Birmingham 0-4 Derby
Three minutes of injury time done and Derby close out a comfortable and convincing win.
The Blues gifted the Rams a couple of goals in the first half, with Krystian Bielik taking advantage of a Neil Etheridge fumble and Graeme Shinnie converting a penalty.
Colin Kazim-Richards added a third and Jason Knight completed the scoring late on.
It's just one defeat in eight games for the Rams under interim boss Wayne Rooney.
