Port Adelaide’s brutal demolition of Richmond confirms their status as the wildcards of this AFL finals series.

Power coach Ken Hinkley was rapt with Sunday’s 58-point elimination final win, where they kicked the first seven goals in 18 minutes of mayhem.

Hinkley added they had no fear about travelling to Perth to play Fremantle in a knockout semi-final on Saturday.

As former Cats great Cameron Ling observed during halftime at Adelaide Oval, Port Adelaide’s start against the hapless Tigers sent a ripple through the top four.

Adelaide’s unlikely 1998 premiership is the last time a team outside the top four has triumphed in September.

Also this weekend, defending premiers Hawthorn and Sydney confirmed their status as the top two flag favourites and North Melbourne had an outstanding comeback win.

Geelong, who lost their qualifying final to the Hawks, will play North at the MCG on Friday night in the other semi.

Port Adelaide finished fifth this season, but were on top for eight weeks.

While they dropped out of the top four with six losses from their last nine games, they only lost to the Dockers in Perth by eight points two weekends ago.

“Freo are an amazing side. I love the way they play … I know we’re going to go over there and give a real good account of ourselves though,” Hinkley said.

“We certainly don’t go over there with too many fears. We go over there with a bit of a freedom to play the game.”

Hinkley acknowledged that the 20.12 (132) to 11.9 (75) cakewalk on Sunday was the best Port had played under him.

“It was brutal … it was an awesome display,” he said.

The only setback was a suspected broken jaw for speedster Matt White, who went to hospital for scans.

While Port are building momentum, Richmond have lost their second-straight elimination final after reaching the top eight with a nine-game winning streak.

Port’s runaway win completed an opening weekend of finals where all four games went to form.

But it was far from straightforward, with Essendon ruing a blown chance in their elimination final classic against North.

Fremantle also came within 10 points of Sydney in the last quarter of their qualifying final before the Swans, led by two stunning goals from Lance Franklin, kicked clear.

North enhanced their reputation as masters of the strong finish with their 12-point victory over the Bombers on Saturday night at the MCG.

They trailed by 33 points early in the third term, but roared home on the back of four goals from Ben Brown.

Their veteran Drew Petrie kicked the last two goals of the match, giving them a memorable 14.9 (93) to 10.9 (69) win.

It was a galling end to the season for the Bombers, who again paid for patchy form during a match.

At the ANZ Stadium on Saturday, Dockers coach Ross Lyon had a confrontation with a Fremantle fan on the way to the four-goal loss to Sydney.

But Lyon’s far bigger problem was the inability to curb Franklin, who kicked three goals in the 13.15 (93) to 10.9 (69) win.

A scan will decide the finals fate of Swans veteran Nick Malceski after he was subbed off with a hamstring injury.

On Friday night, Hawthorn opened the finals series with a powerful 15.14 (104) to 10.8 (68) qualifying final win over their arch-rivals Geelong.
