Academy graduate, 19 year-old Evan McLaughlin enjoyed a dream debut with a first half goal to set the Candy Stripes on their way to an important victory.
Joe Thomson then made sure of the points with a classy finish eight minutes into the second half which ended Waterford's hopes of a comeback.
It was a professional display by Ruaidhri Higgins' men which ensured they leapfrogged Dundalk back into six in the table ahead of a tough trip to title challengers St Patrick's Athletic this Friday night.
Derry boss Higgins clearly likes playing an attacking 3-5-2 formation and it's worked well in the second half against Dundalk and then again against the Blues last weekend.
New signings Junior Ogedi-Uzokwe and Jamie McGonigle also got much needed game time under their belts as they integrate into the team as Higgins used 15 players in total but which of the club’s players took their opportunity to shine?
Here, we take a look at how every player fared in the comprehensive 2-0 victory.
5. Ronan Boyce
Pushed further up the pitch in a wingback role on the right and looks just as comfortable as when playing in a back four. Joined in with the attacks well and showed he has more in his locker than solid defending and scoring late goals.
6. Nathan Gartside
A spectator for much of the first half, the City keeper was called into action twice in the space of five second half minutes and did superbly to parry clear Kavanagh's snapshot before denying Jack Stafford at the near post.
7. Joe Thomson
Beginning to hit top form and capped off an energetic performance with a sublime goal eight minutes into the second half as he cut inside on his left foot. Got himself in promising goal scoring areas on several occasions during the match.
8. Danny Lafferty
Arguably his best performance since returning to Brandywell. Deployed at wingback, Lafferty was a constant threat and attacking outlet on the left wing. His delivery from advanced positions caused havoc in the Waterford defence.
