The Reds score four times on the road for the first time since December (4-3 win at Cardiff)
Lloyd Isgrove scored Barnsley's first ever goal at Burton Albion and Matthew Lund's equaliser was the first home goal Burton have ever scored against Barnsley.
It is the most goals ever in a Barnsley v Burton fixture, surpassing the five scored in their very first meeting, a 5-0 FA Cup win for Barnsley in 2014.
It also means Isgrove has scored in his last two starts for The Reds, the other one being that famous header at Wembley to seal promotion to the Championship.
Four goals were scored in the first half of a Barnsley game for the first time since December 2016 when The Reds led 3-1 at half-time at Cardiff, eventually winning 4-3.
Burton who had failed to score at all in five of their previous six league matches netted twice for the first time since the 16th September (2-1 home win v Fulham)
It was the first time the Brewers had netted two first half league goals since the 18th March when they scored three before the break in a 5-3 defeat to Brentford.
All four goals in the first half were scored with the only four shots on target in that opening 45 minutes.
Lloyd Dyer's 45+3 minute effort was the latest Barnsley have conceded in the first half this season. beating Lee Gregory's 45+2 goal for Millwall.
Adam Davies has now gone 11 away games since keeping a clean sheet (all comps)- it is Barnsley's longest run without an away shut out (all comps) since 2015 (20 matches)
Barnsley scored at least three times on the road for the second time this season and the second time in their past three away games.
They are unbeaten on the road in three - their best run since January/February.
This was Barnsley's second win in their last 10 away league matches- home and away it was only their fifth win in 19 league outings.
It is the first time they have gone successive away games unbeaten since February (0-0 at Reading, 3-1 at Aston Villa)
Overall though The Reds have lost only one of their last six matches.
It is the first time Barnsley have scored at least three times and a striker not get one of the goals since the 3rd November 2015 when Alfie Mawson and Josh Scowen (2) netted in a 4-3 defeat at Coventry. Since then The Reds have scored at least three times on 22 occasions with a striker at least netting once.
If you class Craig Hignett as a midfielder and not a sriker this is the first time Barnsley have scored as many as four in a match without a striker contributing since August 1999 when they thrashed Portsmouth 6-0 (goals from Robin Van Der Laan, Darren Barnard, Matty Appleby (2), Craig Hignett)
It is the first time there has been four different scorers for Barnsley since September last year when Conor Hourihane, Adam Hammill, Saidy Janko and Tom Bradshaw netted in a 4-0 win at Wolves.
Burton have now conceded four goals in three of their past four home games.
Paul Heckingbottom opted not to use all three subsitituions for the first time since the 15th August when they defeated Nottingham Forest 3-1 (used all three in 12 successing games in all competitions since) These are the only two occasions so far this this season that not all three changes have been made.
Adam Hammill was an unused subsititue last night, it is the first time he has not started a Championship match since the opening day of the season. It is the first time he has not made some appearance for Barnsley since the final game of last season at Newcastle.
This was only the second time Barnsley have opened the scoring on the road this season (also at Millwall) They have gone on to win in three of the last five away matches that they have scored first (L2)
It is the first time Burton have ever scored twice against Barnsley, the last meeting at Oakwell (1-1) is the only other occasion they have netted at all.
Burton have scored only nine league goals this season, only Birmingham (8) have netted less.
All nine Burton goals have been scored by nine different players.
This was Barnsley's fourth win in their past 11 fixtures on Halloween (D1 L6), their previous 31st October victory was in 2009 when Daniel Bogdanovic and Jon Macken secured a 2-1 win at Peterborough.
Despite scoring four away goals for the first time this season, their total of 10 shots was Barnsley's joint lowest on the road in 2017-2018. However their six on target has only been bettered once -on the other occasion they won, at Millwall (9)
That Millwall game was also the only other occasion away this season they have had more shots on target than their opponents (last night 6-4, Millwall 9-6)
George Moncur (for McGeehan 67)
Tom Bradshaw (for Ugbo 67)
Jack Walton, Matty Pearson, Jared Bird, Mamadou Thiam, Adam Hammill.
