Reserve team defender Charlie Lee and Chris Riley returned from injury as the lads performed well but were thwarted on numerous occasions by the Birmingham goalkeeper and when he was beaten, Matthew Wells (pictured right) saw an effort come back off the woodwork.
The home side took the points with goals after 15 and 85 minutes.
Here is coach Pat's rundown. "We couldn't have started the game any brighter and in the first five minutes we were through on the goalkeeper on two occasions.
"They were great chances, one-on-one inside the penalty area and the keeper has made two saves.
"After 15 minutes we were hit on a set-piece, a free header and we were 1-0 down.
"Ten minutes later and Matty Wells hit a 20-yarder that the keeper got the slightest of touches to and it hit the underside of the crossbar and bounced out. Terry Dixon then had a free header from a set-piece and missed the target.
"At half-time we told the lads to keep going but the game started to level off and we started to lose confidence and they scored with about five minutes to go."
