Gavin Tomlin scored the only goal of the game to get Blues back to winning ways in League 2 as Paul Sturrock's side won 1-0 away at Chesterfield.
Tomlin, without a goal since Boxing Day, ended his drought with a lovely curling finish inside the final ten minutes to give Blues the leads.
Michael Spillane was handed his Blues debut, while Ryan Leonard also came into the starting XI. Luke Prosser and Anthony Straker were the two to drop to the bench.
Having not scored in their last three League 2 matches, Blues almost got off to the perfect start.
Ryan Cresswell headed Kevan Hurst’s cross into the path of Tomlin but Tommy Lee in the Chesterfield goal saved the striker’s snapshot brilliantly.
With Spillane sat just in front of the back four, Blues were looking organised and were limiting the home side to shots from distance – Marc Richards with the best effort from 20-yards that went just over.
Richards was the host’s liveliest player, and he was a whisker away from making it 1-0 just before half-time. His free-kick from 25-yards cannoned off the crossbar having well beaten Paul Smith.
He had another chance a minute later, again from a free-kick, but this time saw his effort parried away by Blues’ goalkeeper Smith.
Blues began brightly at the start of the second-half but the home side were first to create a real chance. A free-kick into the box was completely missed by Barry Corr and Smith had to be on hand in goal to make a point-blank save.
At the other end, Leonard’s long throws were proving tricky for Chesterfield to do with, but Cresswell fired well over from a loose ball.
Blues were starting to have more possession and joy as the game wore on and with 83 minutes on the clock, they were ahead. Michael Timlin did well to win the ball in midfield and played a teasing through ball for Tomlin.
The striker, without a goal since Boxing Day, showed no signs of a lack of confidence in front of goal to beautifully curl it past Lee and into the far corner.
There was late pressure from the hosts as substitute Conor Townsend had a volley brilliantly saved by Smith.
That was to be that, as Blues got back to winning ways in League 2.
