Derry City had won their past two games before defeat to Waterford
Derry City fell to a 2-1 defeat in the Premier Division away to Waterford at the RSC.
Darragh Leahy bundled home the opener minutes before the break to send the hosts in 1-0 ahead at half-time.
The host's talisman Padraig Amond doubled their lead just past the hour.
City replied late on through Liam Boyce, but Tiernan Lynch's side stay sixth in the table as their two-game winning run ground to a halt.
Wateford rip up the form book
The Candystripes side were also beaten 2-1 when these sides met at the Ryan McBride Brandywell Stadium back in February but both teams have been in contrasting form since.
Waterford came into tonight's game off the back of seven straight defeats in a run that cost manager Kevin Long his job and saw the Blues plummet into the relegation play-off place.
The Foylesiders, meanwhile, had lost just two of their eight fixtures since that February encounter.
Michael Duffy almost set them on their way to a third consecutive victory getting on the end of a Dom Thomas pullback on 14 minutes.
Last ditch defending was needed to prevent Waterford's Ryan Burke from opening the scoring moments later with his header cleared off the line.
The breakthrough did come shortly before the break as City failed to clear their lines and Leahy forced the ball into the net.
The home side had lost four of their five matches at the Regional Sports Centre prior to entertaining Derry but they took full control of the contest just after the hour when Amond's effort, aided by a deflection, flew past Brian Maher.
Sean Patton went close to reducing City's arrears on 81 minutes before Boyce eventually grabbed a consolation deep into stoppage time.
Next for Derry is a double header at the Ryan McBride Brandywell Stadium, first hosting Shelbourne next Friday before welcoming St. Patrick's to Foyleside three days later.
