Michael Carrick enjoyed his first victory as Middlesbrough head coach as two own-goals helped them win at Hull City.
Chuba Akpom headed the visitors in front before half-time only for Cyrus Christie to equalise on the hour mark.
But own-goals from Tobias Figueiredo and then Christie settled things as the visitors climbed up to 18th, two places above the home side, who suffered a sixth defeat in their last seven games at the MKM Stadium.
Akpom had scored in Carrick's first match in charge at Preston North End on Saturday and he repeated the feat for his sixth of the season.
