As he did when the sides met at the same venue in April, Conan Byrne scored twice as St Patrick's took out their FAI Cup frustrations on hapless Wexford Youths at Richmond Park.
Pat's created a host of chances before deservedly taking the lead on 20 minutes as they cruised into a 3-0 half-time lead.
Byrne and Christy Fagan were among those initial opportunities before the former made no mistake in breaking the deadlock, calmly placing the ball past Youths' goalkeeper Graham Doyle from Graham Kelly's through pass.
Frantic defending by Youths prevented a second goal on 25 minutes as Billy Dennehy's shot was blocked away after Fagan all too easily found him in space. And the chances just kept coming for the home side. Fagan shot wide on the turn on the half-hour before making amends within two minutes, finishing off a move involving Ian Birmingham and Jamie McGrath to rifle past Doyle.
Youths defender Lee Chin then brought down Kelly in conceding a penalty within a further two minutes with Byrne scoring confidently from the spot. Though Youths were better on the resumption, St Pat's soon regained control, Kelly then got Pat's fourth goal on 79 minutes, bouncing a downward header past Doyle from Bermingham's left-flank cross. A fine solo run and deflected shot from Jonny Bonner brought Youths' consolation goal four minutes later.
Meanwhile, Finn Harps claimed a valuable 2-1 win over Bray Wanderers at Finn Park, Sean Houston scoring a brace for the Donegal side, with Dean Kelly replying for Bray.
