JAY Schulz kicked a club record-equalling eight goals in Port Adelaide's 72-point defeat of the Western Bulldogs at Adelaide Oval.

Port were dominant in the second half, to win over the Bulldogs 19.14 (128) to 8.8 (56).

Schulz is only the second Port player to kick eight in a match, following Warren Tredrea's bag against Carlton in 1998.

Schulz kicked four goals in the last quarter and is the outright leader in the Coleman Medal.

Saturday's win is the first time Port have beaten the Bulldogs since 2006, ending a seven-game losing streak.

Robbie Gray and Ollie Wines also starred for Port through the midfield and Alipate Carlile was rock-solid in defence.

A week after their major upset win over Collingwood, the Bulldogs fell away badly after a strong start.

It was also a painful trip to the "Portress" for the Dogs, with captain Ryan Griffen (back spasms), defender Jordan Roughead (shoulder) and key forward Jarrad Grant (broken nose) all hurt.

Bulldogs veteran Daniel Giansiracusa was booked for rough conduct after a late bump on Jared Polec at the start of the last quarter.

Leading by 12 points at half-time, the Power broke clear with six goals to one in the third term.

Wines led the onslaught with 13 disposals for the quarter.

Port started the game impressively with a coast-to-coast goal, but the Bulldogs were winning more of the ball early.

After four missed shots, the Dogs kicked two goals and opened up a 16-point lead.

The Power hit back with the last two goals of the opening term and the first of the second to take back the lead.

As the Dogs lost Griffen and Roughead to injury, Port took control and opened up a two-goal lead at the main break.

Roughead was able to return, but Griffen was subbed out at half-time.

Roughead then landed heavily in the third term, hurting his shoulder again, forcing him out of the game as well.

Contested ball is normally the cornerstone of the Bulldogs' game, but after their promising start they were outworked badly.
