Fast bowler Kemar Roach claimed 2-10 as West Indies rebounded from conceding a first-innings lead of 54 to reduce Australia to 40-2 in their second innings by lunch on day four of the second Test on Wednesday.
The home team, overnight 252-9, quickly folded for 257 all out after four deliveries. Australia totaled 311 in its first innings. Carlton Baugh was trapped leg-before wicket for 21 by left-arm spinner Michael Beer, who claimed 2-56. Fellow spinner, offspinner Nathan Lyon, took 5-68.
But Roach hit back strongly with the wickets of opener David Warner (17) and Shane Watson (0) in his first over at Queen's Park Oval.
It could have been even better for the Caribbean side but Ed Cowan survived a chance to first slip Darren Sammy off Edwards before he had scored.
Cowan was undefeated on 14 when persistent rain sent the players off 45 minutes before the scheduled lunch break.
