Three straight losses have left West Coast clinging to seventh spot heading into Sunday's western derby against arch rivals Fremantle.

West Coast's inaccuracy has proven costly this season, with the Eagles kicking a combined 23.39 in losses to Geelong, Port Adelaide and Carlton.

Kennedy has been one of the biggest offenders, with the 26-year-old booting 3.7 in the past fortnight.

The former Blue's twinkle-toe approach to set shots worked a treat last year as he bagged 60.23 for the season.

Kennedy has adopted a far smoother approach in his past two games, and while it hasn't paid dividends just yet, he said it was a necessary tweak in order to gain future success.

"It (the stutter) was just starting to put a bit of risk on my balance on the footy," Kennedy said on Monday.

"It probably evolved into something that was good at the time, but at this current stage I don't feel it's best for me."

West Coast players were left gutted after coughing up a 24-point lead in the final nine minutes against Carlton.

The Eagles sprayed 1.8 in the last term and Kennedy said their wayward goalkicking needed to be promptly addressed in order to keep their finals dreams alive.

"Being able to knock those goals over, especially in those dying minutes when they matter - we're not doing that at the moment," Kennedy said.

"The last two weeks have been pretty disappointing.

"If we had knocked Port over and we held that win against Carlton, we'd be sitting here at 5-1 and we wouldn't even be talking about these issues."

Fremantle defender Michael Johnson is free to play in the derby after he was offered a reprimand for bumping an injured Aaron Black in last week's loss to North Melbourne.

Goalsneak Hayden Ballantyne could also return for the Dockers, while West Coast will welcome back skipper Darren Glass from suspension.
