NSW have set South Australia a victory target of 326 as the Redbacks chase a breakthrough Sheffield Shield victory in the final round of the season.
NSW declared their innings at 8-305 midway through the morning session on day four at Karen Rolton Oval in Adelaide, leaving the home side 82 overs to claim victory.
South Australia were 1-44 off 14 overs at lunch.
Bailey Capel (8) was the only wicket to fall, caught at second slip off Trent Copeland.
NSW resumed at 4-235 and thumped 73 off 12 overs in a whirlwind hour at the crease.
Lachlan Hearne completed his highest first-class score before being bowled for 65 by Nathan McSweeney (4-89).
The left-arm spinner knocked over Chris Tremain with his next ball to complete the over but was unable to have a shot at the hat-trick ball as the Blues closed their innings.
Allrounder Jack Edwards was the other main contributor for the Blues with 38 off 44 balls.
Winless after seven matches, South Australia are assured of the wooden spoon while NSW's final hopes were ended yesterday as Western Australia and Victoria locked up their spots for next week's decider.
