Dylan Riley achieved the rare feat of a 10-goal haul as a magnificent premiership quarter set Launceston up for a massive 125-point win at North Hobart.
Just eight points ahead at half-time, Mitch Thorp's men piled on 13.5 to one behind in the third quarter to lead by 90 and kill off the contest.
More of the same in the final term led to a comfortable 25.18 (168) to 7.1 (43) win.
The fourth quarter boiled down to one subplot of whether Riley could reach double figures and Brendan Taylor ensured he would, unselfishly handing off after taking a towering mark.
A demoralised North Hobart had to wait until the 21st minute of the last quarter to add to its goal tally.
The shellacking came two weeks after the Demons lost by 113 points to North Launceston.
Riley's bag saw the reigning Hudson Medallist leap above cross-town rival Thomas Bennett at the top of the goal-kicking charts.
Cody Thorp also kicked three with Colby McKercher, Brodie Palfreyman, Jay Blackberry and Brayden Pitcher other multiple scorers for the Blues. Despite Riley's goal-kicking heroics, Michael Musicka was adjudged best on ground.
A third straight win and healthy percentage boost also cemented Launceston's position at the top of the ladder.
Tigers were too good for Glenorchy, winning 10.12 (72) to 6.12 (48) with Tyler Carter and Harrison Gunther both kicking three goals.
