Substitute David McDaid hit a second half winner as Derry City bounced back from two league defeats and their Europa League exit to Trabzonspor midweek to beat Limerick 1-0 at Thomond Park to move back up to third place in the Premier Division table.
McDaid's goal saved the blushes of team-mate Michael Rafter who had a first half penalty saved by Barry Ryan.
It was Limerick who had an early shout for a penalty waved away by referee Paul McLaughlin when Shaun Kelly appeared to be hauled down inside the area by Barry McNamee.
The sides then swapped good openings in quick succession ten minutes before half-time. David O'Leary fluffed a chance for Limerick just six yards out. Derry broke away immediately and Paddy Kavanagh got past Shane Tracy to cross for Ruaidhri Higgins whose bicycle kick flew wide.
Derry then blew the best opportunity of the first half on 40 minutes when awarded a penalty after Simon Madden was hauled down inside the area. But Limerick keeper Ryan saved Rafter's poor spot kick.
Limerick midfielder Joe Gamble wasted the home side's best chance on 65 minutes when somehow putting his shot over the bar from just yards out after Derry keeper Ger Doherty pushed away a header from Craig Curran.
Derry then struck for their winner five minutes later. Fellow substitute Sean Houston flicked on a long ball for McDaid to take a touch before shooting low past Ryan for a well-taken goal.
