Scott Boland claimed a spectacular triple wicket maiden to leave Australia on the brink of a 2-0 series victory over West Indies at the Adelaide Oval.
Mitchell Starc also claimed a wicket to leave West Indies on 38-4 in their second innings and needing an improbable 459 runs to avoid defeat on Sunday.
West Indies resumed play on day three on 102-4 and got off to a poor start when shining light Tagenarine Chanderpaul (47) was run-out by Starc.
Jason Holder (0) then edged Starc behind and, while Anderson Phillip (43) and Joshua da Silva (23) put together a 60-run seventh-wicket stand, the Windies soon faded again.
The tourists reached 214, and Australia then built up a seemingly unsurmountable lead as they posted 199-6 declared in their second innings and sent their opponents back in to bat.
Usman Khawaja top-scored with 45 off 50 balls for Australia, while Marnus Labuschagne (31), Steve Smith (35) and Travis Head (38 not out) all contributed in a rapid 31-over innings from Australia.
West Indies' opening batters were 15-0 off five overs when Smith brought in Boland, who took the wicket of Kraigg Braithwaite (3) off his first ball.
Boland then trapped Shamarh Brooks (0) in front with a ball that nipped back into the right-hanger from his third delivery, before snaring Jermaine Blackwood (0) with his sixth.
Chanderpaul did not fare much better as he was dismissed for a second time in the day three overs later for 17 when caught by Alex Carey off the bowling of Starc.
Labuschagne adds further misery
West Indies are winless in their past 18 Tests against Australia since 2003 and they have not had many – if any – worse days across that run than Saturday.
They lost 10 wickets for 150 runs across two innings, either side of Australia piling another 199, with Labuschagne's 31 taking him to 502 runs from his four innings – the sixth-most scored in a two-Test series.
Boland rips through Windies
Boland famously took 6-7 against England on his Test debut in last year's Ashes and he produced a display that was equally as ruthless here.
The 33-year-old, making just his fourth Test outing, claimed 3-9 off 5.2 overs bowled and now has a bowling average 9.81 for his 21 wickets.
