Coach Ken Hinkley has lauded Port Adelaide's ruthless streak in a record 75-point demolition of a hapless Adelaide on Saturday night.
Young guns Xavier Duursma (three goals), Zak Butters and Connor Rozee all fired in the Power's 17.8 (110) to 5.5 (35) victory at Adelaide Oval.
The winning margin is Port's highest against their arch foe and they restricted the Crows to their lowest total in 48 clashes of the South Australian rivals.
The Crows crumbled under Port's manic pressure which Hinkley labelled a highlight.
"I didn't know it was a record margin, but it's always nice to win Showdowns," Hinkley said.
"When you win and when you big, I know the group were committed to that at three quarter-time. It was 'let's keep going'."
Adelaide's grim night was compounded by captain Rory Sloane suffering a corked thigh and defender Jake Kelly being concussed in the first quarter.
"It's a really embarrassing performance," Crows coach Matthew Nicks said.
"It's a disappointing day for us but hopefully one we learn from."
Port's emerging quartet Rozee (17 disposals, one goal), Duursma (three goals) Butters (21 touches, one goal) and Todd Marshall (two goals) were instrumental as the Power banked consecutive wins to open the stop-start season.
And seasoned campaigners Travis Boak (24 possessions), Justin Westhoff (three goals), Charlie Dixon (three goals) and Steven Motlop (24 disposals, two goals) were also dominant.
Motlop launched himself onto the shoulders of Crow Paul Seedsman for an early mark of the year contender, and goaled from his following kick in the third term.
The Crows had no clear winners, with Matt Crouch (26 touches) and his brother Brad (25 disposals) their prime ball-winners.
Adelaide started strongly, with Sloane and key forward Darcy Fogarty scoring goals inside nine minutes but they managed just three more majors for the game.
The Power booted four consecutive goals and led by 32 points at halftime before creaming the Crows with six goals to one in the third quarter.
The crowd of 2240 people, the first club members allowed into an AFL game this season, was pro-Port.
As a Port home game, they had 1475 members while the Crows had 475 members attending, with the rest in corporate boxes.
The Power faithful had much to cheer about - Port's previous biggest win over the Crows was 65 points in 2001, while Adelaide's previous low score against their home-town rival was 5.14 (44) last year.
The bitter SA rivals now travel to a Gold Coast hub where they will both be housed at the same golf resort for at least the next three rounds.
