In a game played in glorious sunshine, the boys from Threadneedle Road emerged victorious after a very competitive encounter between two equally matched teams.
It was St. Mary’s who opened the scoring after eight minutes with a penalty. Emil Hernon scored a penalty to even up the scores after 15 minutes.
A superb individual try again from Hernon saw Colaiste Einde go in at half-time leading by 5 points. An Andrew Rogers try, soon after the restart, left the Salthill youngsters 15-3 in front.
The boys from Ballygar produced an excellent fight back late on bringing the score to 15-11 and with a few minutes on the clock it looked like they would get the crucial score.
However, a fantastic defensive display saw Colaiste Einde hold out for an historic victory.
The RBS 6 Nations and Triple Crown trophies were on hand and both teams were delighted to get a chance to be photographed with them.
