Cameron Bancroft has produced a breakthrough Sheffield Shield century but rain and a stubborn knock from Liam Scott ended Western Australia's bid to secure victory against South Australia.

Bancroft struck an unbeaten 105 off 255 balls as WA declared at 3-243 in their second innings, setting the Redbacks a victory target of 364 off 90 overs.
