Birmingham City had to come from behind to beat Sunderland as they won successive Championship games for the first time since October.
After trailing to a sloppy Jack Clarke goal at half-time, Blues turned it round with a Jordan James equaliser before Koji Miyoshi struck an 80th-minute close-range winner.
Roared on by a crowd of 27,449 - the biggest home gate for more than seven years - that completed a double for Blues boss Tony Mowbray, who won this fixture when still the Sunderland manager back in November.
Having led the Wearsiders to a 3-1 win at the Stadium of Light he repeated that trick in his first meeting against his old club.
