WITH 12 first-term possessions, Luke Dahlhaus led the Western Bulldogs' fast start against Port Adelaide on Saturday night.

The Bulldogs had nine scoring shots to six in the first quarter and, although they were unable to make the Power pay, Dahlhaus looked set for a potentially match-winning display.

He had 17 disposals to his name at the main break, but that's where his influence on the match ended.

Jarman Impey, Hamish Hartlett and Brad Ebert helped restrict the 22-year-old to just two possessions in the second half, while piling on 22 between themselves.

Dahlhaus didn't touch the ball while playing on Impey after half-time.

It was far from a one-man stopping job, but Impey told AFL.com.au restricting the Bulldogs star was crucial in the Power's 38-point win.

"The match up was that if Dahlhaus went forward I would grab him, so a couple of the boys had the job on him in the midfield," he said.

"We knew that he's been in great form coming into the game, he's one of their key players and he's very dangerous.

"He was one of their players that we kept an eye on – I think he had like 10 touches in the first five minutes and that's when he started to get a bit of attention."

Saturday night's win was Port's second straight victory, after its 61-point triumph over Melbourne in round nine.

The Bulldogs won more contested possession, narrowly won inside 50s and had more hit-outs, but the Power's stunning six-goal final quarter was an example of its potential strength.

In that last term the Power were plus-eight for contested possession and plus-28 for uncontested possession.

Impey was on the same page as his coach Ken Hinkley, believing that the Power's form was growing towards where it needed to be.

"It's slowly starting to build, we feel we can definitely improve and we have to improve just on a few key areas," he said.

"We're training well throughout the week and we've just got to keep improving."
