Leeds secured their biggest victory at Oakwell since 1983 when they also won 2-0. They are only the third Leeds team to pick up three points at Oakwell in 18 years (2017, 2014, 1997)
It was only Barnsley's second defeat in seven Oakwell meetings - they had won five of the last six.
In this fixture home and away Barnsley have conceded the first goal in the last four, including both of the last two at Oakwell.
This is the second time in three Oakwell meetings that Barnsley have failed to score - prior to this they had scored in nine successive Oakwell meetings.
This was the first time in four home games this season Barnsley conceded a first half goal.
It is only the second time The Reds have conceded two first half home goals this season, and the other was also when the SKY cameras were here, the 3-0 defeat to Aston Villa.
These are also the only two occasions this season Barnsley have been two goals behind at home at half-time.
Ezgjan Alioski scored Leeds' second after 49 first half minutes -, it is the third time Barnsley have conceded in first half injury time in the Championship this season but this is the latest.
This was the fourth time in 10 home league games this season that Barnsley have conceded the opening goal. It has now happened in successive home games for the first time since February when they conceded first against Brighton and Huddersfield.
February was also the last time Barnsley have gone back to back home games without scoring, following up a 0-0 draw with Preston with that 2-0 defeat to Brighton.
Barnsley have now failed to win any of their 10 games this season in which they have conceded the first goal, drawing three and losing seven. The last time The Reds won when conceding the first goal was actually against Leeds, back in January.
For the second season in a row a goal was scored on half-time in this fixture - Tom Bradshaw made it 1-1 on 45 minutes back in January.
This was Leeds fifth away Championship success this season - they have won every away match in which they have opened the scoring in.
To try and change the game Paul Heckingbottom made two half time changes, the third time he has done this in 2017-2018 (also against Sheffield United and Aston Villa) all three games The Reds have failed to score.
There were 16,399 in attendance, 1,418 down on last season's Oakwell tv encounter.
Adam Hammill picked up his fifth yellow card of the season, three of them have come in Yorkshire derbies (Sheffield United, Sheffield Wednesday, Leeds) His other two came on the opening day at Bristol City, and in the other televised match, v Villa.
This result continues Barnsley's woeful home record since returning to the division in 2016. They have played 33 Championship games at Oakwell since winning promotion and won only nine- this includes winning their first three home games back in the division.
Barnsley have failed to score in 3 of their last 4 home games - prior to this they had only failed to score in one of their last eight at Oakwell.
So far in 2017-2018 they have failed to net in four of their league matches at Oakwell, they only failed to score in five home games in the whole of 2016-2017.
Samuel Saiz opened the scoring at Oakwell, meaning he has now had a hand in 13 goals for Leeds this season in all competitions (nine goals, four assists)
Gary Gardner was shown a yellow card in the game, only the second Barnsley sub to be booked this season after Adam Hammill on the opening day.
Barnsley had 53% ball possession, meaning they have enjoyed more ball possession than their opponents in four successive matches.
There were 33 shots attempted (14 for Barnsley, 19 for Leeds) the second most in an Oakwell game this season (v Ipswich 34)
Leeds forced 12 corners, they have had the most corners at Oakwell of any opponent since The Reds returned to the Championship, also forcing 11 in January.
