Blues end winless run in style
Waterford 4 Derry City 0
Waterford were relieved to have a stroll to end their four-game winless streak.
Derry City would have leapfrogged the Blues into third with victory but their defensive frailties were once again shown up.
Dundalk and St Pat's had recently hit the Candystripes for four and five respectively and another hiding looked likely at the break.
Two cheap goals conceded from set-pieces in as many minutes underlined City's deficiencies.
Faysel Kasmi's 12th-minute corner was far from perfect but the visitors only half-cleared the danger, allowing Rory Feely to smash the loose ball home from 10 yards.
Centre-back Darren Cole, having conceded the free-kick near the halfway line, was beaten in the air by Izzy Akinade before he bundled in the second.
Five minutes before the interval, Sander Puri, who has been called up by Estonia for next week's Baltic Cup, unleashed a 35-yarder into the top corner.
Stanley Aborah, sent off seven days ago against Limerick, curled a sumptuous shot into the top corner in injury-time to complete the scoring.
