After Judah Edmunds opened the scoring in the win over Lauderdale, 18-year-old Bailey Mitchell hit the scoreboard early in Saturday's 13.10 (88) to 7.10 (52) win over Kingborough.

A late inclusion after vice-captain Mark Walsh was ruled out, the younger brother of fellow first-year Bomber Lockie made the most of his first impression.

"It was a pretty special goal," North Launceston coach Brad Cox-Goodyer said.

"He was running towards the boundary line, a bit of pressure on him and he slotted it which was really exciting.

"He didn't look out of place either young Bailey - that's [debutant] number 18 for the year which is really positive, we'll just keep blooding them."

The Bombers' eighth-straight win looked cruisy on the scoreboard, but had some nervous moments in the last term when Kingborough closed the margin to 16 points.

North showed its maturity in landing the game's final punches as Cox-Goodyer (three goals) and in-form skipper Jay Foon led from the front.

Cox-Goodyer said his young side had plenty to work on, but was still finding ways to win.

"We felt like we were on top for most of the day," he said.

"It was just a couple of skill errors and things we spoke about that we didn't want to do - bombing it long when they're putting a lot of numbers behind the footy and we continually did that, so that was a bit frustrating.

"But we managed to grind it out and kick away in the end which was nice.

"We've still got a lot to get right, but we do a lot right as well."

Jack Avent suffered a corkie early in the first term, but managed to play out the game.

"He wasn't able to play like he plays - we lost him in on-ball rotations," Cox-Goodyer said.

"I thought Alex Lee was really good coming back, Judah Edmunds gave us another really good effort and Foony was really good around the ball as well.

"Declen Chugg was good again and it was one of those team efforts really."
