An early header from Sean Morrison and Josh Murphy’s brace handed the Bluebirds victory at the Riverside Stadium, with Britt Assombalonga’s free-kick merely a consolation.
But who caught the eye for Boro? Joe Nicholson has dished out his marks from the defeat - and you can scroll down to see how he rated the individual displays:
1. Aynsley Pears
Could be heard barking out instructions to his defenders throughout. Almost caught out when trying to punch a cross in the first half and was a little slow of his line at times. 5 Photo: COPYRIGHT (C) FRANK REID 20187
2. Anfernee Dijksteel
Most of Cardiff’s attacks came through the middle in the first half, yet the right-back was sucked in by Tomlin for the visitors’ second, allowing Murphy space to score. 5 Photo: Nathan Stirk
3. Dael Fry
Won some important headers against Glatzel but lost Morrison on a couple of occasions from corners which led to the opener. Was also beaten by Mendez-Laing for the third. 4 Photo: Alex Davidson
4. Marvin Johnson
Delivered a few crosses into the box from left-back with limited success. 5 Photo: Justin Setterfield
