First-half goals from Kyle White and Kacper Radkowski paved the way for Waterford's first win at the Brandywell in four years, with a 2-1 victory over Derry City.
FULL MATCH DETAILS
It was a lethargic display from the hosts, who did come back into the contest courtesy of Pat Hoban’s 74th-minute penalty.
Despite creating opportunities to equalise, they failed to do so as Waterford, who didn't score in four games against Derry last season, climbed to second in the standings after six points from their opening three games.
Kyle White opened the scoring after just nine minutes with a smart strike past Brian Maher before the Blues doubled their advantage shortly before the interval.
Conor Noonan’s free-kick found Radkowski at the back post, and the Polish centre-back's drilled shot from an angle put his team in the driving seat.
Gavin Whyte and Mark Connolly missed big chances for Derry before Noonan failed to finish off a counter-attack to make it 3-0 to the visitors
Navajo Bakboord’s foul on Ben Doherty in the area gave Derry fans hope when Hoban dispatched from the spot.
There was drama at the death then when the home side threatened to rescue a draw, but Robbie Brennan miscued from six yards out.
