Middlesbrough have beaten Bolton Wanderers 1-0 in the Championship at the Riverside Stadium.
In Aitor Karanka's first home game in charge, it was Grant Leadbitter's late penalty that secured the points.
Jermaine Beckford missed a spot kick for the visitors to confine the Trotters to their first defeat in nine games.
With neither side creating much in the first half, it was Kei Kamara who had one of the better chances, but his 11th-minute effort went wide of the Bolton post.
George Friend also had an effort for the home side, while Jay Spearing did well to block Jacob Butterfield's attempt on 21 minutes.
Marvin Emnes was brought down eight minutes from time to give Leadbitter the opportunity to claim the winner, and the former Sunderland man made no mistake from 12 yards.
Beckford spurned a late chance to get his side a point when he fluffed his own penalty with minutes remaining.
