Reigning premier Geelong's 47-point hammering of West Coast has been soured by a suspected broken wrist to goalsneak Tyson Stengle.
Jeremy Cameron, Tom Hawkins and Brad Close kicked four goals each in Geelong's 21.10 (136) to 13.11 (89) victory.
Stengle faces a stint on the sidelines after his left wrist was pinned in a Josh Rotham tackle just before halftime in Sunday's Gather Round fixture at Adelaide Oval.
Stengle's injury put a dampener on the Cats' second win of the season, which featured a devastating burst of a dozen consecutive goals.
West Coast began brightly, kicking the initial two majors and recording eight inside 50s to one inside 10 minutes.
But the tide sharply turned and the Cats kicked the next 12 goals.
Attacking aces Cameron, Hawkins and Close feasted and Mark Blicavs and Ollie Henry scored two majors each.
Defender Esava Ratugolea grabbed nine marks and stalwarts Tom Stewart (24 disposals), Patrick Dangerfield (23), Isaac Smith (23, one goal) and Cam Guthrie (22) were chief ball-winners.
West Coast's Jake Waterman and Oscar Allen both slotted four goals, Jack Darling kicked two, Jamaine Jones gathered a match-high 25 touches and Tim Kelly had 22 disposals against his former club.
But the Eagles were blown away after their promising start as Geelong ruthlessly flexed their collective muscle.
Hawkins took the spotlight in the first term, scoring two goals and setting up another, to help create a 5.3 to 2.3 quarter-time lead.
After Hawkins increased the margin with his third goal just 25 seconds into the second term, Cameron slotted three in four minutes.
Cameron's purple patch came in a lopsided stretch when the Cats added 70 points to West Coast's one, with first-season Eagle Reuben Gibney finally breaking his side's goal-less spell to end Geelong's run of 12.
But Cameron instantly replied with his fourth of the second quarter, as the Cats finished with nine for the term for a 64-point halftime lead, 14.5 to 3.7.
The damage was done, though West Coast outscored the Cats with 10 goals to seven in the last half.
Remarkably, the Eagles' heavy defeat wasn't the worst for the club this weekend: their WAFL side suffered a 169-point hammering from West Perth on Saturday.
