Sydney has handed West Coast the biggest loss in club history, thrashing the Eagles by 171 points at the SCG on Saturday.
It was a bloodbath from the Bloods, who piled on 31.19 (205) to the Eagles' 5.4 (34), as nine Swans kicked multiple goals.
The Swans started strong, kicking nine goals in the opening term to West Coast's solitary major from Oscar Allen.
The Eagles showed fight in the second stanza - led by ferocious skipper Luke Shuey and midfield colleague Tim Kelly - booting three goals to Sydney's five to stem the bleeding somewhat.
But the floodgates opened in the third term with the Swans enjoying an 11-goal third quarter to head into the final break with their highest three-quarter time score in club history.
Isaac Heeney led an impressive forward line, kicking five goals from 22 disposals, while Errol Gulden's attacking run from the middle was a highlight, with three goals and 32 disposals.
Allen and Jack Darling both kicked two goals for the Eagles on a dirty day at the SCG when the Swans registered 77 inside 50s to the visitors' 34.
The aggressive rebounding Swans of 2022 were back, albeit aided by a lethargic Eagles outfit.
Sydney looked to move the ball with speed through the corridor and delivered inside 50 with more clarity than the side has been able to produce in recent weeks. It dominated the stats sheet, including the clearances (49-36) and disposals (441-300).
A lack of chemistry in the ever-changing Eagles line-up was clear early in the game, as all too often were they thwarted by an inability to make space for one another or acknowledge a teammate's superior positioning.
West Coast did start to find more connection in the second quarter, putting together some neat end-to-end passages of play thanks to its running in waves and pinpoint handballs. As a result, it was able to put through three goals for the quarter.
It was short lived, however, as the Swans were ruthless, slamming home 18 consecutive goals between the second and final quarters.
Eagles captain Luke Shuey (eight tackles, 28 disposals) worked tirelessly all game, Tim Kelly (27 disposals, seven clearances and a goal) tried to get things going at the source, and Elliot Yeo (10 tackles) brought some pressure in the face of the onslaught.
West Coast's injury woes continued, with second-gamer Jack Williams subbed out of the match before half-time.
