Both Western Australia and Tasmania will head into this week's Sheffield Shield clash at the WACA requiring an outright win to keep their fading final hopes alive.
The pair currently occupy the bottom two places on the points table having both won two of their seven games to date, but victory for either side would lift them into third place and within touching distance of front runners Queensland and Victoria.
And the Warriors should be further motivated by the desire to avenge both the humiliating innings defeat they suffered when the two sides met in Hobart back in November and another disappointing loss to the same opponents in Wednesday's Ryobi Cup clash at the WACA.
In terms of team news for the hosts, skipper Adam Voges, Shaun Marsh, Nathan Coulter-Nile and Jason Behrendorff will all miss out, with Mitch Marsh, Burt Cockley, Ryan Duffield, Luke Towers and Tim Armstrong coming into the 12-man squad and highly-rated spinner Ashton Agar could also feature after returning from his training stint with the Australia Test squad in India.
Mitch Marsh is shaping as the Warriors' go-to man having marked his return from a hamstring injury by plundering a superb century in the Ryobi Cup defeat, while paceman Michael Hogan will look to add to his season tally of 17 Shield wickets as he spearheads what will be a relatively inexperienced bowling attack.
Tasmania, meanwhile, will again be without vice-captain Tim Paine who has Australia A commitments, but will otherwise be at full strength following the return from international duty of George Bailey, Ben Laughlin and James Faulkner.
And the visitors have some key men in fine form, notably Ricky Ponting - who was simply imperious in reaching 200 not out during his side's most recent Shield outing against New South Wales - and Luke Butterworth, who has already taken 30 wickets this season of which five came during the Tigers' rout of the Warriors at the Blundstone Arena.
The hosts will also have noted the promise of young batsman Jordan Silk who struck a run-a-ball 66 against them on Wednesday, the second time the 20-year-old has passed the half-century mark in as many one-day outings.
Justin Langer's men have blown very much hot and cold at the WACA this season, losing heavily to both Victoria and New South Wales before crushing South Australia by 110 runs, while the Tigers remain unbeaten on their travels with two draws and a win, although they were beaten by 25 runs in the corresponding fixture last year.
