Derry City have now lost just one of their past six games.
Derry City are up to second place in the Premier Division thanks to a 2-1 win over Cork City at Turners Cross.
The hosts' manager Tim Clancy resigned after the defeat with his side second from bottom with two wins from 15 games.
Tiernan Lynch's side broke the deadlock when Liam Boyce fired home after Gavin Whyte had capitalised on a defensive mistake on 24 minutes.
Cork levelled the match through Djenairo Daniels, but Derry retook the lead with just over ten minutes to go thanks to Kevin Holt.
The result means that Tiernan Lynch's men are now unbeaten in three while Cork are without a win in four games and on the hunt for a new manager.
Former Northern Ireland international Liam Boyce was on the scoresheet for Derry
Derry dominate opening 45 minutes
Cork stopper Tein Troost was called into action just three minutes into the game and made a crucial save to stop Boyce's close-range header from giving Derry an early lead.
The host's first chance fell to Darragh Crowley with his strong shot deflected out of play and Cathal O'Sullivan's effort from the resulting corner well over the crossbar.
The away side couldn't take advantage of their first corner either with Carl Winchester also firing well off target.
Derry did take the lead shortly after though when Troost rushed off his line to try and gather a long delivery but Gavin Whyte was able to control the ball and lob the stopper before finding the onrushing Boyce, who made no mistake from point blank range.
It looked like the Candystripes were going to double their lead just before the break when Sam Todd headed Michael Duffy's right-footed corner towards goal. However, Daniels headed the ball to safety.
Candystripes grab late winner
Just after the restart Ronan Boyce nodded Michael Duffy's looping cross into the back of the net, but Boyce had strayed offside so the effort didn't stand.
Milan Mbeng then sent a shot off target before Troost was called into action to gather Whyte's cross which was heading for Duffy.
Brian Maher, who had a quiet first half, then thwarted Cathal O'Sullivan's shot from a tight angle after some good work from the winger.
Cork's persistence paid off and they levelled the game in the 62nd minute after a quick throw-in released them down the left wing with the alert Daniels able to convert Kitt Nelson's cross.
The home side looked to complete the comeback but Rio Shipston's free-kick was headed wide of the left-hand post by Charlie Lyons.
At the other end, the busy Troost palmed Duffy's free-kick away before Todd's header from the resulting corner was cleared off the line by Shipston.
There would be another goal before the full-time whistle and it came for the away side on 78 minutes when substitute Holt nodded a corner home for his first goal in a red and white shirt.
Despite 10 minutes of additional time Cork couldn't find a second leveller.
