Port Adelaide’s unbeaten start to the AFL season continued with a 38-point win over Gold Coast on Saturday night.

The Power, who took control of the game with a nine-goal second quarter, notched their fourth straight win with the dominant 16.8 (104) to 9.12 (66) victory over the Suns.

Forward Jay Schulz lit up the second half with four goals for the visitors, including a second that came after a spectacular mark over the back of Sam Day.

In-form Justin Westhoff, youngster Hamish Hartlett and Chad Wingard all kicked three majors for the Power while Kane Cornes picked up an impressive 35 disposals and 16 marks.

Rory Thompson was the only multiple goalkicker on a tough night for the Suns.

Gold Coast, leading by seven points at quarter-time after captain Gary Ablett and Brendan Matera made strong starts, were unable to recover after continuing their trend of poor second-quarter efforts this season.

The Suns went into the halftime break trailing by 43 points after the Power booted nine goals to one.

It’s the fourth time in as many games the Suns have struggled to make an impact in the second term, giving coach Guy McKenna an obvious area to focus on.

The Suns, who lost young midfielder Harley Bennell before the game to a hamstring injury, had to call on sub Luke Russell early in the second term when Joel Wilkinson was unable to continue due to an ankle injury.

They also have a concern for Matt Warnock after he left the field with a shoulder injury while Ablett appeared to be struggling with a hand or wrist problem in the final term.
