireland champions Portmarnock at Hermitage and the first Senior Cup pennant in the club’s 99-year history.
Gleeson, soon to be named alongside the Island’s Gavin Moynihan in the Great Britain and Ireland Jack Leglise side to face the Continent of Europe at Portmarnock next month, beat James Fox 5 and 4 to level the match after Conor Deegan had lost to Geoff Lenehan on the 19th.
Jim Mulready lost to 2011 South of Ireland champion Stephen Walsh 2 and 1 but Castle took the last two matches to seal a memorable and long-awaited victory.
Walsh beat Michael Brett 3 and 2 before Holland saw off Carlow’s John Greene, another former South of Ireland champion, on the 16th.
