The 17 match winless league run finally came to an end with a convincing victory over inform Hull City.
The Reds secured only their second win of the season in all competitions against a Tigers side who had won four of their previous six Championship matches.
It also ended an eight match winless run at Oakwell.
Barnsley have gone back to back games conceding less than two goals for the first time this season, however they have now gone 13 games without a clean sheet, their longest run since a run of 20 between 3rd October 2015 and 9th January 2016 (4 Football League Trophy games, 1 FA Cup, 15 League One)
This was only Barnsley's six win in their last 50 Championship matches (D16 L28)
Barnsley opened the scoring for the sixth time this season but went on to win for only the second time.
They went 2-0 up in a game for the second time this season but went on to win for the first time.
This was the first time the Reds have scored three goals in a game this season and the first time since the 22nd April when they won 3-0 at Plymouth in League One.
It is their first three goal haul in the Championship since April 2018 when they defeated Sheffield United 3-2.
It is the 800th Football League match in which they have scored three or more goals and the 1200th second tier match in which they have scored two or more.
A two goal winning margin is Barnsley's biggest at this level since their final home game of 2017-2018 when they defeated Brentford 2-0.
Barnsley led at half time for only the third time this season, they have won two of the occasions in which they have led at the break, drawing the other - at West Brom.
The victory finally lifted Barnsley into double figures for points.
Alex Mowatt and Mike Bahre became the second and third Barnsley players to both score and assist in a game this season, after Conor Chaplin against Blackburn.
It is the first time two Barnsley players have scored and assisted in the same game since Kieffer Moore and Mamadou Thiam did so in a 4-1 win at AFC Wimbledon in January.
It is the first time in a Championship game since a 3-0 success against Sunderland in August 2017 (Ike Ugbo, Harvey Barnes)
Bahre grabbed his first ever Championship goal and only his third goal for the club in 55 appearances.
Barnsley have gone back to back games without bookings for the first time this season.
Barnsley have now won three of the past five meetings with Hull and three of the past five at Oakwell.
Barnsley have now had the most ball possession for the fifth successive league game.
Despite four goals being scored there were only 17 shots in the game (11-6), the lowest in a Barnsley game this season and lowest since Portsmouth away in February (also 17)
This was the second time this season that Barnsley have restricted their opponents to just one shot on target and in both games they have scored with it (also Nottingham Forest)
