Cork City must travel to Linfield for their Setanta Cup semi-final after the Blues beat Glentoran at the Oval to finish top of Group One.
The visitors took the lead after just seven minutes when Thomas Stewart's sweet left-footed effort beat goalkeeper Elliott Morris.
However, Glentoran levelled three minutes before the break when Kyle Neill fired home from the penalty spot after Kris Lindsay was adjudged to have brought down Chris Morgan in the area.
Linfield's Peter Thompson then struck on 55 minutes after breaking clear of the defence and slotting the ball through Morris' legs to claim victory.
