Poya Asbaghi's wait for a first win as Barnsley boss is now the longest of any head coach or manager in half a century after Barnsley lost 2-1 at high-flying Blackburn Rovers on Wednesday evening.
The hosts took the lead midway through the first half which they dominated but Carlton Morris levelled on the stroke of half-time totally against the run of play.
The lead was restored midway through the second half and recorded a sixth straight win which keeps them third.
Second-bottom Barnsley are winless in eight and seven points adrift of safety while several sides above them now have at least one game in hand.
The Reds have not won any of their first 12 away games for the first time since 2001/02 when they were relegated to the third tier.
Asbaghi is now the first head coach or manager not to win their first six games in charge of Barnsley since John McSeveney in 1971/72.
He made two changes from the team that drew 0-0 at home to West Bromwich Albion 12 days earlier.
Romal Palmer, who returned from illness, replaced Claudio Gomes and Clarke Oduor came in for Jordan Williams. Cauley Woodrow was still out with a knee problem.
Barnsley played 4-2-3-1 with Callum Brittain at right-back and Liam Kitching left-back while, from right to left, Oduor, Callum Styles and Morris, were behind lone striker Aaron Leya Iseka.
The hosts dominated the first half and should have been far more than 1-0 up, as Barnsley's defence was opened up time and time again by clever balls through or over them while there was very little protection from central midfielders Josh Benson and Palmer.
Blackburn had the ball in the net after 58 seconds when Reda Khadra was put clean through by a long pass and got ahead of Kitching then fired past Collins but the referee had stopped the game due to a head injury to Benson.
But Barnsley then had a decent spell and had their first shot in the 15th minute. A good Benson pass out to the right found Brittain who played it onto Styles whose 22-yard effort was pushed away by goalkeeper Thomas Kaminski diving full-length to his right.
Three minutes later, former Barnsley loanee Joe Rothwell burst very easily through the visiting defence into the left of the box and shot across Brad Collins but it hit the inside of the right post and bounced out. That began a period of total Blackburn domination as Barnsley were incredibly porous in midfield and defence while barely attacking.
Blackburn top-scorer Ben Brereton shot over from 25 yards after collecting a long ball then, minutes later, John Buckley fired narrowly wide of the bottom right corner from slightly closer after a mix-up between Benson and Iseka.
The goal arrived on 24 minutes when Palmer lost the ball deep in his half and Buckley played through Rothwell who found the bottom right corner.
Ryan Nyambe then fired just wide of the top left corner from 15 yards.
Blackburn missed an almost unbelievable chance to double their lead on 37 minutes when Khadra's pass meant Buckley and Brereton-Diaz were both clean through with only Collins to beat. Buckley squared the ball past the goalkeeper but Styles got back to make a fantastic goal-saving tackle.
Two minutes later, Brereton cut in from the left of the box and his powerful shot was pushed away by Collins.
Morris' equaliser came after a scramble in the box then the shot took a deflection before hitting the right post, rolling across the line and hitting the other post before creeping in.
The second half was more even and quiet but Blackburn always looked the more threatening side.
Michal Helik came off just after the hour-mark after receiving treatment for an injury, and was replaced by Jasper Moon.
Within minutes, the hosts retook the lead. Styles tried to lead a counter-attack but was dispossessed in his half and Buckley found Brereton on the left then he cut inside and provided a superb finish into the bottom right corner.
Barnsley barely threatened an equaliser with Palmer miskicking when 15 yards out after a corner then a Styles shot from 20 yards which went over in injury-time.
Home substitute Sam Gallagher drew a save from Collins on the edge of the box after a dreadful Benson pass then Brereton-Diaz was put clean through by a defenders' header but blazed badly wide eight yards out on the left of the box
