Brilliant Barnsley crush Blues
An early goal from Barnsley striker Neil Shipperley and two second-half strikes from Bruce Dyer gave the Tykes a great chance of winning a Wembley date for the first time in their history.
The low drive from Shipperley stunned Birmingham keeper Thomas Myhre on 12 minutes and for the rest of the first-half, Birmingham, enjoying home advantage, were the more adventurous of the two sides.
But two goals in 12 minutes at the start of the second half for substitute Bruce Dyer put a massive dent in Birmingham's hopes of reaching the Premiership for another year.
Craig Hignett put the game - and maybe the overall result - well beyond the home side with a goal on 84 minutes.
