PORT Adelaide used the premiership quarter on Thursday night to make its biggest statement yet in a record 11-game winning streak, underlining its flag credentials with a powerful burst against Geelong that set up a 38-point win at Adelaide Oval.

Jumped by the reigning premiers early and forced to come from 21 points behind, the Power flipped the game on its head with a brutal seven-goal run in the third quarter that sounded a loud warning to their rivals.

They then weathered a brief rally from the proud Cats early in the final term before slamming on another four unanswered goals to win 16.14 (110) to 11.6 (72) in front of a roaring home crowd.

The win further strengthens the Power's charge for a top-two finish, with Ken Hinkley's team moving to 12-2 and looking close to unbeatable in the second half of the season.

The result also makes Geelong's task of backing up its 2022 flag tougher, with the ninth-placed Cats now in a scrap to finish in the top eight with their 6-7 record, and skipper Patrick Dangerfield finishing the game under duress after suffering a heavy knock in a marking contest. 

They were made to look second-rate through a third quarter that saw Port dominate clearances (14-6) and inside 50s (14-9), ramping up their pressure and overwhelming the Cats.

Their ability to turn clearances into scores, which has been a major strength this season, was phenomenal as tall forwards Jeremy Finlayson (four goals) and Todd Marshall (three) capitalised.

Forward Sam Powell-Pepper (two) was also outstanding, while half-back Dan Houston continued a terrific season with 31 disposals and six clearances.

As good as they were after half-time, Port has rarely looked as sluggish during its winning run as it did in the opening quarter, getting caught on the back foot by Geelong. 

The Cats were slick on the outside and dominated uncontested ball (62-29) as they raced to a 20-point lead on the back of some brilliance from Gary Rohan, who kicked three of the first five goals of the game.

The premiership Cat leapt over ruckman Scott Lycett and then tall defender Aliir Aliir to take contested grabs and set the tone for his team, which looked in total control at the first break.

The response from Port didn't take long, with the match reverting to a contested slog in the second term as the home team ramped up its pressure around the ball and started to control the stoppages.

Back-to-back goals through former Cat Quinton Narkle, who was making his Power debut as a mid-season recruit, and Finlayson cut the half-time margin to just seven points.

The Cats still had reason to believe they were in control of the contest, but it wouldn't last, with Powell-Pepper launching the Power's seven-goal run early in the third term with some magic from the pocket, gathering at pace and dribbling the ball through with the outside of his right boot.

A stoppage domination ensured for the next 20 minutes as the Power's forwards lined up for their turn, with Finlayson's third goal deep in the quarter extending the lead to 30 points.

Geelong, to its credit, had one more effort to give and was able to cut the margin to 12 points early in the final term after premiership veteran Isaac Smith snapped on his left.

But their short run was quickly snuffed out by a Power team that showed its vast array of weapons might be even more dangerous than the competition suspected.

Mid-season recruit sparkles on debut 
Former Cat Quinton Narkle must have been pinching himself that he has broken into such a strong team just two weeks after being recruited in the Mid-Season Rookie Draft. Given his chance after Junior Rioli (illness) was withdrawn, the 25-year-old didn't waste it. He impressed with his attack on the ball early in the second quarter and was clever and poised with his disposal, finishing with two goals and 13 disposals. 

Power brute playing key role
Sam Powell-Pepper twice injected himself at key moments on Thursday night to kick goals that were worth their weight in gold. His brilliant first, hitting the ball at pace in the pocket, tapping it forward and then dribbling it home under pressure, got the Power rolling in the third quarter. His second, by contrast, came after he stood up in the tackle and threw Zach Guthrie aside, snapping the goal that ended a three-goal run for Geelong. It took the West Australian's season tally to 17 and kept him on track for a career-best return. 

Down night for Cats superstar
Geelong gun Jeremy Cameron was not his usual self on Thursday night, taking just one mark and finishing with 10 disposals and a goal. The premiership forward has slowed somewhat in the past month, kicking six goals across his past five games. Geelong coach Chris Scott looked to be rallying Cameron at three-quarter time for a lift. It was left to Gary Rohan to lead the forward line with his three early goals, but he also faded thereafter as the Cats' supply dried up, with the Cats losing the entries 44-24 after quarter time.
