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.
13. Darren Cole
Once again the introduction of Cole off the bench shows the strength in depth in Higgins' side. Replaced debutant Evan McLaughlin to shore up the Derry midfield on 72 minutes as the Candy Stripes held on to their 2-0 advantage.
14. Jack Malone
Lost his place in the starting line-up as Higgins opted for two wingbacks and Harkin and Thomson in central midfield. Introduced for the final six minutes and made a decent impact, forcing a save from Brian Murphy late on.
15. Will Fitzgerald
Replaced Akintunde with 18 minutes to go. Not a bad option, however, to bring off the bench. Entered the fray at a stage when the match appeared comfortably won and as Waterford pressed. Didn't see as much of the ball as he would've liked.
