Warrenpoint Town and Portadown were unable to fashion a goal in this Premiership encounter at Milltown.
Peter McMahon wasted Portadown's two best chances in the first half as he fired a sitter wide and then found the side netting when well placed.
Warrenpoint's Daniel Hughes should have scored in the second half but found the side-netting after being forced side by Ports keeper Billy Brennan.
Home keeper Jonathan Parr made a smart second-half save to deny Gary Twigg.
Parr had been fortunate in the first half as his mistake set up McMahon's glorious chance which the Portadown midfield somehow managed to fire wide.
Daniel Hughes was involved in nearly all of Warrenpoint's best attacking moments with him firing narrowly wide just before half-time.
Ports keeper Brennan was a late replacement for David Miskelly who suffered an injury in the pre-match warm-up.
