Chesterfield spun the game on its head with two goals in one minute from substitutes Nathan Tyson and Tom Whelan, after they went behind in the first half from Sonny Carey’s free-kick.
James Rowe made four changes to the side that beat Eastleigh on Good Friday. Gavin Gunning and Laurence Maguire returned from injury whilst Liam Mandeville and Adi Yussuf also came into the starting eleven.
Chesterfield could have opened the scoring in the third minute when Martin Smith’s free-kick found George Carline, who’s header went inches wide of the far post.
The Spireites were dominant in the opening 15 minutes without really troubling Theo Richardson in the King’s Lynn goal.
The home side went close in the 14th minute when Michael Gyasi steered his strike, from the edge of the area wide.
Carey forced Grant Smith into a superb save a few minutes later when he was through on goal. Smith did well to tip his shot round the post for a corner.
Akwasi Asante came inches away from getting his name on the scoresheet when his free-kick flew over the crossbar in the 26th minute.
Ian Culverhouse was forced to make a change in the 35th minute when centre-back Kyle Callan-McFadden was replaced by Simeon Jackson due to injury. This meant an adjustment to their formation, with striker Michael Gash moving to centre-half for the Linnets.
Three minutes later it was King’s Lynn who opened the scoring. Jackson looked through on goal before Gunning brought him down on the edge of the penalty area. Carey took the resulting free-kick which found its way into the bottom right corner.
Rowe made a double substitution just before the hour mark when Tyson and Whelan came on to replace Yussuf and Smith.
Their impact was instant as Chesterfield had three chances to equalise within a short space of time. First Gunning fired over before both Tyson and Maguire had opportunities.
The leveller came in the 74th minute when Carline’s cross from the right was met by Tyson who turned before firing into the top corner.
Carline was involved again when Chesterfield took the lead less than a minute later. His cross found Whelan who struck the ball into the back of the net to put his side ahead.
The home side had the opportunity to equalise deep into additional time when former Chesterfield striker Alex Kiwomya had the ball in a dangerous position however he directed his shot straight at Grant Smith who stood firm and claimed with ease.
The Spireites emerged victorious at The Walks to claim their fifth successive victory in the National League.
