Rebecca Lowe was once again the hero as Lisburn chased down 143 to beat Clontarf and clinch the Under 15 Girls All-Ireland trophy at Jack Harper Park in Balbriggan.
Batting first, Clontarf skipper Genevieve Morrissey hit 6 fours in a half century (52), adding 82 for the second wicket with Sinead Thomson (43).
Rebecca Lowe impressed with the ball taking 3 for 14 denying Clontarf a strong finish, although the concession of 32 extras boosted the total of 142 for 6.
The Lisburn chase started badly with captain Grace Wilson going early, but Lowe and Amelia Hughes set about building a match winning partnership.
Rebecca hit 8 boundaries in her 66, sharing a second wicket partnership of 101 with Amelia Hughes (39*).
There were a few nerves following the run out of Lowe, but Hughes and Lucy Humphries (11*) ensured what was in the end a straightforward race to the line, sealing the eight wicket win with two overs to spare.
Another youth All-Ireland trophy for Lisburn following their double glory last year, and they have the chance of another if their Under 13's girls can beat Holywood next week to claim the NCU title.
