Middlesbrough kept up their promotion push with a deserved 3-1 win at Cardiff City Stadium.
Marcus Forss' powerful finish gave Boro a 17th-minute lead as the visitors were rewarded for a dominant start.
Cardiff equalised when Zack Steffen gave the ball away, allowing Sory Kaba to score his first Bluebirds goal.
Cameron Archer put Boro ahead before the break, before Riley McGree rattled home a third in stoppage time to cap a fine performance from Middlesbrough.
The victory saw Boro retain third place in the Championship, but Sheffield United's win over Cardiff's bitter rivals Swansea meant Michael Carrick's side failed to make up any ground on the automatic promotion spots.
