Barnsley suffered back to back defeats for the first time this season and the first time since April.
It is the first time it has occurred for Barnsley in League One since the horrendous run of eight straight defeats between October and November 2015 - Barnsley have played 44 League One games (including playoffs) in between.
The wheels were set in motion for this defeat with a goal after just two minutes - the earliest Barnsley have conceded since Daniel Ayala scored after just one minute for Middlesbrough in March.
Coupled with Karlan Grant's eighth minute goal for Charlton at the weekend, Barnsley have conceded in the opening 10 minutes of a match in successive games for the first time since October/November 2015 when they conceded after six minutes at Scunthorpe and then after three minutes at Coventry.
They have now conceded three times in the opening ten minutes this season (also at Scunthorpe - ninth minute)
Barnsley were 2-0 down at half time for the first time since the 24th April at Nottingham Forest and the first time at this level since the 3rd November 2015 when they were 2-0 down at Coventry.
They went on to concede three goals at this level for the first time since the 24th November 2015 at Peterborough.
Ethan Pinnock had given the Reds hope by pulling the score back to 2-1 after 49 minutes - his third goal for the Reds with those games finishing in one win, one draw and now one defeat.
Goals were scored in the first five minutes of both halves of a Barnsley game for the first time since the 15th August 2017 against Nottingham Forest (3minutes and 50minutes)
This was the first league game this season in which Barnsley have lost when they have scored - the longest they have gone into a season with such a record since 1982-1983 when each of their first four defeats arose without scoring, their fifth was 2-3 in December 1982.
This was Barnsley's first Tuesday night League One defeat of the season (from three such matches) and their first in eight at this level W5 D2 L1
Barnsley have now lost six of their last nine visits to Shrewsbury.
However overall this was only the second defeat in eight meetings.
Barnsley have conceded a goal in both halves of a league game for the fourth time this season - Scunthorpe, Luton, Charlton, Shrewsbury.
Just three games ago Barnsley had the best goal-difference in the league by +5, now they have fallen to second in that list with Sunderland now ahead by 1.
Since making a record breaking start to the season of four successive clean sheets, Barnsley have kept only one shutout in the subsequent ten, conceding 14 times in that run.
Barnsley enjoyed 53% ball possession, only at Bradford (49%) have they failed to have more ball possession than their opponents this season.
Barnsley had only five shots in the game, their lowest amount of the season and indeed the first time they have not managed double figures.
Only two of those shots were on target, their lowest amount on the road this season.

Shrewsbury manager John Askey said:
It was probably our best performance,”
“I thought the work rate was what we are after.
“That gave us a platform to play as well as we did. We came in at half-time thinking we should have scored more goals really – that was the only disappointment.
“It’s what I needed and what the club needed – you can’t ask the players for any more than that.
“They’re a good team, they have done really well until Saturday and today. They’ll be up there come the end of the season.
“If we can compete against teams like that – then there is no reason why we cant start looking to progress up the table."
