Cork City produced a sensational second-half performance to humiliate Waterford United in their EA Sports Cup tie.

After a scoreless opening-half, the Leesiders scored seven unanswered goals in the second-half at Turners Cross to register an emphatic win.

Mark O'Sullivan scored twice for the home side, but most of the damage was done in a 10 minute spell shortly after the restart when the home side scored four times in quick succession.

In stark contrast, the other three games tonight in the EA Sports Cup all went to extra-time.

St Pat's beat Dundalk 1-0 at Oriel Park with Rory Feely notching the extra-time winner.

Galway United defeated Finn Harps 4-2, while Shelbourne prevailed 4-3 in a seven-goal thriller against Bohemians.
