Western Australia will likely need some significant help from Tasmania to make the Sheffield Shield final after wickets tumbled for the home side on the penultimate day of their clash.
At tea on Monday, Tasmania were 0-11 after routing the hosts for 219 at the WACA.
Jordan Silk (9) and Tim Ward (1) were the not out batsmen as the Tigers moved to an overall lead of 306 runs.
Requiring a win to make the Shield decider, WA have been up against it since the second session on day one - losing key paceman Joel Paris to injury and then struggling to rope in the Tigers' batsmen in their 514-run first innings.
Resuming at 0-46 on Monday, things only got worse for WA.
The hosts lost Sam Whiteman (42), Shaun Marsh (14) and Cameron Bancroft (57) in the space of 35 runs as they struggled to score at more than three an over.
Shield-leading runscorer Cameron Green then looked to up the ante but departed for 17, caught by his Australian captain Tim Paine off the bowling of Lawrence Neil-Smith (2-28).
And when Mitch Marsh (24) was out on the cusp of lunch, lbw to Jarrod Freeman (4-72), WA were seemingly struggling to save the game, let alone win it at 5-162.
The middle session offered no respite as the last five wickets fell for 57 runs.
Backing up from his first-innings century, Beau Webster snared 2-32 for the Tigers while Jackson Bird had 2-50.
The only hope for WA now appears to be a generous declaration by the visitors, leaving them with a target to chase on Tuesday.
