Second-half strikes from Emmanuel Latte Lath and Marcus Forss earned Middlesbrough victory over an improving Queens Park Rangers side who were beaten for just the second time in 10 games.
QPR had the better of the first half, controlling possession and going close through Sam Field, Ilias Chair and Chris Willock.
But Boro, who move up to 11th, were vastly improved after the interval and led when Latte Lath steered a clever shot past keeper Asmir Begovic.
And Forss made sure of Boro's second win in two games when he squeezed a shot home at the near post.
