Ulverstone has taken third spot on the NWFL off East Devonport after disposing of the Swans by 52 points on Saturday.
The Robins won 19.13 (127) to 11.9 (75) at Ulverstone Recreation Ground, bouncing back from last week's shock loss to Devonport in an impressive fashion.
Unlike last week, the Robins were switched on from the first bounce, and led by 27 points after an innaccurate first quarter which saw it kick 5.6 to 1.3.
It pushed its lead to 36 at half-time and looked like running away with it in the third before East responded.
Back-to-back goals cut the margin to 26 late in the third, before three goals either side of the final change ended the chances of a comeback win.
Claye Sculthorpe was Ulverstone's best scoreboard contributor with four goals, which came after hurting his elbow in the first term, with Tyler Everett and Harrison Barker putting in strong showings for the winners.
Sam Greaves bagged four goals for the Swans, joining Kurt Hanson and Shaun McCrossen as their best.
In the other game on Saturday, Penguin won the battle of the winless sides over Latrobe by 42 points, 12.12 (84) to 5.12 (42).
Coach Chris McDonald led the way with six goals as his side made its move with a seven goal to two first half.
Jayden Van Essen, Jake Wray-McCann, Brayden Purton were other Two Blues to impress.
Callum Butler, Jade Smith and Tyler Kelly were Latrobe's best.
