The Swans went unrewarded at Norwich despite a strong performance against the Canaries.
Paul Lambert's side started out on top but the visitors went on to dominate large periods of this affair and had attempts to break the deadlock.
Stephen Dobbie, David Cotterill and Scott Sinclair all had chances but the best fell to Cotterill six minutes from time when his spot kick was saved by John Ruddy.
This spurned on the home side who struck twice in the closing moments through an Ashley Williams own goal and Simeon Jackson strike to seal maximum points.
The only change to the visitors' line-up came at right-back where Albert Serran took the place of the injured Angel Rangel.
One Catalan replaced another with Rangel set to miss out for the next four to six weeks with a thigh injury.
Swans boss Brendan Rodgers continued with his attacking blend of football with David Cotterill holding his role behind striker Stephen Dobbie.

Weather conditions in Norfolk just couldn't be compared to that of back home with players and fans alike struggling to avert the strong rays from their eyes.
And it was the visiting side that had the misfortune of playing into the sun to start and Norwich took advantage - starting strong and going close early on.
The Swans defence had to be at their best to deal with Andrew Surman's free-kick into the area while Wes Hoolahan fed skipper Grant Holt the ball but his effort was blocked.
But just like the previous weekend against Preston, Brendan Rodgers' side looked dangerous going forward and with nine minutes played Scott Sinclair had their first chance when he fired over.
Nathan Dyer endured similar fate as he was off target with his strike after David Cotterill's corner was cleared, while Dorus de Vries was the first 'keeper called into action when he denied Korey Smith following a counter attack.
But after that the Swans settled into their surroundings and continued to look threatening as they went forward; this was evident just before the half-hour as Darren Pratley rose above his marker to head a Cotterill corner inches over the top of goal.
Stephen Dobbie had an even better chance to break the deadlock moments later as he was picked out unmarked by Scott Sinclair inside the area, turned and fired towards the bottom corner only for Michael Nelson to stand strong and block his effort.
He did have the better of 'keeper John Ruddy nine minutes before the break, however, when he latched on to Albert Serran's clever long pass, his touch beat Ruddy but fell just the wrong side of the post, and another sweeping move moments later left Norwich players standing as Dyer got in behind his marker and pulled back to Cotterill who was well off target.
Half-Time: Norwich 0 Swans 0
The Swans started the second-half just as they finished the first, in attacking fashion.
Within 60 seconds of the re-start they were causing problems down the Canaries' right-hand side while Neil Taylor was given his first taste of Championship action at left-back after coming on for Albert Serran.
But Norwich certainly weren't going to sit back and soak up the pressure. They were seeking a first home league win this term and on 49 minutes Dorus de Vries denied Wes Hoolahan with a smart save after Cotterill was robbed of possession by Surman.
Normal service resumed five minutes later when Scott Sinclair used one his main attributes - speed - to ease his way past three defenders into the area to charge down on goal but, at the final hurdle, he was denied by Ruddy's strong hand. Cotterill also tried his luck from 20-yards moments later only for the head of Elliott Ward to guide the ball safely over the bar.
Andrea Orland was introduced just after the hour in place of Nathan Dyer and he played a part in the build-up which saw Stephen Dobbie curl wide of the post, while Ruddy was called into action to deny the Scotsman 60 seconds later following more fine work by Sinclair.
Paul Lambert's side battled back but rarely caused de Vries and his defence any problems, and with six minutes remaining they were handed a lucky escape after referee Phil Crossley awarded the visitors a penalty.
The pace of Sinclair got the better of the defence as he raced onto Andrea Orlandi's through ball and as he entered the area was brought down by Ruddy. David Cotterill placed the ball only to see his spot kick pushed onto the foot of the post.
At that point the atmosphere inside Carrow Road was lifted for the first time in the second-half, and it had a desired affect as Norwich spoilt what had been a good day at the office for Swansea. Grant Holt fed substitute Anthony McNamee out wide and his deep cross was turned into his own net by Ashley Williams at the near post.
That lead was doubled deep into injury-time when another substitute, Simeon Jackson, turned home Holt's cross unmarked from 10-yards.
