Tasmania 254 and 1 for 6 trail South Australia 346 (Weatherald 126, Carey 73, Bird 4-70) by 86 runs

Jake Weatherald's second century of the season against Tasmania, a commanding innings from Alex Carey and useful lower-order runs put South Australia in control as they hunt that elusive Sheffield Shield victory.

Weatherald, who scored a career-best 198 when the sides last met, and Carey added 128 for the fourth wicket after South Australia had lost 3 for 8 to slip to 3 for 57 in the morning session.

Carey, who struck 11 boundaries, looked set for a century before being well held at second slip when he drove at Riley Meredith.

When Weatherald's fine innings was ended, lbw to Jackson Bird, and Chadd Sayers followed to the same bowler, South Australia were 8 for 263 - a lead of just nine - before Nick Winter and Joe Mennie added 73 for the ninth wicket. Mennie was last-man out for 49.

With four overs to bowl, South Australia's day ended on a high when Winter trapped Alex Doolan lbw with the last ball of the day. However, although the opener wasn't playing a shot the decision looked dubious.
