WA and bad light deny South Australia in Perth

South Australia's push for their first Sheffield Shield win of the summer has been thwarted by Western Australia, with the hosts holding on for a draw at the WACA.

Set 303 to win in the fourth innings on Friday, the hosts were 6-195 when the match was called with five overs to play and South Australia forced to bowl spin in fading light.

The result left both teams at the bottom of the Shield ladder with no wins after three rounds, after each had defeats in their first two games.

After days of lost time through rain and bad light in Perth, Friday was not entirely fruitless, with Cameron Green getting a long stint in the middle ahead of the Ashes.

Set to bat No.3 for Australia in the first Test in Perth in three weeks, Green was out for 41 after facing 108 balls against South Australia.

Playing as a batter only on return from side soreness, Green's 41 marked his highest score of the summer for Western Australia ahead of a likely role at No.3 in the Ashes.

He wore a short ball to the left arm early, and also gave his side a full work out when he swung hard at a Nathan McAndrew ball.

But there were also several well-timed punches through the offside off both the back and front foot, that no doubt will have filled him with some confidence for the summer.

The allrounder was eventually caught behind pushing at a ball outside off stump to Liam Scott, although he appeared to disagree with the decision.

Green is bowling at full intensity in the nets, and is expected to be allowed to charge in for Western Australia in their next Shield round starting on November 11.

Officials will no doubt monitor that closely, as they weigh up whether to also keep Beau Webster in Australia's side for the first Test as another pace-bowling allrounder.

Meanwhile Cameron Bancroft also hit 58 at the top for WA on Friday, to go with his first-innings 122.

The hosts did briefly show an interest in trying to chase down the target in the final session on Friday, with Cooper Connolly launching two sixes off Ben Manenti.

Aaron Hardie also hit the spinner for a six, but after he was well caught by Jake Lehmann and Joel Curtis quickly followed, Western Australia shut up shop.
