Jimmy Keohane emerged from the bench to net the only goal of the game as Cork City beat Sligo Rovers by one goal to nil at Turner's Cross.
Keohane netted twelve minutes from time to keep Cork to within two points of leaders Dundalk.
The Bit O'Red managed to take two wins from their last three visits to Leeside, but had to rely on their goalkeeper Mitchell Beeney to keep the champions at bay early on.
With barely two minutes on the clock, Colm Horgan managed to find what was limited space behind the Rovers rearguard before squaring for Graham Cummins, who from point blank was denied by a super stop from Beeney. The Chelsea loanee reacting quickly to get down and scoop the striker's header off his line.
Sligo slowly settled. Paddy McClean got a leg in front of Barry McNamee's shot after a well worked one-two with Cummins at the edge of the Rovers area just short of the 20th minute.
Beeney was called into action once more, six minutes from the interval, when he was forced in to diverting Karl Sheppard's bending cross over his crossbar. Ger Lyttle's charges continuing to rebuff City.
Conor McCarthy's header from a Sheppard corner whistled narrowly past the Sligo post to leave it scoreless at the break.
McNamee somehow fluffed his lines from close range after Kieran Sadlier's low cross from the left made it all the way across goal. The Donegal native only able to find the advertising hoardings from four yards out.
Cummins flashed a header past the target on 72, but the Rebels were not be denied six minutes later.
Rovers couldn't clear Horgan's cross before Keohane was allowed time to pick out the corner of the net for his first of the year.
The men from the west did muster a late chance to steal a point, but substitute Adam Morgan's volley didn't trouble McNulty three minutes from time.
