Akwasi Asante opened the scoring at the end of the first-half but a ruthless display after the break saw him claim the match ball and help to ensure Peter Beadle’s Barnet were subject to a crushing 6-0 defeat.
James Rowe made two changes to the side that were victorious over Sutton in midweek. Scott Boden came into the side to replace Tom Denton and Josef Yaney came in to replace Will Evans who is serving a one match ban for picking up his fifth yellow card of the season season.
Chesterfield should have taken the lead inside the opening five minutes when Joel Taylor delivered a teasing ball towards the back post but Scott Boden failed to direct it into the back of the net.
A few minutes later Tom Whelan flicked the ball over some orange shirts looking for Asante but Jerome Binnom-Williams got there first to chest back to Scott Loache in the Barnet goal.
James Rowe’s side looked dangerous again when Tom Whelan looked to be through on goal but Binnom-Williams dispossessed him to deny his former club a goalscoring opportunity.
The Bees struggled to create clear-cut chances but looked a danger in the wide areas.
Mahammadu Faal came closest when Haydn Hollis' Clarence deflected off Laurence Maguire and into the path of the forward who drove towards goal but his resulting effort whistled past the post.
In the 34th minute Asante only had Loache to beat from close range but the striker couldn’t find the target.
However he made no mistake five minutes later when Jak McCourt played a sublime through ball to the striker who slotted past the Bees ‘keeper to put the Spireites ahead going into the break.
The home side doubled their lead not long into the second-half when Jak McCourt delivered a 50-yarder up to Joel Taylor who brought the ball down well off his chest and delivered to Boden who converted; smashing the ball into the back of the net.
McCourt played a key part in the third goal too, his corner was placed perfectly for centre-half Haydn Hollis to turn in at the near post and score his second goal in two games.
With fifteen minutes remaining the deficit increased from three to four. McCourt intercepted a Barnet pass to spark the attack, finding Whelan who gave the ball to Asante allowing the striker to dispatch into the bottom corner.
Asante bagged his hat-trick soon after when a long ball looked to be going out of play, but he brought it down and controlled the ball to bring it towards goal, twisting and turning past orange shirts to fire home.
Despite Kyle Letheren not having the busiest of afternoons, the Spireites 'keeper pulled off a magnificent double-save in the 84th minute to keep the ball out of the back of the net and keep his third consecutive clean sheet.
McCourt got his name on the scoresheet in the final minutes to make it six. Substitute Liam Mandeville dinked the ball to the far post allowing McCourt to bundle it over the line following a remarkable charge towards goal.
An incredible 6-0 win over Barnet saw James Rowe continue his unbeaten run in charge at Chesterfield and as a manager this season. The Spireites are back in League action next Tuesday when they face a long away trip to Dover but are in action in the FA Trophy on Saturday, at home to either Brackley Town or Royston.
