NORTH Melbourne has outclassed Melbourne at the MCG tocontinue the longest spell of club domination in recent history.

For the 12th straight time, the Kangaroos emergedvictorious over the Demons, winning 15.17 (107) to 10.6 (66) on Sunday.

After an error-strewn first half, North Melbourne put thefoot down in the third term, kicking seven goals in a dominant spell to end thecontest.

Despite the convincing win, Roos coach Brad Scott was lessthan impressed with his team's performance.

"There were some things that we were reallydisappointed with in terms of the way we played," he said.

"We've got to hold ourselves to a high accountbecause that's what really good teams do and we're not a really good team yet,so we've got to keep striving to become one.

"Opportunities going forward we had a few 12-pointplays where we not only squandered an opportunity to score for us but we openedourselves up on the rebound.

"Again, really good sides don't do that."

Demon Bernie Vince's 41 touches and three goals were insharp contrast to the Kangaroos' even spread.

They had 12 goalkickers in a twilight clash that will helpRoos coach Brad Scott erase the memory of their loss to Adelaide last round.

The Demons went goal-for-goal with the Kangaroos in thefirst term but were hampered by turnovers.

North Melbourne's first five goals all started from Demonerrors, though the Kangaroos weren't much better themselves in the second term.

Time after time, players from both sides turned over theball by hand and by foot, with Scott Thompson even missing his hand in anattempted handball.

Melbourne recovered to kick three straight goals and stayin the contest.

Two goals down, Melbourne started well after the mainbreak with Chris Dawes converting after a strong tackle on Shaun Atley.

But from that point the Kangaroos were utterly dominant,with Jack Ziebell and Atley's goals starting the rout.

Lindsay Thomas, Andrew Swallow and Aaron Black then putNorth Melbourne clear with majors in a five-minute burst.

Debutant Ben Brown, playing in the No. 50 guernsey, wasmobbed by teammates when he kicked his first AFL goal and their sixth in a row.

North was rampant, and even out-tackled the Demons despitedominating possession.

Exemplifying the Demons as a team in transition, lastweek's hero Christian Salem didn't have a possession until deep in the secondquarter and was substituted in the third.

Melbourne coach Paul Roos thought his side was mentallyfatigued.

"It's certainly not as good as we've been playing. Ijust thought some of our guys looked really tired tonight, some of the youngguys," he said.

"We're getting to the middle of the year, that's themental challenge for teams where we are is getting up week-in, week-out.

"I thought we went away from some of the real basic thingswe've been doing really, really well."

Midfielder Jordie McKenzie will also be heavilyscrutinised for a raised elbow, which laid out Thomas in the second term.

The worst news of Scott's day was a shoulder injury toRobin Nahas that led to his early substitution.
