South Australia 230 and 4 for 357 (Ferguson 107, Cosgrove 103, Cutting 2-57) lead Queensland 390 (Hemphrey 118, Benton 4-95) by 197 runs

Centuries from Mark Cosgrove and Callum Ferguson led a strong batting performance from South Australia, who edged in front of Queensland despite conceding a first-innings lead.

Queensland, who began the day at 8 for 354, added a further 36 runs before the final two wickets of Ben Cutting and Cameron Boyce were quickly picked up inside 11 overs of the day. However, their exploits on the second day meant that Queensland still had a healthy 160-run lead in hand.

South Australia looked to be heading towards more trouble when their opener Kelvin Smith was dismissed early in the second dig, but Cosgrove and Ferguson joined hands for a second-wicket association which yielded 156 runs. Cosgrove was eventually dismissed for 103 after striking 13 fours, but Ferguson carried on, adding a further 99 runs with Tom Cooper.

Ferguson's 13th first-class ton, a 196-ball 107, featured eight fours, and through he couldn't see out the day, fifties from Cooper (54) and Travis Head (53*) meant South Australia led by 197 runs when stumps were drawn, with six wickets still in hand going into the final day.
