FREMANTLE has overcome injuries to skipper Matthew Pavlich and clever forward Michael Walters to thrash Melbourne by 68 points at the MCG on Sunday.

The win put the undefeated Dockers one game clear on the top of the ladder after five rounds.

The Dockers won 18.10 (118) to 6.14 (50) after using the ball far more effectively after half-time.

They kicked seven goals to none in the final quarter to dominate the Demons.

Five talking points: Melbourne v Fremantle

Walters' injury occurred before quarter-time when he accidently ran into Lynden Dunn as he hunted the ball and then Pavlich clashed heads with Demons defender Colin Garland after marking just before half-time.

Melbourne also lost promising defender Christian Salem to concussion at half-time after Dockers' forward Matt Taberner cannoned into him just before the long break.

The Dockers' usual suspects dominated possession in the midfield, with Nathan Fyfe (30 disposals), Michael Barlow (32), Lachie Neale (25) and David Mundy (28) able overwhelm the Demons at stoppages.

Danyle Pearce was also impressive with two goals, 22 disposals and nine inside 50s.

The Dockers recorded 59 inside 50s to Melbourne's 39 but performed the basic skills much better after half-time to stretch the margin from 20 points to 68 points.

Dockers coach Ross Lyon said he was really pleased with the fast start and despite a few errors his team did the job he expected. 

"[It was a] dominant midfield performance, plenty of opportunities and I thought all divisions played their part," Lyon said. 

"I felt we should have been further ahead. I was a little bit frustrated. [In the] third quarter we had 16 entries and just slaughtered the ball a little bit and if you take away a 50, free kick off the ball and a slip over, they're probably three less goals." 

Fyfe didn't do his reputation any harm with his usual bullocking, brilliant performance although he spent significant time up forward.

He will still be in line for three Brownlow votes.

In Pavlich's absence, Chris Mayne stepped up with 12 tackles overall, kicking three goals (he finished with four) and taking four marks in the third quarter when he was most needed.  

At the other end, the experienced Luke McPharlin defeated Jesse Hogan comprehensively and seemed to unsettle the young forward at times.

The Dockers' early dominance around the stoppages upset Demons' coach Paul Roos, who gave his team a fearful burst at the first break.

The obvious conclusion was that he wasn't happy with the pressure being applied at the contest, and given the Demons had conceded the first four goals of the game his displeasure was reasonable.

The Demons responded with an excellent second quarter, only losing the term by one point and breaking even in the clearances.

At times they moved the ball with dare and looked an improved side despite not yet being in the Dockers' class.

However Roos was unimpressed with the effort of his team.

"They were five (goals) up (at three quarter time) and we played poorly and then we played worse in the last quarter," he said. 

"I don't think they had to play that well to beat us. We know they can play well. But you have to take your chances. You can't miss goals and you can't turn the ball over against a good team."

In his 100th game Jack Watts struggled and finished with just seven disposals.

More impressive was Angus Brayshaw, who had 16 disposals and kicked one goals, and key defender Tom McDonald who battled against the odds all day.

Jeremy Howe also tried hard, taking two spectacular marks and making a contribution at both ends of the ground while Jeff Garlett kicked three goals and looked dangerous at times.
