Chesterfield slipped to a third consecutive defeat in the space of a week, this time at home to Swindon Town on Tuesday night.
A thunderous Yaser Kasim free-kick and Nathan Byrne’s powerful drive had put the Robins ahead at the break at the Proact Stadium.
Jon Obika missed two glorious chances for Swindon before his replacement Andy Williams got a bit of luck and tapped in to an open net.
It is now one win in nine for the Spireites who will hope for a return to winning ways on Saturday when they face struggling Yeovil Town.
Chesterfield looked to make home advantage count after consecutive losses on the road but suffered their worst defeat of the season.
The visitors to a rain-soaked Proact, Swindon, were on a similar run of form to the Spireites prior to kick-off and had first sight of goal but Louis Thompson couldn’t keep his effort down from the edge of the box.
Chesterfield responded immediately with Dan Jones firing a cross-come-shot in to a crowded penalty area that found Dan Gardner at the back post who fired wide of the target from an angle.
It promised to be an end-to-end encounter and so it proved, if the first ten minutes were anything to go by. Thompson had another chance to test Tommy Lee, in the hosts’ goal, but sliced wide.
The Spireites set off on another attack and when Jones swung in a cross from the left, Jimmy Ryan stuck out a leg to direct the ball towards goal with the ball narrowly missing the angle of post and bar.
Gardner had been a livewire in the opening exchanges from the left, switching sides with Sam Clucas, and came within inches of opening the scoring with a curling effort that had Swindon keeper Wes Foderingham watching on.
Gardner, cutting in from the left touchline, found Eoin Doyle, who beat one and unleashed a powerful drive that Nathan Thompson blocked on the slide. Clucas nipped inside Amari Bell but shot straight at Foderingham.
Jon Obika was guilty of missing a glorious chance when he skipped round Lee and, with the goal gaping, put the ball wide of the target as Tendayi Darikwa attempted to block on the slide.
Ryan’s volley didn’t have enough dip on it from the edge of the box after he had been set up by Gardner. More patient play saw Ryan set up Sam Morsy who brought a superb reaction save out of Foderingham diving low to his right.
Swindon looked threatening on the break and, after Kasim had come close with one free-kick, he went one better moments later from even further out. His swerving powerdriver beating the attentions of Lee.
Spireites skipper Ian Evatt was cautioned in the foul that led to the free-kick and will miss Saturday’s home match against Yeovil Town with a fifth booking of the season.
Chesterfield barely had time to reassess before Swindon were on the attack again. Byrne cut inside from the right and got away from Jones before he unleashed an unstoppable effort beyond Lee.
The home side were getting some joy down the left and Jones’ cross was just too far for Doyle to get something on. He found the Irishman moments later from a similar position and the striker headed over.
Massimo Luongo chested and volleyed a shot just wide of Lee’s left hand post with the Chesterfield keeper diving at full stretch to his left, as the rain began to lash down at the Proact.
A double switch by Cook five minutes in to the second half saw Gboly Ariyibi and Dan Johnson replace Gardner and Ryan. Clucas headed straight at Foderingham from a left win cross.
Obika tried to make amends for his earlier miss when he slid in at full stretch in attempt to divert Michael Smith’s driven effort that had skipped off the surface in to an unguarded net.
Smith had a more clear cut opportunity moments later when Obika slid him in with Lee to beat only for the Spireites keeper to make a vital stop with his feet. Obika couldn’t follow up for Swindon and the danger was cleared.
Chesterfield prodded a probed but couldn’t find a way through. Swindon, however, continued to break at speed and Obika should have scored when he planted a header against the foot of the post from two yards out.
His replacement, Williams, scored with one of his first touches of the ball when Byrne, on another twisting run from half-way, had played him in. Georg Margreitter and Lee did their best to block but the ball rebounded kindly for the substitute who rolled it in for number three.
Byrne looked to have the beating of the Spireites defence and set up Smith to fire at goal, the striker’s effort not missing the target by much. Williams was faced with another one-on-one only to loft the ball over, as the visitors saw the game out.
