A dominant Taylor Walker has helped Adelaide down West Coast by 31 points to emphatically snap a five-game AFL losing streak.
The Crows, with Walker, Shane McAdam and Darcy Fogarty kicking three goals each, triumphed 13.10 (88) to 8.9 (57) on a rain-soaked Adelaide Oval.
Adelaide laid their victory platform with five goals to none in Saturday's opening term as the Eagles' miserable season continued.
West Coast remain anchored in last spot with a solitary win as their percentage dropped to 50.7.
Adelaide stalwart Walker was superb with his three goals complemented by 22 disposals, 10 score involvements and eight marks.
His fellow forwards McAdam and Fogarty also feasted on supply from a dominant midfield headed by Rory Laird.
Laird's game-high 33 disposals included a goal, six inside 50s and eight clearances and on-ballers Jackson Hately (25 touches), Matt Crouch (27) and Ben Keays (29) also revelled in the wet.
Defenders Brodie Smith (21 possessions) and Jordan Dawson (23) were other standouts as the Crows banked a fourth win of the season.
West Coast's Andrew Gaff (30 touches, one goal), Tim Kelly (25 disposals) and captain Luke Shuey (27 possessions, eight inside 50s) battled against the tide and Jack Darling kicked two goals.
Eagles stalwart Jeremy McGovern was a late withdrawal because of a back injury which caused him to be substituted out of last week's game, replaced by Luke Foley.
And McGovern's defensive nous was sorely missed by the visitors as the opening quarter turned into an Adelaide procession.
The Crows kicked 5.2, including two goals from Fogarty, before West Coast managed to score - a snap from Josh Kennedy in the 26th minute slid off the side of his boot for a point.
Adelaide led 32-1 at quarter-time before West Coast's Darling scored his side's first major early in the second term, only for the Crows to kick the next three goals to create a commanding 42-point advantage.
The Eagles' Darling and Gaff added goals but Adelaide logged four goals to three for the quarter for a 9.6 to 3.4 halftime lead.
West Coast managed to outscore their hosts in constant rain in the second half, scoring five goals to four goals, but the damage had been done.
