Former Zimbabwean Test batsman Murray Goodwin has been recalled to boost the West Australian top order for its vital Pura Cup match against South Australia starting Wednesday.

The 29-year-old takes the place of youngster Scott Meuleman while left-arm spinner Brad Oldroyd is expected to carry the drinks instead of Kade Harvey against the new-look Redbacks.

The Warriors and Redbacks are just two of the four teams still in the mix for final berths heading into the final round of matches.

And while Queensland is still in the driving spot to make the final on 30 points, it needs two points against Victoria this week to ensure its third home final in a row.

Meanwhile Western Australia and Tasmania are locked on 24 points and need large outright victories to give themselves their best shot at making the final.

The Redbacks (20) though have an outside chance of playing next week but need an outright victory over the Warriors and for results to fall their way.

"There's a few combinations, I think everyone will be pulling out their calculators on Saturday to work out the quotients," said Warriors coach Mike Veletta.

Veletta hoped that the Redbacks' desire for a result would help the Warriors gain the valuable six points.

"They will have to be aggressive, there is no point finishing mid-table when you can make the final," Veletta said.

"And with Greg Blewett as captain, he's a pretty aggressive player."

The South Australian selectors have made four changes to the Redbacks team which has been on the slide since Darren Lehmann's recall to the national team this summer.

The team has lost its last two four-day matches at home in the left-hander's absence.

Selectors have brought in batsmen Shane Deitz and Daniel Harris, all-rounder Ryan Harris and fast bowler Paul Wilson for the match.

But it will be the Warriors who will have the chance to bring back Test opener Justin Langer into their line-up if they make the final.

Langer's national duties on the South African tour finish next Tuesday giving him ample time to return to Australia for the match.

The Warriors also enter Wednesday's clash full of confidence coming off their remarkable come-from-behind victory against Victoria in Melbourne this month.

"We have got some momentum going our way, we did not play well against Victoria, but we fought back and showed some character," Veletta said.
