Jay Stansfield finally broke Town’s admirable resistance in the 58th minute but Jon Brady's men refused to be beaten and kept going, striking right at the death to stun St Andrews. Here are our player ratings from the West Midlands….
9. Liam McCarron
He spent most of his time on the pitch more as a second left-back than a winger but that was what the situation required. Tracked back and his ball-carrying helped Cobblers out of a few tight spots... 7 Photo: Pete Norton
10. Mitch Pinnock
He started the game by throwing himself at a goalbound shot inside his own box and he ended it by drilling home a 97th minute leveller. Typical of how he always gives everything to the cause. His corner was nearly turned in by McGeehan and it was his cross that led to Hondermarck's chance. Great composure and technique when the ball dropped to him at the death. A superb all-round performance... 8.5 CHRON STAR MAN Photo: Pete Norton
11. Sam Hoskins
A surprise starter given his recent absence. Given a thankless task as Town's most advanced player but he will do any job asked of him and the defensive effort started from the front. Went down with a problem in the first half and hopefully it was just tiredness that forced him off in the second half and not another injury... 7 Photo: Pete Norton
12. TJ Eyoma
Kept up the good work of those before him, which was easier said than done as Birmingham turned the screw. Won a couple of important late headers that kept it at 1-0 and meant Cobblers were still in the game when the clock ticked over to 96 minutes... 7 Photo: Pete Norton
