Jamarra Ugle-Hagan has steered the Western Bulldogs to a stunning 39-point win over Sydney at the SCG on Sunday afternoon.

With their third straight win over a top-four contender, the Bulldogs recorded the 12.15 (87) to 7.6 (48) victory off the back of pure workrate, handing the Swans their biggest loss since round six last year.

Ugle-Hagan's four goals headlined a big day for the Dogs' tall forwards, with Aaron Naughton (18 disposals, 10 marks) and Sam Darcy (10 disposals, one goal) also wreaking havoc on Sydney's defence.

While the Dogs' height seemed, on paper, to be the biggest challenge for Sydney, particularly with key defender Lewis Melican subbed out with injury in the second term, it was in fact on the deck where it was soundly beaten.

Adam Treloar (40 disposals, seven score involvements), Marcus Bontempelli (22 disposals, one goal), and Tom Liberatore (22 disposals, eight clearances) took charge at the contest, setting the Bulldogs up beautifully right across the ground.

The Western Bulldogs brought the pressure and energy at the ground ball, worrying the Swans into panicked, rushed disposal and capitalising on the turnover.

ALL THE HIGHLIGHTS

A desire to hunt the ground ball was reflected in the contested possession count, which the Dogs won 162-135.

When the Swans did find control, regular scoring wasn't forthcoming, meaning the Dogs' dominant opening term kept the home side at an arm's length for the duration.

Their forward line was powerless in the face of a disciplined Bulldogs defence, further impacted by Logan McDonald's shift down back in the second term.
