That trend continued until half-time, with Dillon and Sorcha McNulty doing the damage as Ide led 43-21 at the midway point. Dillon kept up the pressure with a three-pointer as Ide extended their lead to 23 points in the third quarter, but Enya Brady responded with three of her own, before Aoibhinn Byrne reduced the lead further.
But the Dubliners could not get close enough and Abbeyfeale closed it out.
