Playing just his seventh TSL game, 18-year-old Morris kicked his first senior goal a minute into the first term and finished with nine for the day.

Only Riley (10 goals against North Hobart earlier this year) has kicked a bigger bag in the past few TSL seasons.

After conceding two of the first four goals at a sandy Windsor Park, Launceston kicked 26 of the next 29 in a romping 28.13 (181) to 5.5 (35) victory.

The result was undoubtedly disappointing for the sixth-placed Magpies, who are undergoing a club review, but was well-received by Blues coach Mitch Thorp.

"It was nice to see some of our younger guys go to work and really put their hand up at the pointy end of the year," Thorp said.

"[Zach] is a super kid and he's been really committed to our program all season.

"I think the important part to note was that six of his nine goals came on Harrison Gunther who is a pretty good footballer - it probably speaks of how talented Zach is.

"He was brilliant today, and Josiah Burling in a slightly different role had nine marks, so they're the things we're really looking for to settle on what our best side looks like."

The Blues finished with 13 goalkickers - one fewer than last week - and slotted 10 majors between the 17-minute mark of the first term and the 13-minute mark of the second to kill the game.

Morris kicked three of his nine in the final term, while the play of the day came minutes from the final siren as Casey Brown topped off a Harlem Globetrotters-style one-hander with a running goal from a tough angle.

Earlier, both sides swung two late changes before the game, with Glenorchy losing number one ruckman James Duigan and the Blues adding Tasmania Devils pair Morris and Bailey Gillow.

Late out Isaac Hyatt impressed in a 170-point development league win, while Cody Thorp (managed) joined the remainder of Launceston's gun ruckmen Joe Groenewegen (managed) and Hamish Leedham (isolation) on the sidelines.

Makeshift ruckmen Jake Smith and Jamieson House ensured it counted for little, however, as the Blues dominated clearance after clearance against an under-fire Magpies midfield.

Thorp said it had been important to rest Groenewegen and his younger brother, who spent the day as a runner, in the lead-up to Clarence next weekend and a finals series not long after.

"It was probably more an age thing than a positional thing - we want to look after our guys in their late 20s and Wagon and Cody obviously both fit into that category," he said.

"We've got some big games ahead of us this year and we needed to make sure we managed our guys at the appropriate time."

Brendan Taylor (four goals) also enjoyed a day out in front of goals for the Blues as teammate Jake Hinds (three) moved into equal-fourth on the league charts.

Veteran Jay Blackberry had an otherwise good day soured by being reported for a sling tackle in the third term.

Things were much closer in the other two games as Kingborough and Lauderdale stole thrilling come-from-behind victories.

Playing at Bellerive for the first time since 2019, Kingborough trailed trailed Clarence at every break, and by as much as four goals in the second term, before Luke Graham snapped the winner right on the final siren.

The 9.14 (68) to 9.9 (63) victory bumped Trent Baumeler's Tigers back into third spot two rounds out from finals.

The Tigers host North Launceston before a last-round bye, while Clarence meets Launceston and North Hobart.

At Lauderdale, the hosts trailed by 33 points at the main break before fighting back to deny North Hobart its second win of the season.

Allen Christensen was best on ground in the Bombers' 9.11 (65) to 9.9 (63) win.
