Cork City, last year's beaten finalists, booked their place in the Setanta Sports Cup semi-finals, with a 7-0 rout of Portadown at Shamrock Park.
Two goals in three minutes from Denis Behan and John O'Flynn set the ball rolling for the eircom League side as they adopted a 4-3-3 formation for the first time all season.
Cork were forced to play this system with seven first-team players ruled out of the tie including FIFA victims Colin Healy and Gareth Farrelly and it mattered little that they only had three men on the bench.
Behan who has a knack of scoring in this cross-border series gave Cork the lead on 15 minutes and, three minutes later, John O'Flynn netted with a low diagonal drive.
Joe Gamble burst through to take O'Flynn's return pass in his stride to shoot past the ageing Pressman after Michael Collins had lost the ball in midfield.
Then just on half-time, Roy O'Donovan got in on the scoring when he bagged the best goal of the night.
Darragh Ryan's hooked pass caught the Ports defence standing square and O'Donovan ran on to score with a right-footed drive into the far top corner of Pressman's net.
The ex-Sheffield Wednesday and England 'B' keeper saved twice from O'Donovan early in the second half as Cork continued their search for more goals giving a sparse crowd great value for money.
O'Donovan made it five after he cut out a Philip Craig back pass on 66 minutes to slip the ball past Pressman again, Behan made it six with eight minutes to go before O'Donovan notched his hat-trick on 87 minutes.
