Tim Tector's unbeaten 41 helped YMCA beat Clontarf by 13 runs in the U19 final at Castle Avenue.
The Ireland U19 international hit 3 fours and 2 sixes in his 21-ball innings, which along with double figure contributions from Max Collins (24) and Mikey O'Reilly (11) saw YM post 89 for 2 in the ten-over contest.
David Vincent (23) and Ben McCabe (21) gave Clontarf hope, but with the required rate ever increasing scoreboard pressure told with two wickets apiece for Cillian McDonnell and Yash Balasubramanium.
In the end the Claremont Road side secured a 13-run win and the trophy.
