The Glens start brightly and almost take an early lead when Michael Halliday headed wide.

But the deadlock was broken on 29 minutes when Aidan O'Keefe fired into the right hand corner of Elliott Morris' goal after finding space on the left.

Glentoran then suffered a further setback on 37 minutes when they were reduced to ten men when Jason Hill was sent off for bringing down Eamon Zayed as he bore down on goal.

And, one minute from the break, it got even worse when the Drogs doubled their advantage after Tony Grant found space between Paul Leeman and Gary Smyth to beat Morris.
