New South Wales 256 and 1 for 61 (Hughes 32*, Cowan 16*, Winter 1-26) lead South Australia 281 (Cooper 105*, Andrews 50, Copeland 4-63) by 36 runs

An unbeaten century from South Australia veteran Tom Cooper helped the Redbacks claim first-innings lead over New South Wales in a tight tussle at the SCG.

The Redbacks were 7 for 141 at one stage and were looking at a significant first-innings deficit. Trent Copeland had taken four of the first seven scalps for the home side. But Cooper and Tom Andrews combined for a 96-run stand to dig the Redbacks out of the mire. Andrews made his maiden first-class half-century before falling to the legspin of Daniel Fallins.

Cooper looked set to be stranded but sneaked to his 10th first-class hundred when the Redbacks were nine down. Fallins finished with three wickets on his Sheffield Shield debut.

Redbacks paceman Nick Winter trapped Nick Larkin early in the Blues' second innings but Daniel Hughes and Ed Cowan saw them through to stumps without further loss. Cowan passed 10,000 first-class runs in the process.
