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 led 1-0 with an early 20-yard opener from John Swift, the game hinged on a 23rd-minute Blues penalty.
Albion defender Cedric Kipre was adjudged to have brought down Koji Myoshi when the Japanese appeared to slip - and Juninho Bacuna scored the resulting spot kick.
Former Wolves defender Dion Sanderson then headed a second on 38 minutes to complete the first-half turnaround.
Substitute Gary Gardner curled in a superb third from a free-kick to seal the points on 87 minutes, just five minutes after coming on.
