Three of the four goals were scored in the first ten minutes of the match - the quickest start since two were scored in the first ten minutes of a 2-2 draw with Peterborough in 2010.
There have been six goals scored in the final ten minutes of Barnsley matches this season, and now four in the opening ten.
Remarkably ex Red loanee Ashley Fletcher scored Barnsley's first goal, heading past his own goalkeeper from Zeki Fryers corner. Since leaving Oakwell after scoring in the play-off final in 2016, Fletcher has scored only three times for his club (West Ham, Middlesbrough) so if you include his own goal yesterday, 10 of the 13 career goals he has scored have been for Barnsley.
Six of those 13 goals have come at Oakwell.
Middlesbrough are now managed by ex Barnsley player Garry Monk, he has won only one of his three games against The Reds as a manager now- a 2-1 victory for Leeds last season.
Barnsley have opened the scoring in six of their eight games at Oakwell this season (all comps) but have gone on to win only three.
Home and away Barnsley have now opened the scoring in three successive league matches, their best run since a run of five between the 8th and 29th April (v Blackburn, Wigan, Brentford, Bristol City and Burton)
It is the first time Barnsley have took the lead twice in a game and not won since a 3-2 defeat at Bristol City in April.
It means Barnsley have won only one of their last four home league matches and are three without a win at Oakwell.
In total Barnsley have gained victory in front of their own supporters just twice in 15 Championship outings (D9 L4)
The Reds have though managed to score more than once in successive game for the first time since April (two scored in a 2-0 win at Blackburn and 3-2 defeat at Wigan)
They scored two first half goals for the first time in eight matches and the third time this season (all comps)
But it is now just one clean sheet in 19 games (all comps)
Barnsley and Middlesbrough drew a meeting for the first time since 2011 (eight meetings)
it is the first stalemate at Oakwell since 1995- Barnsley had won four of the previous five home league clashes.
There has been 18 goals scored in the last four league meetings and this game was the first time in those four that neither team scored three times.
Prior to yesterday Britt Assombalonga had scored just once in 15 Football League games in October.
Also prior to the game only Preston had conceded fewer away Championship goals than Middlesbrough- this was only the second time they have conceded more than once away from the Riverside.
Matty Pearson and Joe Williams both picked up their fourth bookings of the season, one more will lead to a suspension (Jason McCarthy was already banned for this match after picking up five yellows)
Barnsley only enjoyed 33% possession in this game, their lowest amount since the 0-0 draw at Reading back in February (32%)
There were 17,163 supporters in attendance yesterday, Oakwell's biggest gate since 18,075 also witnessed a 1-1 draw- against Huddersfield in February.
Depending on what side of the fence you sit on depends whether you class Middlesbrough as being in Yorkshire, if not it is the highest Oakwell attendance for non-Yorkshire opponents since another club from the North of the country came to town - Newcastle in October 2016 when 18,597 were in attendance.
