Luke Murfitt-Cowen cemented Longford's position at the top of the ladder and his own atop the goal-kicking charts with a bag of 10 in a 113-point thumping of Hillwood.
The prolific forward accounted for nearly half his side's score in a 22.13 (145) to 5.2 (32) victory as his season's goal tally blew out to 34, 11 clear of Deloraine's Darren Banham.
Hillwood coach Jake Pearce said during the week how his side was planning for the gun forward but the Sharks had no answer, conceding nine goals inside the first term.
Nash Digney finished with a couple for the eighth-placed home team.
Joshua Gray and Liam Davies also kicked three apiece as the Tigers gave a debut to 2018 under-18 premiership player Will Dakin.
After two wins in three weeks by less than a kick, Bridgenorth went a bit easier on coach Phil Lethborg's blood pressure but lost by nine points at Deloraine.
The fourth-versus-fifth clash involving two teams on 12 points proved to be as close as expected as the Roos came from behind to win 8.11 (59) to 7.8 (50).
The Parrots led at the first two breaks but just one point in the premiership quarter proved their undoing despite outscoring their opponents in the final term.
Banham kicked three goals and Lachy Dornauf two for Deloraine although Rohan Sergeant was the game's leading scorer with four for the plucky Parrots.
The evening derby clash between seventh-placed Scottsdale and winless cellar-dweller George Town was stolen by the Magpies 12.13 (85) to 2.2 (14).
Kyle Lanham kicked eight, Shane Baker four and Joseph Robinson three.
South Launceston had the bye.
The game of the indigenous round will see Rocherlea host Bracknell at 2.30pm on Sunday.
