Birmingham created a piece of club history but Cameron Jerome's failings in front of goal meant they had to settle for a goalless draw against Wigan at St Andrew's.
And an afternoon of frustration for Blues was compounded when top scorer Craig Gardner was given a straight red card for a lunge at Franco Di Santo in the last minute.
Alex McLeish's side equalled their best top-flight unbeaten home run of 18 games stretching back exactly 12 months. But Jerome missed two golden first-half chances to earn his side all three points.
