Laharum's pressure forced Swifts to regularly turn over the football, as the Baggies struggled to play their usual attacking game.
Swifts coach Paul Hanns described it as a 'rough day'.
"Things just didn't go our way," he said.
Laharum coach Marcus Demaria was rapt with his side.
"Our focus was on applying pressure and we were able to execute our game plan well," he said.
Demaria kicked five goals in the win, with Jason Przibilla kicking seven.
"Our forward line is working better," Demaria said. "Earlier in the season we were too top heavy, but we're getting the balance right."
