PORT Adelaide coach Ken Hinkley says his side must learn to compete over four quarters after being overrun in the final term by a dominant Fremantle outfit on Saturday.

The Power were one-point ahead at three-quarter time but failed to hit the scoreboard in the final quarter, as the Dockers romped home to a 21-point victory.

Fremantle had 15 more inside 50s and won 12 more clearances in the final term, which Hinkley said was unacceptable.

"The last quarter was dominant by Fremantle. They had the run in their legs at the end of the game that we couldn't provide," Hinkley said.

"They just controlled the territory (of) the game. We never really had any looks at it in the last quarter … it didn't feel like at any stage in the last quarter (we would) get a run at it."

Hinkley said his team needed to learn from their final quarter fade-out and use it as an opportunity to improve.

"We had another chance to win … we were level enough at three-quarter time and we just have to learn from every opportunity we get," he said.

"It was one of those days to be unhappy about a quarter that hurt us badly."

While Fremantle star Michael Walters was the match-winner, the Power were well served up forward by youngster Kane Farrell, who kicked 4.1.

Hinkley said Farrell's performance indicated his immense potential to be a future star of the competition.

"He has some AFL traits that are really important. He has some speed and a great finish," Hinkley said.

"Walters (did) something similar at the other end and we look at a very young Kane Farrell and think and hope at one stage of his career he may be able to do some of those sorts of things in big games as well."

The Power are set to be bolstered in coming weeks by the return of Charlie Dixon and Ollie Wines, with both coming back from injury through the SANFL.

Hinkley said he expected them to soon force their way back into the AFL side.

"We've got some quality names in those teams and we like to think they'll push their hands right up in the air," he said.

"Regardless of today's result, we would expect that those players would play well and push their way back into the team.

"We don't rush them just because of winning and losing."
