Sligo are still looking for their first victory of 2018 following a disappointing defeat to Seapoint at Strandhill’s Hamilton Park on Saturday.
It started well for Sligo, who welcomed former Connacht forward Mata Fifita back into their squad for the game, when Shane O’Hehir claimed the game’s opening try.
Jack Keegan added the extras and followed up with a penalty as Sligo led 10-0 at the break.
But the Dublin side responded with an early second half penalty, before a converted try tied things up with 15 minutes left.
And Seapoint won it in the closing stages with another three-pointer, as Sligo suffered their third successive defeat.
The result means Sligo drop to second in the table, behind Limerick side Thomond, who beat Omagh 10-6.
