Greg Cunningham and Ryan Ledson after PNE's goalless draw at Stoke City
It was a much-needed clean sheet after the 5-0 drubbing by Brentford a week earlier, their defending having to be good in the first half when hosts Stoke were on top.
The Lilywhites are now in 17th place but 10 points clear of Rotherham who are 22nd in the division.
Here are the player ratings for the North End side.
The goalkeeper made first-half saves from Tymon, Powell and his team-mate Whiteman. Safe handling and vocal in the penalty area. Played in the three-man central defence and looked at home in his natural position. Defended well and had a decent battle against Norton. Had the central role in the back three and didn't look comfortable. His passing from the back was hesitant and his misjudgement at the end almost let in Jacob Brown. Strong on the left side of PNE's defence and made some good clearances and blocks in the first half. At the other end he saw a free-kick hit the post. Looked more comfortable at right wing-back than he had done on the left in the last couple of games. Came more into the game as an attacking outlet in the second half. In a creative sense wasn't involved a great deal but he did a key job keeping a close watch on Stoke's attacking midfielder Nick Powell. Better in the second half as PNE emerged as an attacking unit. Had a couple of shots and was on set-piece duty. Off the boil first half but had far more of an influence in the second half. Was brought down by Souttar for the red card but wasted a great late shooting chance. Solid enough at left wing-back on his return to the side after injury, better going forward in the second half. Got little service in the first half and ended-up chasing balls down the channel. Better in the second half but put a header from six yards too high. Struggled to make an impact up front, especially in the first half. A willing runner but needs to be in the box more. Joined the action as part of a double substitution, playing up front. Worked hard but upset Stoke with a challenge on Nick Powell. Came off the bench and made an impact, set up Browne for the run on goal ewhich led to Souttar's red card for Stoke.
