John Sheridan made a return to Chesterfield with his current team, Plymouth Argyle, this evening- and helped himself to all three points.
The home side had started the night four points outside of the Play Off group and without a defeat in April.
But Sheridan’s men are hoveringly dangerously close to the drop zone.
The Spireites had been hoping for a repeat of the win (0-1) at Home Park, a victory based on Marc Richards’ goal.
Richards has had some injury issues, but started tonight at the Proact Stadium.
Plymouth were without winger Jason Banton after the Crystal Palace loanee was recalled by his parent club, but they had a lot of urgency about them in the early stages.
Drew Talbot set up Tendayi Darikwa to force a save by Jake Cole, for the home side.
But Reuben Reid and Conor Hourihane both had half chances too.
On 20 minutes, 19-year-old Joe Bryan scored with a blast from outside the area to the top right corner of the goal to put the visitors ahead.
Curtis Nelson added another, after good work from ex Rotherham player Guy Branston just five minutes later.
After half time, Chesterfield Bryan had another chance to get on the scoreboard but missed the target.
Branston, though, scored in his own net to reduce Chesterfield’s arrears by one, after a chance was engineered by substitute Alex Henshall, who had come on for Richard Brindley.
In the dying minutes, Talbot had a shot from deep inside the box - but it went over the bar, taking Spireites’ chances with it.
Chesterfield (4-4-1-1): Lee, Brindley, Trotman, Cooper, Townsend, Darikwa, Togwell, Randall, Talbot, O’Shea, Richards.
Subs (not used): Barrington, Clay, Gnanduillet, Henshall, Hird, Boden, Wafula.
Plymouth (4-4-2): Cole, Berry, Wotton, Branston, Bhasera, Cowan-Hall, Nelson, Hourihane, Bryan, Reid, Gurrieri. Subs (not used): Gilmartin, Charles, Blanchard, Young, Chadwick, Murray, Harvey.
