Carlisle United are out of the play-offs. But they gave it a real go in the second half - beaten only by a controversial stoppage-time winner from on-loan Swansea striker Darryl Duffy.
Carlisle defenders and manager Neil McDonald thought Duffy had handled as he bundled the ball in, but he said afterwards: "I'd like to think I'm an honest player and I didn't handle it."
You can't afford to give play-off rivals a goal start and United were behind in the first minute.
A quick free kick out to the right from Andy Robinson found Leon Britton, whose hard low cross reached Lee Trundle. He turned on a sixpence 14 yards out to hammer the ball past keeper Kieran Westwood.
After that Swansea ran things up to the interval, with a strong wind at their backs.
While Carlisle seldom got beyond the stage of exchanging passes in midfield, Swansea created the chances.
Robinson was just off target with a free kick from the edge of the box and a great Danny Livesey saving tackle checked Duffy after Trundle put him clear. Then in the 33rd minute Duffy finished tamely after Peter Murphy slipped to let him in.
Clearly after the interval if Carlisle were to go out of the reckoning they were going out with a shout rather than a whimper. And with Swansea themselves refusing to settle for a draw it added up to a cracking 45 minutes.
American star Johann Smith set the scene when he chased Chris Lumsdon's high ball, cut inside two defenders and the keeper to hammer the equaliser.
As Swansea swept back, keeper Westwood juggled with a Trundle shot but the ball spun up off a defender.
Two minutes later he made a great one-handed save to turn Robinson's shot for a corner.
United should have taken the lead on 67 minutes, when Johann Smith's pace took him clear of Kevin Amankwaah down the right. With Lumsdon free in the middle he elected to shoot from a tight angle, and the keeper played the ball against a defender.
Continuing the end-to-end stuff, skipper Murphy allowed Trundle to get on his wrong side but Westwood turned his close-in shot for a corner.
It was into time added on when a Smith shot went just wide and Duffy notched the all-important winner.
After the match, manager McDonald said: "We were outplayed in the first half but we changed it and caused them a lot of problems. We were fantastic in the second half and Johann Smith took his goal well.
"Survival was the aim at the start of the season and we're miles past that.
"Maybe finishing in the top half of the table will mean we can attract players next season."
