Adelaide’s Riley Thilthorpe has dominated a record 98-point belting of arch foe Port Adelaide which lifts the Crows to top spot on the AFL ladder.

Thilthorpe booted three goals in a 20.13 (133) to 5.5 (35) victory on a sodden Saturday night at Adelaide Oval.

The margin was the biggest in Showdown history and consigns departing Port Adelaide coach Ken Hinkley to an unwanted record in his final season.

It was also the biggest loss of his coaching career.

He cut a dejected figure as he walked off the field following the post-match presentations.

The long-time coach now has four matches remaining before he bows out.

The Crows will sleep on top of the ladder, though Collingwood will likely re-take pole position on Sunday with a win over Richmond.

Adelaide will finish the round no lower than second after logging five consecutive victories for the first time under sixth-year coach Matthew Nicks.

The sole blemish on Saturday night was a hamstring injury to Max Michalanney, who was substituted in the third quarter.

The 201cm-tall Thilthorpe defied the heavy rain with his influential 19-disposal display featuring six clearances, and veteran Taylor Walker and Ben Keays booted three goals each.

Adelaide’s Jake Soligo (35 disposals) and Sam Berry (20 touches) scored two goals each.

On-baller James Peatling (26, one goal) and captain and 150-gamer Jordan Dawson (21, one goal) were also prominent, while Mark Keane and Josh Worrell ruled in defence.

The Power slumped to an 8-11 win-loss record and added another player to their lengthy injury list with Lachie Jones substituted because of a corked thigh.

Port vice-captain Zak Butters (34 touches), Ollie Wines (25) and skipper Connor Rozee (22) battled against the tide while Jed McEntee kicked two goals.

The match began bizarrely when Port’s Miles Bergman roved the first bounce and launched a 50 metre kick - the wrong way.

Adelaide’s Darcy Fogarty marked the Bergman blunder and missed the set shot, but his side enjoyed early control.

The Crows created an ominous 3.6 to 0.1 lead before Port hit back with three consecutive majors of their own - a stunning McEntee shot from a boundary line reduced their deficit to five points at quarter-time.

Adelaide then produced a game-breaking burst, scoring four goals to none in the second stanza as Thilthorpe took control.

The big Crow scored with an audacious 50m left-footer on the run as Adelaide crafted a 29-point half-time advantage, 7.8 to 3.3.

Thilthorpe had 14 disposals, his eye-catching goal and six clearances for the half and extended his influence with the opening goal of the third quarter.

The strike was the first of five goals to Port’s two for the term as Adelaide led by a whopping 50 points at three quarter-time, 12.11 to 5.3.

And Thilthorpe again took centre stage with the initial goal of a last term when Adelaide piled on eight goals to nil to cruise to victory and a 30-28 overall record against Port.
