The second half started just like the first with Joe Daniher marking inside 50 and kicking a goal.
The Bombers had the first four scoring shots of the second half but from the Swans first forward entry they were able to mark and goal.
Michael Hurley was moved onto Lance Franklin, Patrick Ambrose shifted onto Sam Reid and Michael Hartley moved to Callum Sinclair.
The Bombers kicked 2.4 in the third term to the Swans four goals straight.
Sydney's efficiency in attack was one of its dominant features. Nearing the end of the match the Swans had scored from 51 per cent of their inside 50 entries and had kicked at goal with 76 per cent accuracy.
In the end it was a disappointing finish to what had been an exciting season for the Bombers.
