Birmingham kept their five-point lead over Wrexham in the League One promotion race after a 1-1 draw.
Wrexham had taken the lead at the Racecourse Ground on Thursday night, as Oli Rathbone fired them in front early on. Birmingham pegged them back soon afterwards with a goal awarded to Lyndon Dykes.
The result means Birmingham increase their lead to second-placed Wycombe to three points, with Wrexham.
Birmingham, on 57 points, also have played a game less than Wycombe (56pts) and Wrexham (52pts).
Spoils shared at the Racecourse
Wrexham struck the opener after just nine minutes. Ollie Palmer hassled Taylor Gardner-Hickman off the ball deep in Birmingham territory, and Rathbone picked it up before bending a lovely effort from outside the box into the bottom corner.
After 18 minutes Birmingham were level. A corner was swung in deep and Dykes headed it back towards goal before it struck George Dobson on its way in.
Wrexham are imperious at home this season and showed that power as they pushed for a winner in the second half.
Birmingham have goalkeeper Ryan Allsopp to thank for the point, particularly for a fine save on 64 minutes to keep out James McClean's header from a corner at the near post.
