Port Adelaide have hammered a depleted Gold Coast by 115 points to hold a coveted AFL top-four spot -- for now.
Power forward Sam Gray kicked six goals in Saturday night's 20.15 (135) to 3.2 (20) victory.
The Suns' meagre total is a club-record low.
Port's massive margin -- just two points shy of equalling their biggest win in the AFL -- lifted them to fourth, a ladder slot held by three clubs on one day.
Richmond started there, then Sydney took it before Port -- though the Tigers can reclaim it entering the finals by beating St Kilda on Sunday.
Gold Coast's miserable 20-point tally is less than their previous low of 34 points against the Western Bulldogs in 2012.
The Suns didn't score for two entire quarters in a display which threatens the chances of interim coach Dean Solomon keeping the job next season.
"Over the next week or two I will get some fresh air and have a think," Solomon said of whether he would pitch for the role.
Solomon hoped the loss would prove to be a "defining moment" for his club by providing motivation to improve.
"We expect a lot more than that," Solomon said.
"They (Port) showed us what a top-four side looks like.
"We fell away and we can't sustain the brand of footy that we are trying to play.
"We can't ignore tonight, we have got to take it on board."
Gold Coast's troubled season ends in 17th place and the prospect of losing megastar Gary Ablett to Geelong.
The Suns were missing 13 injured players -- mainly from their top shelf, including Ablett -- and were scoreless from 26 minutes into the first quarter until the first minute of the final term.
Gold Coast's Matt Rosa (24 possessions), Pearce Hanley (22 disposals) and Jarrod Harbrow (24 touches) battled gamely and Peter Wright kicked two goals but Port tuned up in style for their first finals campaign in three years.
Power livewire Gray was the chief scoring source and ex-Sun Charlie Dixon booted four goals, while Ollie Wines (32 disposals), Darcy Byrne-Jones (25 touches), Travis Boak (24 possessions) Chad Wingard (20 touches) were influential.
"We are in pretty good shape," Port coach Ken Hinkley said.
"We have played some good, strong footy in the last three weeks."
