Barry Corr's goal isn't enough as Blues suffer their first defeat of 2015.
Southend United failed in their attempts to register their second win in a week, after suffering a narrow 2-1 home defeat to Accrington Stanley.
Second half goals from Piero Mingoia and Terry Gornell sealed the victory for the Lancastrians, with Barry Corr's goal giving Blues hope in the final 20 minutes, but it wasn't enough.
There was big team news prior to kick off, with Dan Bentley picking up an injury. This meant a professional debut for highly rated goalkeeper Ted Smith.
It was a patient start from the hosts, who restricted the visitors to not having a shot before the half hour mark. The best opportunity during this time fell to Joe Pigott.
The in form forward – who bagged twice against Cheltenham Town earlier in the week – latched on to Rob Atkinson's poor back pass, and although his dinked effort beat Accrington 'keeper Scott Davies, it skimmed the crossbar before going out for a goal kick.
On 32 minutes, a neat corner from Josh Windass found Stanley skipper Luke Joyce at the near post, and his flick on was headed off the line by Ryan Leonard.
After the break, Accrington took the lead through Mingoia's volley from inside the box, after a ball in wasn't cleared correctly.
Instantly, Phil Brown made a change, with David Worrall returning from his lay-off to replace Will Atkinson.
Moments later, and Accrington came close to doubling their lead, with Joyce heading over the bar from a left-wing cross.
Blues responded after the hour mark, and a delightful cross from Jerome Binnom-Williams found his defensive partner Adam Thompson, but Thompson flashed his header just wide of Davies' left-hand post.
Stanley did double their lead with 20 minutes of the game remaining. After being put through on goal, Gornell chipped the ball over the on-rushing Smith and into the net.
But Blues were back in the game almost immediately, as substitute Corr headed home from close range following a deep cross from Worrall.
Brown threw caution to the wind late on, with Corr, Kevan Hurst, Worrall, Pigott and Jack Payne all on the pitch for the final 20 minutes, but the Accrington backline stood strong, as Blues suffered their first defeat of 2015.
