Two first-half goals from Emil Riis gave the Lilywhites their victory, the Danish striker's opening goal a bit special.
There were several strong performances in the North End team, Riis, Ali McCann and Tom Barkhuizen among those to shine.
Daniel Iversen also made a stunning late save from a deflected shot to ensure a clean sheet.
Here are the PNE player ratings from the 2-0 victory.

3. Patrick Bauer 7
A typical no-nonsense from the centre-half and only a good save in the opposite penalty box prevented him getting on the scoresheet. Photo: Rich Linley/Camerasport
4. Andrew Hughes 7
The Welshman was very steady on the left side of the back three, clearing his lines and defending the box well. Photo: Rich Linley/Camerasport
