The second Test between West Indies and Australia is heading for a draw as rain ruined much of the fourth day's play.
Only 30.4 overs were bowled on Wednesday with the Australians establishing a lead of 127 before rain forced play to be abandoned for the day.
The Windies began day three on 252-9 and added just five more runs before Carlton Baugh fell for 21 to end the innings, giving the Baggy Greens a first-innings lead of 54.
But they were soon in trouble themselves second time around as Kemar Roach took the first three wickets with only 57 runs on the board.
David Warner was first to go for 17 before Shane Watson lost his off stump without troubling the scorers.
Ed Cowan (20) battled hard for 78 deliveries before he became Roach's third victim and it was left to former skipper Ricky Ponting, who ended the day unbeaten on 32, and captain Michael Clarke, who will resume with three to his name, to see the tourists through to stumps.
Roach has taken eight wickets in the match to date, which represents his best return in the five-day game, and he will be looking for double figures on Thursday.
With only one day to go it looks as though the Test will meander along to a draw with only quick runs and a positive declaration giving Australia any chance of forcing victory late in the day.
A draw in Trinidad will mean Clarke's men will go into the third and final Test in Roseau with a 1-0 lead courtesy of their victory in Barbados last time out.
