A first-half own goal was enough for the Spireites to claim their second victory on the spin at Wrexham on Tuesday night.
John Sheridan made two changes to the side who ran out 3-1 winners at Fylde last week, with Gevaro and Mike Fondop coming in for Jonathan Smith and Anthony Spyrou.
The hosts forced the issue early as James Jennings dug out a floated cross to the far post from the left-hand side. The left back’s cross was met by Bobby Grant but Shwan Jalal reacted quickly to push the forward’s header over the crossbar.
Wrexham continued to keep their grip on the game as two efforts from outside the area whistled just past Jalal’s goal.
The Spireites registered their first shot on target with just under ten minutes on the clock when in-form striker Fondop got on the end of a Jay Sheridan cross. Fondop got up well but directed his header straight at Rob Lainton.
The same was said for Jason Oswell’s header just a few minutes later, as he could only head down to Spireites stopper Jalal.
With just over 20 minutes gone, Luke Summerfield stood over a free-kick from 20 yards out and curled the ball towards Jalal’s right-hand post, but was unlucky to see it drift narrowly wide.
Sheridan delivered a corner from the far side and captain Will Evans was the one to flick it on but he glanced his header wide.
Chesterfield were handed a fortunate winning goal when Michael Chambers attempted to head the ball back to his goalkeeper after a Tom Denton flick-on. His pass back wrong-footed Lainton and rolled into the back of the net (32’).
Curacao international Gevaro returned to the side after coming back from international duty and looked threatening as he made his way into the box from the left. The winger managed to poke the ball towards Fondop but the pass was just too far in front of the striker.
The final attempt on goal of the first half came from the home side as midfielder Luke Young fired a shot from distance, however, Jalal was able to watch the ball skid past his post and Chesterfield took a goal lead into the break.
The hosts looked for an equaliser early in the second half and created an opportunity for Bobby Grant as he was played in on the right. The Wrexham forward took aim but dragged his shot across goal and wide of the back post.
The next 20 minutes were one of limited chances for both sides but the Spireites should have doubled their lead when Joe Rowley whipped in a cross from the right. Evans was there to meet it but put his headed effort over from just a few yards out.
Evans had another chance from a Rowley cross once again but saw his close-range strike deflect wide.
The Spireites defence held firm as a late bombardment of Wrexham crosses came in to secure their second win in a row.
