West Coast may be the closest thing the AFL currently has to roadkill, but Port Adelaide still took plenty of mileage from a 36-point victory at AAMI Stadium that keeps them clinging onto the fringes of the league's top eight.

On a sun-drenched winter afternoon Port rebounded from a deflating loss to Melbourne by beating the Eagles 17.10 (112) to 11.10 (76), leaving the Eagles still winless away from home across 19 matches since 2007.

Port had many winners on the day and it was difficult to separate captain Domenic Cassisi and young midfielder Jason Davenport for best afield honours.

Davenport's first quarter effort - 12 disposals, two goals, three assists and four tackles - was remarkable, while Cassisi fought for everything and notched no fewer than 14 tackles.

Up forward Warren Tredrea, Brett Ebert, Robbie Gray and Nick Salter were all dangerous, while Jacob Surjan did a fine job in defence on Eagles goal-sneak Mark LeCras.

"The club was under a lot of pressure this week so it was fantastic that we really came out of the blocks fast," Power coach Mark Williams said.

"I thought Jason Davenport started the game brilliantly and had a lot to do with where we were at halftime and Dom Cassisi continues to shine from the front.

"It was (Davenport's) best game for the club, he's a fantastic, enthusiastic guy, but I think ... he doesn't really believe in himself.

"So for him to get little glimpses of this to say 'wait a minute, I can do this stuff' was great for him."

Eagles forwards Ashley Hansen and Quinten Lynch worked hard against the tide, and Chris Masten had plenty of the ball.

West Coast's one and only victory over the Power in Adelaide came in 1998 and they never really looked like adding to it despite a spirited start.

Lacking the superior ruck/rover tandem of Dean Cox and Daniel Kerr, the Eagles made niggle their focus in the early exchanges, paying particular attention to tag-shy Port winger Danyle Pearce.

Though it had the desired effect on Pearce - he battled through another quiet game - the Eagles were outpointed virtually everywhere else.

Youngster Patrick McGinnity's freakish running snap gave the Eagles the first goal of the game but their time in front was brief, Port's forward line proving varied and dangerous on the end of a sustained superiority in midfield.

Davenport's first term pyrotechnics played a large part in establishing the flow of the game, while Cassisi maintained admirable intensity as he has for most of the season.

Tredrea, Ebert and Justin Westhoff - who was laid flat on his back by a crunching bump from Darren Glass in the second - all proved damaging in attack to set up a 47-point margin at the main break.

The second half unfolded without any significant changes to the script, the Eagles hapless away from home and the Power doing most things well.

West Coast salvaged a little pride by winning the final quarter, but they did so without ever having a chance to claim the match.

"It's not ideal and it's something we want to turn around and we're working hard on doing that," Eagles coach John Worsfold said of his club's horrid away record.

"The first quarter was very disappointing and the players have worked very hard on going out ready to start the game, but there's obviously things we need to do better."
