A second-half strike from Yaser Kasim was the difference as Chesterfield fell to a 1-0 defeat and gained no survival points at the County Ground.
The hosts started off brightly creating a chance within the first minute of the game. A well worked move, started off by Kasim ended up at Raphael Rossie-Branco’s feet but the defender hit his effort just wide.
It didn’t take long for the Spireites to register their first effort on goal either. Jay O’Shea did well to intercept a loose ball, then ran at the defender but his shot was tipped over by Jake Kean in the Swindon goal.
Chesterfield were beginning to grow into the game, showing good work rate. Tricky Winger Gboly Aryibi turned his defender then beat another one in the box, but his low shot was blocked and went out for a corner.
The Robins midfield pair Kasim and James Brophy were beginning to link up well, with the latter latching onto a Kasim pass but his shot was easily saved by Tommy Lee.
However, Swindon kept pushing trying to find an early goal and it nearly came. A quick corner caught out the Chesterfield players, and louis Thompson found himself free in the box and his shot beat everyone except captain Gary Liddle who cleared off the line.
After some early pressure from Swindon, Chesterfield had a good chance of their own to open the scoring. Aryibi again was causing problems on the wing, found Lee Novak in the box and the striker attempted to flick it in with his left foot but Kean just managed to palm the ball out for a corner.
The resulting set-piece fell to Sam Hird at the back post but his powerful header could only manage to land on top of the net.
Despite the Chesterfield chances, Swindon were beginning to push even more for a goal. Ever-instrumental Kasim picked the ball up in the middle, found Jonathan Obika who laid the ball off to team mate Doughty whose thunderous shot was well saved by Lee.
After receiving treatment twice inside the first 25 minutes striker Novak was substituted for Jamal Campbell-Ryce.
The chances kept coming for the hosts. A Doughty free-kick was met by Jordan Turnbull but his header went well wide of the goal.
Swindon were dominating the game and Nicky Ajose tried to have his say on the game. The striker skipped into the box, avoided a Talbot challenge but Lee did well to save at the front post.
Six minutes were added on at the end of the first half due to a number of players receiving treatment, and both teams could only manage half attempts at goal. The first came to Chesterfield as another Jay O’Shea corner fell to centre-back Tom Anderson and his volley was blocked straight into Kean’s hands.
Swindon had the last say of the first half, Thompson picked the ball up outside the Chesterfield area but blasted his shot well wide.
Like the first half, Swindon started the second well giving Chesterfield no time to settle. Brophy who was looking bright saw his shot vitally blocked by Anderson, denying him the opening goal.
With 52 minutes on the clock Swindon had their best chance to score. After the Spireites were searching for a goal the home side burst forward on the counter attack, and Doughty curled a shot which hit the inside of the post and somehow avoided the back of the net.
With the warning signs appearing for the Spireites they started getting into the game. A quick succession of corners saw the second corner causing problems, Hird on the edge of the box was about to shoot but Turnbull managed to get a foot on the ball to deny any attempt for Chesterfield.
After a lively start to the second half with Swindon creating a number of chances, the game began to settle down. Defender Rossi-Branco went in search of an opening goal and won a dangerous freekick on the edge of the Chesterfield box which was taken by Doughty but his attempt went just wide.
Doughty was causing problems for Chesterfield all afternoon, he picked up the ball after another well worked move by Swindon and his curling effort was well caught by Lee.
The midfielder was soon at it again. A quick corner from Swindon landed to Doughty and his attempt was blocked out of play, the referee awardig a goal kick to the frustration of the home fans.
With 15 minutes left Swindon again were causing problems. A Doughty shot was spilled from Lee's grasp and Obika had the goal gaping but somehow skied his effort over the bar.
After all the pressure from the hosts they finally got their reward. A one-two between Doughty and Kasim ended with the latter curling his effort into the back of the net with Lee having no chance.
Chesterfield were struggling to reply. Liddle made a crunching tackle in the middle of the park and Campbell-Ryce began a Chesterfield attack finding Talbot on the left but his cross was collected by Kean.
After the Swindon goal neither team were creating clear cut chances. The Spireites were keeping the ball well but were struggling to do anything with it.

Campbell-Ryce was doing all he could to try and find an equaliser for Chesterfield and burst into the box, crossed it but the ball evaded everyone and Swindon cleared.
