Barnsley's good run was halted by a 1-0 defeat at home to Brentford on Tuesday night.
Former Reds striker Ivan Toney netted midway through the second half which the visitors dominated, but the hosts were denied what seemed a clear handball late on.
The result left Barnsley 14th in the Championship table with 16 points from 13 games, six off the top six and seven clear of the bottom three.
Barnsley matched the Bees in the first half but the visitors were on top after the break and always threatened from set pieces.
Valerien Ismael kept the team that had won the previous two games but brought young centre-back Jasper Moon onto the bench for Jordan Williams who has a slight injury.
Brentford began on top with Tariqe Fosu forcing Jack Walton to push over a powerful 25-yard effort then Rico Henry fired a low shot just wide of the bottom left corner from a similar distance.
Barnsley settled into the game and played some good football, including a move which saw a fine Alex Mowatt crossfield pass volleyed down on the right of the box by Callum Brittain to Conor Chaplin who found Matty James but the shot from just outside the box was well over. Mowatt then had Barnsley's first effort on target from the right side of the box but goalkeeper David Raya got down to his right to save.
Dominik Frieser was inches from connecting to a Brittain cross after a swift counter-attack involving another fine Mowatt pass.
Not much happened in the final 20 minutes of the first half as Brentford had 70 per cent possession before the interval but, after the first ten minutes, found the Reds very difficult to break through.
The visitors were clearly the better side in the second half, mainly threatening through set pieces. They had a succession of corners around the hour-mark, with Pontus Jansson heading one straight at Walton from eight yards out.
Eventually they made the breakthrough from a left-sided Mathias Jensen corner which was impressively headed into the bottom right corner by Toney from ten yards out midway through the second half. Toney did not score in 11 games at Oakwell while on loan from Newcastle in the 2015/16 but is one of the top-scorers in the Championship this season after Brentford bought him in a £10million deal.
It was almost 2-0 minutes later when Barnsley lost the ball deep in their half but Bryan Mbuemo blazed over from the right of the box.
Ismael made a triple change on 71 minutes with Herbie Kane, Victor Adeboyejo and Clarke Oduor coming on for James, Chaplin and Mowatt.
Barnsley seemed to be denied a clear handball when Adeboyejo brilliantly won the ball on the right and saw his cross hit the arm of Vitaly Janelt but the referee was unmoved.
Seconds later, Toney dragged a shot wide from the left of the box after a swift counter-attack. Brentford substitute Marcus Forss should have made it 2-0 in the 90th minute when he was clean through but Walton made a fine one-on-one save.
