The Spireites won 2-0 at Eastleigh.
Chesterfield boosted their National League survival hopes with a 2-0 victory at Eastleigh on Saturday.
Second half goals from Tom Denton and Jonathan Smith secured victory for the Spireites down in Hampshire.
John Pemberton made three changes to his starting line-up for the trip down south, with Jamie Sharman, Tom Denton and Jordan Cropper coming into the starting eleven.
The home side began stronger than the visitors, with Shwan Jalal called into action on several occasions.
However, Chesterfield grew into the game as the half progressed, with Jordan Cropper impressing on his debut at right-back following his loan move from Burnley earlier this month.
In the 54th minute, Chesterfield's pressure paid off when Scott Boden's cross from the left-hand flank was met by the head of Denton, who made no mistake to put the visitors 1-0 up.
Jalal made three more crucial saves as the game progressed to keep Chesterfield 1-0 up, before Jonathan Smith doubled the visitors lead with ten minutes remaining.
A short corner was played to Smith on the edge of Eastleigh penalty area, and the midfielder sealed the points with a strong strike into the top corner of the net.
Speaking afterwards, Chesterfield's Caretaker Manager John Pemberton told Spireites Digital he enjoyed how hard his side worked defensively;
"I think the clean sheet's important to us as a team. The three points is vital, but the manner of it is as well.
"One of the things that has been thrown at us is that we've not been resilient enough, and we're starting to show more of that, but there's still work to be done."
"It was another tough game and they caused us problems, but we battled hard and got a little bit of luck at times."
Victory has lifted the Spireites up to 21st in the National League, with Pemberton's men only in the relegation zone on goal difference.
