South Australia hold a slim advantage at the midway point of their must-win Sheffield Shield clash against WA at Adelaide Oval, despite some extraordinarily obdurate batting from former Test opener Cameron Bancroft.
South Australia were dismissed for 389 during the morning session on Saturday, before the visitors scored at just under two runs an over to end the day at 4-165 off 83 overs.
Test opener Bancroft led the go-slow by using up 155 balls in a 3-1/2-hour knock worth just of 25, while WA managing just 50 runs during the entire middle session.
Bancroft seemed almost intent on blocking ever delivery, only to be undone when he allowed a Chadd Sayers delivery to crash into the stumps without playing a shot.
Bancroft scored seven off 63 balls during the morning session and, in concert with Jake Carder (21), WA's openers put on 32 off 28.2 overs for the first wicket.
Shaun Marsh was the main run-getter for WA with 63 from 111 balls, while Cameron Green (25no) and Josh Philippe (20no) resume on Sunday.
WA managed just four boundaries in their first three hours of their response as the home side racked up a remarkable 30 maidens.
Sayers (2-37) and Wes Agar (2-36) returned the best figures for the Redbacks bowling attack, with the former picking up his 300th first class wicket.
In contrast to WA's top-order, South Australia's unfancied tailenders scored quickly during the opening session with Sayers and Daniel Worrall adding 74 for the ninth wicket.
Sayers struck 58no, the highest score of his 75-match first class career, while No.10 Worrall was not far off his personal best with a handy 36.
A win for second-placed WA would all but end the Redbacks hopes after they managed just one victory from six outings before the mid-season break.
