Championship review: Derby held, Birmingham add to Sunderland woes

Birmingham hauled themselves out of the relegation zone and left Sunderland further in trouble at the wrong end of the Sky Bet Championship with a 3-1 win at St Andrew's.

David Davis put the home side ahead after 28 minutes, and it was 2-0 just before half-time when Jeremie Boga headed in from close range.
