Helpless to prevent the opener and beaten by a wonder strike when Watson's free kick flew past him from over 30 yards out.
His looped header back across goal should have been converted by Cala but it was tipped onto the post and wide. Will have been disappointed to see McCann unmarked at the back post for the opener as he failed to marshal his defence.
Defended stubbornly all game and wasn't frightened to get forward and offer support down the left flank. Looked assured in possession.

A quiet afternoon in an attacking sense as he was tasked with keeping McManaman then McClean quiet. Both gave him a difficult time and saw Gomez break free down his side for the opener.
Came agonisingly close to pulling Cardiff level for the second time when his header was tipped onto the post in the last move of the first half. He really ought to have scored. A solid debut otherwise.
Won several free kicks for his side in advanced situations as he tried to make things happen. Didn't quite trouble Wigan as much as his manager would have liked, however. Replaced late on.
The former Manchester United man had a quiet game and struggled to cope in the midfield battle. Came close to the equaliser when his effort from the left-hand side flew over the bar.
Replaced at half-time after a quiet first half. Didn't see too much of the ball with lots of Cardiff's play going through Zaha and Campbell.
His trickery and pace proved a real handful for the visitors all afternoon. Provided several quality crosses into the box but was guilty of losing possession in advanced areas on a few too many occasions.
Showed real composure to pounce on a scramble in the area and fire his side level with a left-footed strike into the bottom corner. Unlucky to see a header hit the bar moments later. Lively all afternoon.
Replaced with half an hour to play after a difficult afternoon. Asked to play in a wider role when he is better suited to a more central position. Looked uncomfortable in possession all game and was often dispossessed.

Not at fault when Campbell pulled Cardiff level but did brilliantly to prevent Cala from doing the same as he tipped his close ranger header onto the post.
Saw his early effort fizzle just wide of the far post. Was composed throughout and stood up strong to constant Cardiff pressure down his flank.
The captain was first to everything, with Cardiff enjoying lots of possession in the final third. Organised his defence well in a resolute display at the back.
Linked up well with Boyce in the central defensive partnership. Reluctant to play the long ball and often opted for the neat pass out of defence. Anticipated play expertly.
Some brilliant work down the left saw him break free inside the area and cut back to McCann for the opener. A creative outlet all afternoon for his side. Replaced late on.
An understated game from the midfield man who protected the back four and allowed McCann to provide the legs in the middle. Constant simple passes helped his side move out from defensive positions.
Proved a tricky customer on his wing and won the battle on his flank. His pace caused problems but he seemed to be struggling with injury late on. Replaced by McClean.
Opened the scoring when found unmarked six yards out and smashed his left-footed strike home. A willing runner and tireless worker thereafter. Unlucky not to double his tally when he tried to loop over the keeper from a tight angle.
Mr FA Cup made his intentions clear early on with a defence-splitting pass to send Perch through. Involved in all of Wigan's play and scored a wonder free kick from all of 30 yards out. Replaced in the second half.
Threw himself at everything as Cardiff pressed for the equaliser late on. No nonsense football saw him clear the ball more than pass it but defended bravely.
Looked isolated up front as his side attempted to win the midfield battle and cut a frustrated figure throughout. His strength and pace threatened to send him clear on a few occasions but he just lacked the required composure.
Brought on at half time to offer some stability in midfield and saw a lot of the ball. Kept play ticking over and set up one or two passages of play in advanced positions.
A lively second-half introduction and was a key figure for Cardiff as they chased the equaliser. Lacking a touch of quality in the final third, though.
Introduced with ten minutes to play but failed to make the impact his manager would have been after.
Introduced late on to see the game out.
Introduced for match-winner Watson and helped to see the game out with some composed midfield play.
Picked up where McManaman left off in providing a constant threat down the left wing. Required to offer some defensive protection for Espinoza and did exactly that.
