ON a misty night at Rockmount a scrappy opening 20 minutes saw the sides level with a goal a piece following Cork City’s opener from Stephen Kenny on 10 minutes.
The home side levelled 10 minutes later, as a free kick into the box was headed home past Kevin Burns.
There were only a few more half chances in the first half but neither keeper was seriously threatened.
The second half saw both teams go for the win, both wanting to avoid extra time or penalties.
City had a free kick at the edge of the box and an unmarked Jamie Murphy had a free header to make it 2-1 to City.
The game was a very scrappy affair and a late tackle brought down City’s Stephen Kenny and caused a bit of handbags after which Kenny saw red and the Rockmount player walked away without a card.
Next up, a spectacular 30-yard shot dipped behind the Rockmount goalkeeper by Jason Forde to make it 3-1.
With five minutes to go Rockmount pushed forward and every time Cork went forward they kept the ball in the corners.
Rockmount did get one chance near the end on about 90 minutes with what looked like a handball and free out.
Referee Jerry Buttimer did not see it that way and the goal stood, making it 3-2 just before the final whistle.
City progress to the semi-final which will be at home to Waterford United while Fermoy will take on Limerick in the other semi.
No dates have been fixed as of yet but City have a 5pm Saturday friendly against SD Galway before the season proper starts on March 3rd v UCD at Belfield.
