Western Australia 1 for 149 (Wells 78, Bancroft 58) trail Tasmania 198 (Bailey 75, Green 5-24, Mackin 4-57) by 49 runs
Western Australia dominated Tasmania on day one of the Sheffield Shield match at Bellerive Oval in Hobart.
Winning the toss to have first use of a fresh pitch with the experimental Dukes ball, the Warriors bundled the Tigers out for 198 before making major inroads towards the hosts' first-innings tally.
Simon Mackin, so dominant in WA's win over South Australia at Glenelg Oval in the previous round, plucked another four wickets to lead the visitors' attack, while the 17-year-old debutant Cameron Green improved from a first up no-ball by claiming five wickets as he started the ball around disconcertingly.
Tasmania were awfully placed at 9 for 128 before the last pair of Sam Rainbird and Cameron Stevenson offered some resistance with a swift stand of 70. George Bailey top-scored with 75.
In reply, Western Australia gained the ideal start through Jonathan Wells and Cameron Bancroft. They added 130 before Wells was out to the allrounder James Faulkner for 78, leaving the Sydney Test debutant Hilton Cartwright to accompany Bancroft - not out at 58 - to the close.
