Fermanagh completely dominated a second half that saw them outscore Sligo 0-10 to 0-3 and the visitors reduced to 13 men by the final whistle.
An even enough first half saw Sligo go in at the break a point to the good having rattled off 1-3 in the last seven minutes of the first half with Fermanagh responding with just a point but it was a very different Erne 15 that returned for the second half.
Sean Quigley was the undoubted star of the show for the home side. In the second half he added seven points to a tally of 1-1 in the first half to emerge as the game's outstanding performer. He was ably assisted by his full-forward line partners Tomas Corrigan and Eamon Maguire who were a constant threat.
Sligo were below par and only Adrian Marren – with five points – and Charlie Harrison in defence emerged with any real credit.
Ryan Jones hit Fermanagh's second goal to shoot his side into a four-point advantage with the first half drawing to a close but Sligo responded with the next attack through Mark Breheny who kept his cool to finish a flowing move.
But the half-time whistle was the best it got for visitors as Pete McGrath's men took over after the break to secure their first competitive win under the Down man's tenure. For Sligo it was a long road back west.
