A 5-1 first leg result was more than enough to send Trevor Croly's side into the last four, where they meet Stephen Kenny's Dundalk
The first half was an exciting affair, with both sides having chances, even if the Hoops enjoyed the majority of them. The first opportunity came after seven minutes when Karl Sheppard headed an outstanding cross from Eamon Zayed straight at in form keeper Elliott Morris. Zayed then tested the keeper three more times in the opening period, each time though, Glentorans eight most capped player was equal to it.
Glens had their own chances though and through a Jordan Stewart effort they may well have went in front had it not been for Barry Murphy’s unwavering reflexes.
The second period was not as fluid as its predecessor. The first half an hour of it was contested mainly in the middle of the field with Glentoran just about winning the exchanges in the scrap for supremacy.
That may have all changed 10 minutes from time. Dean Kelly raced onto a Robert Bayly pass and attempted to flick the ball past Morris but the experienced keeper saved well once more.
In truth, neither side really deserved the win and Glentoran will be happy to have restored some pride following the first leg drubbing, while Shamrock Rovers now advance to take on Dundalk in the last four.
