New South Wales 256 (Hughes 93, Patterson 89, Winter 5-48) v South Australia
Winter, who took 5 for 85 on debut against Victoria last week, ripped the heart out of an experienced Blues middle order, with the home side threatening to build a huge platform.
Daniel Hughes and Kurtis Patterson put together a 117-run stand to move the total to 2 for 183 after the Blues had won the toss. But Hughes fell seven short of a century to the part-time spin of Tom Cooper.
Winter removed Moises Henriques shortly after, and the Blues lost their last eight wickets for just 73 runs to give the Redbacks the upper hand.
