Waterford United 1 Sligo Rovers 2
Fahrudin Kuduzovic scored twice as Sligo came from behind for a big win at the RSC.
Karl Bermingham gave Blues a 19th minute lead when he outpaced defender Jamie McKenzie and then keeper Richrad Brush to squeeze the ball home.
But Rovers hit back to level on 33 minutes from a flowing move.
Matt Judge fed Conor O'Grady whose low cross was turned home by Kuduzovic from six yards.
Blues almost got back in front when Willy John Kylie headed against the bar.
But Sligo struck to win it on 70 minutes when Rafael Cretaro won possession following a defensive blunder to cross low for the well-positioned Kuduzozic to steer home.
