Chesterfield moved up to sixth in League Two after a first-half goal from Sam Curtis gave them a 1-0 win against Gillingham.
The result extended the Spireites' impressive recent form to just one defeat in nine games, with the home side beginning the day outside the play-off places.
Set-Piece Settles It
Chesterfield goalkeeper Zach Hemming got down smartly to make a save from Ronan Hale at his near post before the home side scored what proved to be the winner in the 16th minute.
