Another early goal for the Hammers was not enough for them to continue their excellent away run against an inspired resilient Birmingham side.
Carlton Cole took advantage of a mistake by Pablo Ibanez after only 4 minutes to put the Hammers in front. The Hammers took the game to the Blues but could not secure a second goal to kill the game off.
On 81 minutes Chris Burke crossed in a corner for David Murphy to secure a deserved point for Birmingham just when the Hammers looked like clinging on for victory.
