Already securing their place in England Premier League for next season, Sunderland were losing a bit of intensity as they suffered a disappointing defeat on their last league fixture.
Eager to entertain their home crowd at Stadium of Light, Sunderland immediately put their opponent's under pressure.
However, instead of getting themselves in front, the host found themselves trailing when Nathan Dyer scored after just seven minutes of play.
Things got even tougher for Sunderland when Marvin Emmes made it 2-0 for Swansea on 15 minutes.
The home team's hope in getting back on level terms rise when Fabio Borini pulled one back on 50 minutes.
However, within just four minutes, Swansea regained their two goals advantage as Wilfried Bony scored his side's third to end that tie 3-1 for the visitor.
