Williamstown edged out traditional rivals Port Melbourne by three points in a Victorian Football League thriller at North Port Oval on Saturday.
The Seagulls led most of the way until former player Anthony Anastasio bobbed up with a goal to put the never-say-die Borough in front at the 10-minute mark of the final term.
In a low scoring affair with only 13 goals kicked between the two sides, the next goal would be the deciding one and it came through Williamstown onballer Michael Gibbons.
Midfielder Willie Wheeler was the Seagulls best with a stunning 36 possessions, 17 tackles and two goals. Jason Pongracic was also a tackling machine, finishing with 17, while big man Nick Meese gave first use to the Seagulls onball unit with a whopping 67 hit outs.
The stirring victory had the Seagulls on top of the ladder on Saturday night, but Box Hill re-claimed first place with a win over Werribee on Sunday.
However, it has created a handy eight-point buffer for the Seagulls in the top four ahead of a tasty encounter with Footscray at Burbank Oval this Saturday.
The Bulldogs will go into the local derby on the back of a three-game winning streak.
The Dogs made light work of the Coburg Lions, running out 60-point victors at the Victoria University Whitten Oval on Saturday.
Lukas Webb starred for the Bulldogs with 33 disposals and four goals, while Matthew Boyd racked up a game-high 38 possessions.
