Dynamic Chad Wingard kicked five goals as Port Adelaide overran Fremantle for an 18-point win to take outright top spot on the AFL ladder.
Wingard was the game-breaker as Port triumphed 13.16 (94) to 11.10 (76) in Saturday’s Adelaide Oval encounter.
Port banked their seventh victory from eight games – their best-ever start to an AFL season.
The Power trailed by five points at three-quarter time but produced a customary fast finish which floored the Dockers.
Wingard kept the Power in the contest with his uncanny goal-kicking before the home side steamrolled Freo with five goals to two in the final term.
Matthew White kicked the first two goals of the last quarter and utility Kane Mitchell also finished with two majors.
Port midfielders Ollie Wines (27 disposals), Robbie Gray (30 touches), Travis Boak (29 possessions) and backman Jasper Pittard were prominent.
Fremantle goalsneak Matt De Boer booted three goals, all in the first half – a return matched by versatile Zac Clarke.
And Freo onballers Nat Fyfe (34 disposals, two goals), David Mundy (31 possessions) and Lachie Neale (28 touches) were influential.
But the Dockers lost Stephen Hill to a left knee injury, the midfielder substituted early in the third quarter as his injury-troubled season continued.
And his teammate Paul Duffield faces possible suspension for a head-high bump on Wingard midway through the second stanza.
Duffield collected Wingard after the Port star disposed of the ball in a bump certain to be scrutinised by the match review panel.
Wingard was stunned but remained on the field – and Port were thankful, given he kicked four of the home side’s next five goals.
In his 50th AFL game, Wingard also took a last-term screamer as Port unleashed a withering final-quarter surge to dismiss the Dockers, now with four wins and four losses.
