Goals from Michael Nwanko and John O'Flynn helped Cork City bounce back from the defeat to Waterford United earlier in the week against St Patrick's Athletic, who turned in their third disappointing display in seven days at Richmond Park on Friday night.
While Cork can look back with satisfaction on a productive return trip to Richmond - they had come out on the wrong end of a 2-0 result when taking on Shamrock Rovers here two weeks ago - the Saints will be licking their wounds this morning.
Having take just a point from three games over the past week, Eamonn Collins's side have dropped to seventh in the table, fully eight points behind leaders Shelbourne and just four points above detached bottom side Dublin City.
Cork, though, have found the thread once more, and with leaders Shelbourne to visit Turners Cross on Easter Monday night, this could prove to be a crucial four-day period in the Leesiders' season.
After a goalless first 45 minutes, in which Paul Rose squandered the Saints' best opportunity and John O'Flynn failed with an audacious attempt to chip Chris Adamson from 40 yards, the visitors opened the scoring eight minutes into the second half through midfielder Nwanko, the young Nigerian firing past Adamson for the opener.
While Cork had played some exquisite football, their defending again left much to be desired, a point which had been countenanced earlier in the week by their manager, the former Saints boss Pat Dolan. Dan Murray and the recalled Alan Bennett had their fair share of worrisome moments, although the latter did well to deny Rose after the striker tried to take the ball around Devine for the best chance of the opening half.
Nevertheless, it was the shaky visitors who closed out the clean sheet%
