SA vs TAS: Day Three highlights

The display followed a sporting declaration from Tasmania just after Tea at 5/345 still trailing the hosts by 145 as the two teams vie for a result.

Tigers skipper Matthew Wade made 89 before part-time spinner Cooper had him caught at deep square-leg.

Wade and Alex Doolan's unbeaten 170 from 403 balls made up the bulk of Tasmania's total with Test captain Tim Paine (29*) also unbeaten.

Cooper was the surprise for South Australia with the ball, claiming three wickets in the second session of the day to finish with figures of 3/76. The visitors lost 3/56 in a 20-over span from Cooper’s hand.

Wes Agar continued his tidy form to, incredibly, concede just 19 runs from his 20 overs. He also took a wicket and bowled 12 maidens.

Joe Mennie was SA’s other wicket-taker with figures of 1/46 and six maidens in his return from injury.
