Called into action twice by Leadbitter in the first half and had to parry a stinging drive away from goal. Was equal to everything thrown at him but never really tested.
The fastest out of the blocks in the Swansea back four, always attempting to snuff out chances early on. A commanding presence as ever.
Looked as though he may struggle with Leadbitter in the first half, but became more and more assured as Middlesbrough faded.
Found Shechter with a cross in the first half but the striker could not beat Steele with his header. His role changed slightly when Routledge was brought off. A solid performance.
Tried to be positive but was caught out of position on a couple of occasions in the first half. Benefited as Swansea started to dominate and was able to get forward on more occasions.
Struggled to find an opening in the first half, with just one shot deflected wide off Bikey to show for his efforts. Moved further forward in the second half and combined well with Dyer and Ki.
A quiet first half but saw more of the ball after the interval and nearly played in Moore with a flick-on. Substituted for Ki with less than half an hour left.
Looked frustrated by a lack of options as he attempted to break on the counter before the interval, but enjoyed much more of the play after the break and threatened on a number of occasions.
The first Swansea player to unlock the Middlesbrough defence with a drilled pass to Ben Davies after half an hour. A typical display from the midfielder who enjoyed more of the ball in the second half.
J. de Guzmán
An understated performance from the midfielder, whose influence grew as the game progressed. Rattled the bar with a curling free kick, and took the corner that was glanced in by Hines.
Might have done better with a Ben Davies cross in the first half, which eventually deflected off Dyer and into Steele's grasp. Replaced shortly after the interval by Moore.
Only act of a quiet opening 30 minutes was to kick the ball into touch, but did eventually have to gather a deflected Shechter header before the break. Made a vital fingertip save to deny De Guzman from a free kick. Could do nothing about the Hines own goal.
Provided Leadbitter with a chance in the first half after an excellent run and excelled on the left before moving into the centre of defence in the second half.
Blasted an effort well wide after the break, when it might have been easier to play in Ledesma. Dealt well with the twin threat of Davies and Routledge for most of the game, though let the full-back in on a couple of occasions.
A very impressive display from the 24-year-old, who harried Michu, Shechter and Routledge in the first half, but was unfortunate to head into his own net and decide the match in Swansea's favour after what appeared to be a game-saving tackle on Ki.
Found Leadbitter before the interval with a clever pass but the chance was not taken. Forced off with an injury in the second half.
Had a handful of chances throughout the game but only really tested Tremmel once with a drive the goalkeeper had to parry. Came off for Miller late on.
Was able to impose himself more on the game as the midfield opened up after the break, but was forced deeper as the half wore on. Booked for a foul on Dyer.
The quietest of the Middlesbrough front men. Struggled to create any genuine chances, with Leadbitter and Jutkiewicz far more involved.
Looked to find Jutkiewicz early in the first half with through passes, but saw his influence on the game dwindle in the second half.
Saw an early diving header comfortably saved by Tremmel, but otherwise allowed his side to switch between short and long passes with solid hold-up play.
