Derry City 1 Sligo Rovers 2
Derry slumped to a fifth successive defeat to all end their European hopes as Sligo moved three points clear of the relegation playoff zone.
Talismanic striker Raff Cretaro fired home his fifth goal in as many games, and his 15th of the season, to put Sligo in front on six minutes.
Derry leveled through David McDaid nine minutes later.
But Rovers battled back to win it on 61 minutes through Benin international Romuald Boco.
