Hawthorn has poured more misery on Adelaide's faltering season, leaving last year's losing grand finalist in serious danger of missing finals for the first time in four years.
James Sicily proved the circuit-breaker in a game lacking for aesthetics in the opening half, bookending and kicking three of seven straight Hawk goals in the third quarter.
Two of Sicily's finishes – celebrated with gusto – were wonderfully struck kicks outside 50m and the other was from barely inside the arc to transform a dour struggle into a 56-point rout.
Each side managed a paltry three majors in the first two terms – compared to a combined 14 behinds – but Hawthorn's scoring surge after half-time viciously put Adelaide to the sword.
The Hawks held the Crows scoreless for the term, just the seventh time in club history they failed to register a point in an entire quarter.
A four-point half-time buffer blew out to 48 at the final break and eventually became a 12.16 (88) to 4.8 (32) Hawthorn triumph that has it only outside the top eight on percentage.
The biggest roar was saved for four-time premiership player Shaun Burgoyne, who capped his 350th match with a brilliant
It was an important result for the Hawks, who narrowly avoided a fourth consecutive loss with a last-start three-point win over Port Adelaide after trailing by 24 in the opening term.
Alastair Clarkson's men, fresh from the bye, destroyed Adelaide in the clinches in the pivotal third quarter, easily winning clearances (18-1) and contested possessions (37-23).
Don Pyke's team has now suffered four defeats in a row for the first time since dropping six on the trot between rounds nine and 14 in 2011, to slump from the top four to 11th.
"It was a really poor performance," Pyke told reporters.
"The Melbourne performance about a month ago was disappointing, but tonight we came here with really high hopes and expectations.
"To perform that way, given at half-time we recognised the game was tight and a genuine arm-wrestle, our contest work and our defensive work in that third quarter
Adelaide missed All Australian Rory Laird (broken hand) badly, with stagnant ball movement plaguing its effort all night.
Bryce Gibbs (28, six clearances) did all he could to keep the Crows afloat, but had little support, although Jake Kelly hung tough as part of an under-siege backline.
Adelaide should regain Laird after next week's bye, along with Riley Knight (hamstring tendinitis), Tom Lynch (side strain) and Rory Sloane (foot).
MEDICAL ROOM
Hawthorn: The Hawks lost key defender James Frawley shortly before the first bounce because of a migraine. The same problem saw him sit out the second quarter against his former sider Melbourne in round four.
Adelaide: Sam Gibson left the ground in the second quarter with a left hamstring issue. The once-durable Kangaroo played 130 straight games before being a late withdrawal from the Crows' round one side with a hamstring injury. Gibson returned to the field in the third term after a rigorous fitness test. But Paul Seedsman struggled with a right hip problem late in the contest.
NEXT UP
Hawthorn plays the third of its four matches this season in Launceston next Saturday against a suddenly upbeat Gold Coast, which has beaten the Hawks the past two times they met. The Crows have the chance to reflect during their bye before hosting West Coast at Adelaide Oval on Saturday, June 30.
