A confident century from Cameron Bancroft has lifted Sheffield Shield leaders Western Australia to a seemingly unassailable position against Tasmania in Hobart.
Bancroft remains unbeaten on 148 in a knock that has taken the opener to top spot on the list of run-scorers in this season's Shield.
WA went to tea on day three with a mammoth lead of 442, after advancing to 3-311.
Bancroft has struck 17 boundaries to date in a 255-ball knock.
Strong support came in the form of Teague Wyllie with the pair adding 147 for the second wicket.
The teenage No.3 was denied a century when he edged a wide Beau Webster delivery to be caught behind for 80.
Bancroft and Wyllie batted throughout the morning session as Tasmania's bowlers struggled to make an impact on the Bellerive Oval wicket.
Aaron Hardie is the other batter at the crease on 26no.
