Finn Harps 0
Derry City 5
The Candystripes were in control for much of the contest and were full value for their win. Over the three games, the honours were shared with both sides getting a win and the game in the Brandywell ending level.
The defeat, coupled with a win for Wexford Youths in the battle of the bottom sides against Longford Town, means that the gap between the Finn Park men and the relegation area is reduced. Harps are now five points ahead of second from bottom Wexford Youths.
Derry City were the better team in the opening half, but the two goal lead at half-time flattered them.
Both goals came from the penalty spot, the first after 18 minutes when Ciaran Coll was penalised for a hand ball.
The second came minutes from the half-time lead when Barry Molloy mistimed a sliding tackle on Lukas Schubert, who was also involved in the first penalty award.
On both occasions, Aaron McAneff was flawless from the spot, sending Richard Brush the wrong way.
Finn Harps did have a couple of chances with the best falling to Packie Mailey midway through the half but his header went wide of the post.
Any hopes of a Harps comeback were dashed early in the second half when Nathan Boyle hit Derry's third goal.
Dave Scully had a chance for Harps just after the hour mark, after being introduced minutes earlier, but his effort was saved by Doherty. Sean Houston also had a half chance close to the end.
In the final ten minutes Derry added a fourth when Lukas Schubert got past Coll and squeezed it home past Brush.
It was to get worse as substitute Keith Ward fired home a fifth before the final whistle.
Harps have no game now for two weeks. They will have Shamrock Rovers at home on Friday, 26th August.
