Barnsley slumped to their fourth defeat in seven games in all competitions.
The Reds have failed to win any of their last four home league games, and have now won only eight of their last 30 league outings at Oakwell since the start of last season.
Barnsley have now kept only one clean sheet in their last 17 league games home or away and that came this season in a 3-0 win over Sunderland.
It was Hull's first league WIN on the road since their first away game of last season when they were a Premier League side. The Tigers had gone 24 games (427 days) since their last victory away from the KCOM and had picked up only six points from a possible 72 since a 2-0 win at Swansea on the 20th August 2016.
It was also Hull's first clean sheet on the road since a 0-0 draw at Southampton in April (9 games all comps) and only their sixth ever at Oakwell in 51 visits, and the first since 1989.
Fraizer Campbell grabbed the Hull winner- his first ever professional goals were for Hull against Barnsley - a brace in a 3-0 win in October 2007. His goal yesterday came from the Tigers first effort on target, and immediately after Angus MacDonald had replaced Adam Jackson in the Barnsley defence.
His goal came in the 78th minute, three other Championship teams also scored in that minute (QPR, Brentford and Nottingham Forest)
Hull are undefeated when Campbell has scored (W16 D4 L0) with two of those victories coming against Barnsley.
A Barnsley league game was goal-less at half time for only the second time this season (also at Wolves). It was the first Oakwell league match to be 0-0 at the break since Cardiff's visit on the 4th April
The Reds have failed to win any of their last 10 matches (all comps) that have been goal-less at the break, the last time they managed a victory from this position was in a 1-0 win at Rotherham in January.
Only one team has scored in each of the last four meetings, leading to two wins for Barnsley (1-0 and 2-0) and two wins for Hull (1-0 and 1-0)
This was only the third time in nine league and cup games at Oakwell this season that Barnsley did not open the scoring and was only the second time they have failed to score (also 0-3 v Aston Villa)
Barnsley had 52% possession in the game, only the second time this season they have enjoyed more possession than their opponents (61% v Villa)
They had 23 shots compared to Hull's eight (both the most they have attempted and the least they have conceded this season)
It is the most they have had in a game since the 25 they attemped in the 1-1 draw with Brentford in April, and the least they have conceded since the six Cardiff managed in the 0-0 draw, also in April.
