And Derry, who lost their unbeaten record on home soil, can have no complaints as the Bit O’Red were thoroughly deserving of this victory, which all but made up for their defeat at this venue in the EA Sports Cup 10 days ago.
Sligo burst out of the traps with Derry failing to settle in the vital areas and, if the truth be told, they could have led 3-0 before 25 minutes had elapsed but for the alertness of home keeper Ger Doherty.
John Russell, Mick Leahy and Raffaele Cretaro all squandered superb scoring opportunities, Doherty denying Russell and Cretaro with vital saves.
However, the visitors deservedly broke the deadlock. A free-kick on the left from Craig Roddan saw Derry centre-back, Patrick McClean, fail to intercept allowing Cretaro to rise and direct a downward header into the net from close range.
The home side’s only note-worthy effort on goal during the opening period was a low drive from Rory Patterson midway through the half which was easily saved by Micheal Schlingermann.
A Cretaro snap-shot threatened to extend Sligo’s lead in the 52nd minute, Doherty alert to the effort when blocking with his hands.
However, Derry did begin to threaten and in the 61st minute a cross from young Conor McDermott was touched agonisingly wide by substitute, Ronan Curtis.
Minutes later, Sligo hit on the break and when Liam Martin’s shot crashed off the post before Jimmy Keohane drove the rebound against the crossbar and Derry breathed a sigh of relief.
But Keohane made up for his miss in the 64th minute when doubling Sligo’s lead, Aaron McEneff caught in possession and the Sligo midfielder gave Doherty no chance.
