The Crows led by 22 points at half-time, but experienced a few nervous moments in the third quarter as the Power slashed the margin to just 11 points.
Young star Rory Sloane steadied for Adelaide with a long goal on the run late in the third term, and enigmatic forward Taylor Walker slotted three of the next four goals to break Port Adelaide's spirit and ensure an important 16.15 (111) to 11.13 (79) win in an emotion-charged week for the Crows.
It was the seventh time in the last 11 instances a caretaker coach has won in his first game in charge.
The result was a significant turnaround for the Crows, who recorded a record-low score of 3.6 (24) in their 103-point loss to St Kilda only nine days earlier.
Nathan van Berlo played a typical 'captain's' game, amassing 30 possessions and taking out the Showdown Medal for best afield.
Walker, playing his first game since straining his knee against the Brisbane Lions in round 10, thrived in the absence of injured full-forward Kurt Tippett, booting a game-high four goals.
The loss was further marred by injuries to in-form forward Jay Schulz (foot and back), defender Jackson Trengove (knee) and Tom Logan (foot).
All eyes were on the Crows in the first quarter to see how they would respond to the sudden resignation of long-serving coach Neil Craig on Monday.
The contest between the 14th and 17th-placed teams on the AFL ladder wasn't pretty, with both the Crows and the Power committing basic skill errors, but it was willing.
Adelaide defender Graham Johncock set the tone by running through Port Adelaide forward Cam Hitchcock in the first term, while Showdown 'specialist' Chad Cornes tried to inspire his team by antagonising the Crows midfielders, and giving a trademark fist-pump to the crowd after kicking a goal in the third quarter.
Predictably, Adelaide started well, kicking five of the first six goals of the game.
Schulz did his best to lift the Power with two goals and a soaring mark over Brent Reilly in the second quarter, but the Crows kicked further ahead through solid contributors Sloane, Matt Wright and Jack Gunston.
The two teams went goal for goal early in the third quarter, but Port Adelaide couldn't bridge the gap and the Crows kicked away in the final term.
Influential players
Travis Boak (29 possessions) was the standout for the Power, while Schulz was instrumental before being injured.
Final farewell?
Chad Cornes, who is tipped to announce his retirement this week, played Showdown XXXI as if it were his last, booting 2.2 from eight marks. The player the Adelaide faithful love to hate received boos from the crowd with each of his 13 possessions, but his passion and presence has been pivotal to establishing and maintaining the rivalry between the Crows and the Power over the last decade. The Adelaide fans might not miss him, but the Showdown contests will.
What the coach said
Matt Primus (Port Adelaide): "It's too far off what our best is capable of and a long way off what it needs to be AFL standard. All year we just haven't played like footy means the absolute world to us. In the end, we deserved the result we got."
Toyota AFL Dream Team highlight
Port Adelaide: Cam Hitchcock ($176,000) was a livewire up forward for the Power, finishing with 90 DT points and three goals next to his name. The 21-year-old goalsneak has now kicked seven goals in his past three games.
QUARTER BY QUARTER SUMMARY
First quarter
The heat was on early with both teams looking to make a statement in what has been a forgettable season for both clubs. There was plenty of niggle off the ball, and when Adelaide's Graham Johncock ironed out Port's Cam Hitchcock, it was clear both sides were set for a bruising afternoon. Showdown specialist Chad Cornes opened the account for the Power with his first goal in the early minutes, but from there the Crows took control. Taylor Walker made something of nothing with a clever goal off the deck, followed by goals from Andy Otten and Jack Gunston to give Adelaide an 11-point lead at the 17-minute mark. The fierce tackling pressure of both clubs was a highlight, with 31 tackles laid in a physical opening quarter.
Adelaide 3.4 (22) Port Adelaide 1.5 (11)
Second quarter
The Crows picked up where they left off after the first break, with a thrilling dash from Patrick Dangerfield setting up Gunston deep inside 50. But the young Crow was denied his second goal with a desperate tackle from Port's Troy Chaplin. Adelaide eased out to a handy 22-point margin with successive goals to Matthew Wright and Rory Sloane, before Jay Schulz marked strongly and kicked a goal to break Adelaide's five-goal run. The Power's wayward finishing was preventing a Port revival, with misses to Hamish Hartlett and Chad Cornes proving costly. Schulz's hanger late in the term provided a highlight for the Power, with his effort keeping his side within four goals at the major break.
Adelaide 8.7 (55) Port Adelaide 4.9 (33)
Third quarter
Quick goals to Justin Westhoff and Brett Ebert reduced the margin to 11 points within the first five minutes of play. But in a cruel twist for Port, Schulz was subbed off after injuring his left hamstring in a tough marking contest. Chad Cornes produced another Showdown moment, plucking a one-hander in the goalsquare and slotting his second goal to put the Power back in it. But the momentum continued to swing, with a classy running goal to Sloane and a set-shot score to Walker extending the margin to four goals once again. Adelaide continued to get to the ball first, leading the clearance count by 18 at three-quarter time. Walker booted a third after the siren to put the Crows in a commanding position at the final change.
Adelaide 13.10 (88) Port Adelaide 9.10 (64)
Fourth quarter
Walker drove another dagger into Port's chest, booting his fourth goal early in the final quarter after a smooth transition from the Crows out of defence. A late hit from Cameron O'Shea on David Mackay sparked an old-fashioned Showdown melee, with plenty of willing participants including Chad Cornes and Chris Knights throwing their weight around. Mackay's resulting goal iced the game for Adelaide, with the final 32-point margin not necessarily reflecting the tone of the contest.
