Barnsley fell behind in the 50th minute, typically to Sam Winnall – they have now conceded 11 times between the 40th and 50th minutes this season.
It is the sixth time Winnall has scored at Oakwell this season (five for Barnsley) and the Reds have now won only one of those matches!
The Reds have now failed to score a first half goal for seven successive games- their worst run of the season and they have netted only two in their past 12 outings - both came in the same game, the 3-1 win at Aston Villa.
Barnsley have now gone eight games since tasting victory against Sheffield Wednesday- it is their second longest winless streak against the Owls- the most is nine set between 2003 and 2008.
Indeed Barnsley did the double over Wednesday in 2008-2009, those two victories are the only ones against the men from S6 in the last 19 meetings.
Angus MacDonald is the first Barnsley player to score for Barnsley plus an own goal against the same opponents since Lewin Nyatanga last season who gave Swindon a 1-0 lead but then also netted in The Reds 4-1 win.
It also means, incidentally, that MacDonald is the first player to score in both games of this fixture in the same season since Jermaine Johnson in 2009-2010.
His memorable 93rd minute equaliser was the 11th goal scored in this fixture after the 80th minute in the last 25 clashes but only the third scored by Barnsley.
Both teams scored in this fixture for the third time in the last six meetings, however the Owls have scored in nine of the last 10 meetings.
This was only the seventh draw in the past 33 meetings and only the 14th in 70 clashes in total.
Barnsley started the season only drawing one of their first 14 league matches, but since then they have experienced a stalemate in nine of the following 25.
The Reds have drawn each of their past three home matches (all 1-1) and have now failed to win any of their last six at Oakwell, conceding the first goal in five of those six.
Overall Barnsley have now won only one of their last 11 league games and have dropped into the bottom half of the Championship for the first time since the 26th November (when they were 18th)
Barnsley have now scored 16 times in the 80th minute or later- seven of which have come in the 90th minute or later. It is the first time they have scored this many post-80th minute goals since the 1996-1997 promotion season when they also scored 16.
It is only the second time in the past 19 meetings with Wednesday where Barnsley have netted in the final ten minutes, in that time the Owls have achieved it four times.
