Cork City 4 Waterford United 0: Striker Denis Behan grabbed a hat-trick to book his side's place in the FAI Cup semi-final as Cork City put Waterford United to the sword at the second attempt this evening.

Behan,  whose goal at the RSC on Saturday ensured a Turner's Cross replay, had the home fans on their feet after just 11 minutes before doubling his tally in the 35th.

Liam Kearney grabbed a third just after the hour for the Leesiders, but it was Behan who stole the show with a third six minutes from time.

Cork join UCD, Longford Town and Bohemians in the semi-finals.
