Isaiah Jones' first goal of the season gave Middlesbrough victory against an out-of-sorts Swansea City.
After an uneventful first 25 minutes, the game came to life when Jones beat the offside trap to break clear and calmly beat Ben Hamer to open the scoring.
Swansea rarely threatened in the first half but were much improved after the break, and Joel Piroe thought he had drawn them level only to see Paddy McNair clear his shot off the line.
Victory moves Chris Wilder's Boro above Swansea and up to ninth in the Championship, while back-to-back defeats for the first time this season sees the Swans drop to 12th.
