PORT Adelaide has lost by 56 points to St Kilda in a dour affair at AAMI Stadium on Sunday.

The Saints kicked two goals in the first 90 seconds of the game, including one to skipper Nick Riewoldt from a free kick before the opening bounce, to take an early lead and were never headed, posting their highest score of the season to record a comfortable 17.7 (109) to 8.5 (53) victory.

St Kilda coach Ross Lyon didn't learn much about his team in a game it was expected to win, and win well, but he would have taken heart from the continued resurgence of Riewoldt.

The out-of-sorts forward rediscovered form and much-needed confidence, kicking three goals in the third quarter against North Melbourne last weekend, and built on that performance against the Power.

He kicked 4.2 opposed to Jackson Trengove and Troy Chaplin, posting his best return since booting seven goals against the Kangaroos in round 20 last season.

Ex-Geelong recruit Ryan Gamble also bagged four goals, equaling his previous best return against the Western Bulldogs in round 16, 2008, and kicking multiple goals for the first time as a Saint.

There were spotfires all over the ground in the first half.

Sam Fisher and Chad Cornes, playing his first game since round six, engaged in a push and shove in the opening term, and Danyle Pearce earned a free kick in the second quarter after being thrown into the fence by Brendon Goddard.

The simmering tension culminated in a melee involving more than a dozen players, including combatants Cornes and Fisher, and pests Stephen Milne and Tom Logan, in the third term.

Unfortunately for the Power, they couldn't channel their aggression into hard running and strong defensive pressure.

They matched the Saints in the contested possession count, but turned the ball over too often.

Experienced players Kane Cornes, Travis Boak and Troy Chaplin all committed basic skill errors, which resulted directly in goals to St Kilda.

Promising onballer Hamish Hartlett, who amassed 32 possessions (16 contested) and seven marks playing again as a half-back flanker, was one of few positives for the home team.

Prior to Sunday, the Power had at least been competitive in patches during their four-match losing streak, but appeared flat from the start against the Saints.

St Kilda dominated the inside 50 count 14-1 in the opening quarter, kicking four goals to Port's one to lead by 18 points at the first change.

A goal to Jay Schulz cut the margin to 13 points early in the second quarter, but the Saints kicked the next four goals to increase their lead to 31 points at half-time.

The Power failed to score a goal in the third term to register their second goalless quarter in two weeks, and two consolation goals to substitute Cameron Hitchcock in the final quarter saw them narrowly avoid their lowest score of the season.

Port Adelaide's loss was compounded by an arm injury to Trengove.

Trengove's wrist swelled up after Riewoldt trod on it in the final quarter, but the club was optimistic the defender had sustained a ruptured blood vessel and not a break.

Influential players
Hartlett backed up his 27-possession game against the Brisbane Lions last weekend, with his best game in Port Adelaide colours on Sunday. The Power's highest-ever draft pick (No.4 in the 2008 NAB AFL Draft) gathered a career-best 32 touches (16 contested) and seven marks in a classy display across half-back. Robbie Gray enjoyed more time in the midfield against the Saints, amassing an equal-career high 26 possessions, eight tackles and six clearances.

Key match up
Another Port Adelaide player, who could claim to having won his position, was Chad Cornes. Cornes played a negating role on Fisher, limiting the prolific possession-getter to his worst return (10 disposals) since round seven, 2010, when he was tagged out of the game by Carlton utility Ryan Houlihan. Cornes had a modest return of 11 possessions, but received a cheer from the adoring Power faithful with each touch.

What it means
Port Adelaide needs to win five of its last seven games to avoid recording its worst season in history, and is only percentage ahead of newcomers Gold Coast in 16th place on the ladder. The club's younger players are tiring and the team is still unable of put in a four-quarter performance.

What the coach said:
Matthew Primus (Port Adelaide): "They had us on the back foot from the word go. It wasn't until the last quarter that anything, statistically, looked like going our way, but by then it didn't matter, the game was dead and buried. Their ability to dominate the stoppages and really get all over the top of us in the first quarter set the tone for how they wanted to play. That [St Kilda] team has been a pretty good one for the last two or three years and we came up well short against them today."

Toyota AFL Dream Team highlight
Port Adelaide: Hamish Hartlett ($311,900) may be carrying a troublesome left shoulder, but he continues to fight hard for Port with a courageous 109-point performance against the Saints.

Quarter-by-quarter summary
First quarter
The Saints made the earliest of statements against the Power in the opening term. In one of the quickest goals in AFL history, Nick Riewoldt slotted a set shot three seconds into the match after receiving some extra attention from Port's Jackson Trengove before the start of play. Another to Leigh Montagna gave the visitors a two-goal break just two minutes into the game, much to the frustration of the Port Adelaide faithful. Intermittent rain and a gusty breeze made it tough for both teams with skill errors aplenty in the slippery conditions. A long goal to Robbie Gray gave the Power some respite midway through the term, but St Kilda looked far more dangerous in attack as Riewoldt added another at the 25-minute mark. The Saints had 10 more inside 50s and nine more clearances for the term to take an 18-point advantage into the first change.

Second quarter
Jay Schulz continued his hot form following on from a seven-goal haul last week, nailing his first early in the second term after a strong contested mark in the goalsquare. But Ben McEvoy rucked and roved at the next centre bounce to put the visitors right back into attack, where Ryan Gamble converted for the quick reply. The blustery conditions continued to cause havoc on the players' skill execution, with plenty of stoppages and scrimmages marring the second term. Most of the play was still centred in the Saints' forward line, as the visitors kicked away with goals to Steven, Milne and Riewoldt. The Power rallied with consecutive goals to Schulz and Stewart, however their good work was undone after a terrible turnover from Travis Boak led to Gamble's second goal for the term. St Kilda looked in total control with a 31-point buffer at half-time.

Third quarter
Conditions improved somewhat after the main break however the match remained on St Kilda's terms, with Riewoldt booting his fourth goal of the match in the early minutes. Port showed a fiery intensity and tried to unsettle the rampant Saints, sparking a mini melee involving a cluster of players at Port Adelaide's half-forward line. But St Kilda retained its focus, as skill errors continued to riddle Port Adelaide's game. The Power were simply outclassed by the visitors, managing just two behinds for the quarter. A howling turnover from Troy Chaplin typified Port's woes, gifting Nick Dal Santo (30 possessions to three quarter-time) the easiest of goals as the visitors cruised to a 50-point lead at the final change.
Port Adelaide 4.4 (28) St Kilda 12.6 (78)
 
Fourth quarter
Cameron Hitchcock's goal was Port's first since the 27-minute mark of the second term, but it was futile resistance against the charging Saints. Ryan Gamble lifted his tally to four goals with another in the final term to equal his career-best effort, as Nick Dal Santo finished with 36 possessions and two goals in a best on ground performance. A late incident involving David Armitage and Matt Thomas may come under scrutiny from the match review panel in the only souring note for the Saints. The 56-point pasting moves St Kilda just one game outside of the top eight.
