A JON Macken goal separates the sides at half-time at Oakwell despite Burnley's dominance.
The Clarets had all the early possession with Robbie Blake and Chris Eagles forcing good saves out of Barnsley keeper Heinz Muller.
But it was the Tykes who took the lead when Macken sprung the offside trap and fired past Brian Jensen.
Moments later, Kayode Odejayi should have put the home side further in front but, this time, Jensen made the save.
Clarke Carlisle and Chris Eagles found their way into the referee's notebook before Stephen Jordan fired an effort over the bar.
