Williamstown was overrun in the second half by a fast finishing Box Hill Hawks to lose by 28 points in the Victorian Football League at Burbank Oval on Sunday.
The Seagulls had the upper hand at half time, holding a 17-point lead, but their wastefulness in front of goal in the first half kept the Hawks in the game.
A scoreless third term, followed by a wayward 1.5 in the fourth, consigned the Seagulls to their second loss in three games to start the season and left them in unfamiliar territory outside the top eight.
Half back Jake Greiser, onballer Michael Gibbons and forward Ben Cavarra were the standouts for Williamstown, while Cavarra, Arryn Siposs and Leigh Masters, in his 100th game, kicked two goals each.
Williamstown will be looking to snap a two-game losing run when it hosts Coburg Lions at Burbank Oval on Sunday.
Meanwhile, Footscray ran riot to beat North Ballarat by 124 points at the Victoria University Whitten Oval on Friday night.
The Bulldogs kicked 25 goals to five, including 17 in a second half blitz.
Nathan Mullenger-McHugh, Declan Hamilton, Tory Dickson and Mitch Wallis kicked three goals apiece for Footscray.
The returns from injury of Dickson and Wallis were pleasing for the Bulldogs.
Wallis, who sustained a sickening broken leg last season, hit the ground running to produce a stunning best-on-ground performance.
Shane Biggs and Lukas Webb also staked their claims for Western Bulldogs call-ups with strong outings.
Footscray will host Richmond at Etihad Stadium on Saturday at 3.30pm in a curtain-raiser to the Western Bulldogs clash with the Richmond in the AFL.
Meanwhile, VU Western Spurs will open its VFL Women’s season on the road on Saturday away to Cranbourne.
