Hannah Grieve top scored with an unbeaten 86 as the NCU hammered the NW by 165 runs in their interprovincial clash at Fox Lodge.
Grieve hit 5 fours and 4 sixes in her knock, as the visitors piled up an imposing 252 for 4 in their 40 overs.
The Lurgan batter shared stands of 80 for the fourth wicket with Irish international Cara Murray (41) and an unbroken 68 for the fifth with Waringstown captain Charlotte Lyons (26no).
The NCU innings had been given a solid foundation with an opening partnership of 71 between teenage Irish international Amy Hunter (38) and Amy Caulfield (22).
Mollie Devine (2-35) was the pick of a beleaguered Warriors attack.
The chase never got going as wickets for Staci Maxwell, Cara Murray and Nikki Niblock left the innings in tatters at 41 for 7.
Alana Dalzell's unbeaten 43 spared some of the blushes, but the hosts were 87 all out, losing by 165.
A harsh lesson for the North West, but one from which they will hopefully grow and learn.
