Fraizer Campbell scored a late goal as Hull beat Barnsley 1-0 in the Sky Bet Championship to secure a first away league victory since August 2016.
The result at Oakwell pushes the Tigers up to 14th in the table and leaves Barnsley in 19th, hovering dangerously close to the relegation zone.
Substitute Campbell broke the deadlock with a goal from a corner in the 77th minute, ending the visitors' miserable run of away form which had seen them pick up just six points from a possible 72.
After a slow start, Barnsley registered the first attempts at goal, with winger Harvey Barnes and left-back Zeki Fryers firing shots high and wide.
