A superb goal from Burnley's Michael Kightly in the 65th minute condemned Barnsley to defeat at Turf Moor on Saturday night.
It was caretaker Micky Mellon's second match in charge following the superb win at Brighton on Tuesday night and, despite a good first half performance, they were second best after the break. The result meant Burnley went back to the top of the Championship while the Reds are still bottom with 14 points from 19 matches.
High-flying Burnley started on top and Sam Vokes twice went close before Reds 'keeper Jack Butland palmed away a powerful long-range shot from David Jones. Danny Ings then headed wide from a fine cross by ex-Red Kieran Trippier.
Barnsley's Paddy McCourt was on top form in the first half. He set up two fine chances that Tomasz Cywka missed and went on plenty of his trademark runs.
While the Reds played well in the first half, they were dominated after the break and the Clarets deserved their lead when Kightly curled in a fine 20-yard effort after good work from Trippier.
