A masterclass from Chloe Molloy propelled Sydney to an AFLW record 57 points against the winless Western Bulldogs.

The Swans, who were winless in their first AFLW season last year, achieved their biggest score and biggest margin of victory in their short history with a thrilling performance at Whitten Oval on Saturday.

After a five-goal second term, which included a four-minute burst of three majors, Sydney had already registered their biggest score in an AFLW game by half-time.

The Bulldogs held on in the final quarter, but the damage had already been done as the Swans ran out 14.12 (96) winners to 6.3 (39).

The total was also the most the Dogs had conceded in their history, surpassing Melbourne’s 83 kicks against them in round three.

The Swans stormed out of the blocks with the first two goals just five minutes into the contest.

They took it to another level in the second quarter, putting the result beyond doubt at the main break to lead by 42 points to shock the Bulldogs and their strong home crowd.

Molloy, the Swans’ star off-season signing, produced one of the best performances of his career to demolish their injured hosts.

The former Collingwood ace was a class above as she managed 3.4 from her 28 possessions and played a crucial role in setting up many of Sydney’s other goals.

Ruby Sargent-Wilson, Sofia Hurley and Cynthia Hamilton all scored two goals each in the Swans’ rout.
