Test veteran Mitch Starc has defended Australia's new-look top order, which again misfired to keep the West Indies series opener on a knife's edge in Bridgetown.
Teenage opener Sam Konstas fell in single figures for the second time in a tough return Test and Cameron Green (15) continued to struggle at No.3 as Australia went to stumps on day two at 4-92.
The tourists lead by 82 runs after the visiting pacemen restricted West Indies to a first-innings total of 190 in reply to 180.
