Cork City 0 Bohemians 1
Glen Crowe scored a sublime late winner to move Bohemians seven points clear at the top of the table with a game in hand.
Pat Fenlon's side are now unbeaten in 19 league games and looking like real champions despite a third of the season still remaining.
A dogged Bohs defence, which had conceded just one goal in their previous eight games, frustrated Cork in the first half.
Cork had all the possession and six corners, but really only threatened Brian Murphy on one occasion when Brian Mooney got in only to shoot wide.
Bohs then struck for the winner 76 minutes. Crowe got free on the left and brilliantly beat Mick Devine with a stunning left-foot strike.
