South Australia will bat after winning the toss against Tasmania in the rain-affected Sheffield Shield match in Adelaide.

Wednesday’s opening day was washed out, hampering third-placed Tasmania (28 points) in their bid to make ground on Western Australia (30 points) and leaders Queensland (32 points).

The Tigers named Matt Johnston as their 12th man, a role filled by Mick Delaney for the last-placed Redbacks.

Thursday’s play has been extended by an hour amid forecasts of more possible showers.

SA: Michael Klinger (capt), Tom Cooper, Tim Davey, Theo Doropoulos, Peter George, Travis Head, Nathan Lyon, Joe Mennie, Gary Putland, James Smith, Tom Stray, Mick Delaney (12th man).

Tasmania: George Bailey (capt), Jackson Bird, Luke Butterworth, Mark Cosgrove, Ed Cowan, Alex Doolan, James Faulkner, Brady Jones, Jason Krejza, Ricky Ponting, Jeremy Smith, Matt Johnston (12th man).
