Ace marksman James Dean booked Chorley’s place in the third qualifying round of the FA Cup but they were made to sweat for it.
Inspired by a noisy away following, North End belied the 67 places separating these two sides in the football pyramid by frustrating Garry Flitcroft’s high-flying Magpies.
But the plucky North West Counties League visitors were finally seen off in the 72nd minute when Dean struck in typically predatory fashion.
There were few signs of the difficulties to follow as Chorley made a blistering start which could have produced two goals inside the opening 90 seconds.
Josh Hine’s venomous cross-shot snaked inches wide of the far post and a rasping Dean volley suffered a similar fate with keeper Gregory Hall rooted to the spot.
But that was as good as it got for the Magpies in an error-strewn first half as they struggled to break down an uncompromising North End defence.
The introductions of substitutes Jack Dorney, Paul Jarvis and Astley Mulholland belatedly injected some much-needed creativity in the final third.
With North End starting to dream of a money-spinning replay, the deadlock was finally broken with 18 minutes remaining. Dean rose to meet Adam Mather’s teasing free kick and his downward header spun off the turf and looped over keeper Hall.
North End’s only chance of note was a Samuel Hare free kick that flew narrowly wide, otherwise keeper Sam Ashton was largely redundant.
The visitors finished the game with 10 men when Edward Moran saw red for pulling back Mulholland in injury time.
Chorley: Ashton, Ross, Mather, Doyle, Smyth, Roscoe, Hine (Mulholland, 68), Whitham, Dean, Lynch (Dorney, 53), Stephenson (Jarvis, 53). Subs not used: Teague, Almond, Esdaille-Biney, Grundy Attendance: 675.
Elsewhere in the FA Cup second round of qualifying, Andy Bell’s late penalty handed Bamber Bridge a 1-0 win at Workington while Billy Askrigg’s late winner gave Lancaster City vctory by the same scoreline at FC United.
