First-half goals from Ollie Clarke and Rory Gaffney were enough to earn Bristol Rovers a 2-1 victory over Rai Simons and his relegation-threatened Chesterfield teammates at the Memorial Stadium.
The home side went in front inside the first minute as Clarke lashed home a low left-foot shot from the edge of the box after Chesterfield failed to clear a Lee Brown cross.
Gaffney doubled the advantage in the 18th minute with a clinical low finish, having been put in on goal by good work from Luke James.
James had the chance to net his first Rovers goal late in the first half when pushed by Tom Anderson inside the box, but his penalty was too straight and impressive Chesterfield goalkeeper Thorsten Stuckmann stuck out a strong left hand to save.
The visitors improved after the break and were rewarded when Sylvan Ebanks-Blake pulled a goal back in the 85th minute with a curling right-footed effort from the left side of the box.
But Rovers were never seriously threatened and it took a fine save from Stuckmann to stop Chris Lines adding a third for Rovers in stoppage time.
Simons started the match and played 72 minutes before he was replaced.
REGGIE LAMBE
Mansfield ended their four-game goal drought with a 2-0 win over Reggie Lambe and his Carlisle teammates.
Matt Green scored the opening goal in the 63rd minute and Shaq Coulthirst sealed the points after 76 minutes.
Coulthirst forced a couple of early saves from Mark Gillespie in the Carlisle goal before Danny Rose had a goal ruled out for offside in the 35th minute.
Shaun Miller and Jamie Proctor both went close for Carlisle, while Gillespie blocked a powerful Coulthirst shot and Rose missed the target with the follow-up.
Green gave his side the lead when he cushioned home a perfect eight-yard header from Coulthirst's left-wing cross.
Coulthirst made the game safe when he arrowed a powerful low finish across the goalkeeper and inside the far post.
