Nathan Lyon's late spell breathed new life into the second Test between Australia and the West Indies in Trinidad.
After a day marred by rain and dominated by Windies veteran Shivnarine Chanderpaul, Lyon claimed the second five-wicket haul of his Test career to give Australia hope of forcing a series-clinching win at Queen's Park Oval.
Lyon claimed 5-16 off a nine over spell to finish the day with 5-68, his second best Test haul after posting 5-34 on debut in Sri Lanka last year.
At stumps the Windies were 9-252, still trailing Australia's 311 by 59 runs in a day blighted by a 111 minute rain delay.
Chanderpaul and Narsingh Deonarine (55) had dominated the day, adding 130 for the fifth wicket before Lyon came on in the final overs.
The South Australian lured Deonarine out of his crease with a peach of an off-spinner first up, wicketkeeper Matthew Wade quickly completing the stumping to end Australia's long wait for a breakthrough.
While that wicket was welcome, his dismissal of Chanderpaul for 94 in his next over was the big scalp with the left-hander trapped LBW by another good ball to deny the 37-year-old a second hundred of the series.
Windies skipper Darren Sammy (1), Shane Shillingford (4) and Kemar Roach (0) all followed in quick succession as Lyon turned the match on its head.
Prior to Lyon's flurry of wickets the only Australian to enjoy success with the ball had been part-timer Michael Hussey, who ended a 62-run fourth wicket stand when he trapped Darren Bravo (38) LBW.
Chanderpaul was lucky to get past eight when an outside edge off Lyon early in the day clipped Wade's knee and Michael Clarke at first slip couldn't adjust quickly enough to snare the catch.
While Lyon had a day to remember it wasn't such a memorable one for James Pattinson (1-40), the young fast bowler going wicketless in the day and conceding 16 runs off his first over after the lunch break.
Pattinson left the field in the final session clutching his back and didn't return.
The day began in farcical fashion as players were called off the field by match referee Jeff Crowe before a ball could be bowled.
A power failure meant the television cameras were down and Crowe informed the umpires to take the players off the field over concerns playing without television footage would violate the West Indies Cricket Board's commercial obligations.
