Queensland 7 for 400 (Forrest 129, Hartley 89, Botha 4-103) lead South Australia 387 by 13 runs
Peter Forrest made the ideal start to putting behind him the difficulties of his previous Sheffield Shield season with a hundred to earn Queensland first-innings points against South Australia on a friendly batting surface at Glenelg.
Forrest and Chris Hartley, the captain who was laid low by a stomach bug on the opening day, added 194 for the second wicket after the innings had been in the balance at 4 for 183 when Nathan Reardon became Johan Botha's fourth wicket.
Forrest, who made just 395 runs at 19 in first-class cricket, struck 17 boundaries and three sixes during his eighth century before cutting legspinner Adam Zampa to slip. Hartley fell four overs later, but by then had taken Queensland into the lead.
There was plenty of toil for the Redbacks attack with Botha sending down 47 overs while the opening bowlers, Chadd Sayers and Joe Mennie, closed with 31 apiece.
