Barnsley conceded the first goal for the 20th time in 35 Championship games this season, more than in 46 games in 2016-2017 (18)
They last conceded the first goal as many as 20 times in 46 games in the promotion season of 2015-2016.
Oli McBurnie has now scored five goals in six appearances for Barnsley, making him the club's joint second top scorer in 2017-2018.
The on-loan Swansea striker is the first Barnsley player to score in three successive games since Tom Bradshaw against Morecambe, Ipswich and Nottingham Forest in August.
McBurnie has also scored five of Barnsley's last six goals.
He has scored a goal every 86 minutes and nine of his 13 shots have been on target (69%)
Cardiff's Callum Paterson scored in both meetings with Barnsley this season - he is the first player to score in both Cardiff/Barnsley matches since Peter Whittingham in 2008-2009.
Paterson is the first player from any club to score in both league matches against Barnsley since Dwight Gayle for Newcastle last season.
Cardiff complete a league double over Barnsley for the first time since the 2011-2012 season - it is only the second time in the last six seasons the two teams have met that they have achieved it.
Cardiff have though now lost only one of their last ten league matches against Barnsley (W6 D3)
The last four Championship matches between these sides at the Cardiff City Stadium have produced 20 goals (11 for Cardiff, eight for Barnsley).
The victory was the Bluebirds fifth successive Championship triumph, and the first one in this run in which they have conceded a goal.
McBurnie's strike was also the first league goal scored by an opponent at the Cardiff City Stadium in 2018, the only other opposing players to score there so far this calendar year are Kevin De Bruyne and Raheem Sterling.
Remarkably NONE of the bottom half teams won on Tuesday night.
Barnsley had 61% possession in the match, their highest away from home this season.

Cardiff manager Neil Warnock said:
"I said the last 20 minutes would define our season because they had their tails up and we were all at sea.
"I have a great bunch of lads. I can't fault the effort. But people can't ever accuse our team of being physical after what we have seen.
"I was more disappointed at some of the things (that were) allowed to happen but it's another three points and we move on. It's a disgrace, how Kieffer Moore has not been sent off for two challenges I do not know. So, I'm extra pleased that we have stood up to that.
"We missed some easy chances that my wife could have put in."
