St Patrick's Athletic 0 Bohemians 1
Darren Mansaram proved the bane of St Pat's for the second time in a fortnight with the only goal at Richmond Park.
Having scored both goals to put them out of the cup recently, Mansaram scored the only goal of the game on 65 minutes, latching onto Stephen O'Donnell's clever through ball to shoot home.
Brilliant goalkeeping at both ends provided the highlights of the first half.
Bohs keeper Brian Murphy was first into action on 15 minutes when he dived to his left to push away Anto Murphy's header.
Michael McGinlay then looked set to put Bohs in front two minutes before the break, but Barry Ryan made an equally good save.
