Birmingham City won their fourth successive West Midlands derby against West Bromwich Albion as they came from behind to beat the Baggies in controversial circumstances.
After Albion went in front with an early 20-yard opener from John Swift, the game turned on a hotly-disputed 23rd-minute Blues penalty.
Albion defender Cedric Kipre was adjudged to have brought down Koji Miyoshi when the Japanese frontman appeared to slip - and Juninho Bacuna scored the resulting spot kick.
Former Wolves defender Dion Sanderson headed a second on 38 minutes to complete the first-half turnaround.
Substitute Gary Gardner then curled in a superb third from a free-kick to seal the points on 87 minutes, only five minutes after coming on.
