South Australia, despite a superb century from Daniel Drew, slipped to a 22-run defeat to reigning champions Western Australia in their one-day clash.
Nick Hobson closed the innings in style with a 24-ball half-century as WA slammed 122 in their last 10 overs.

Drew featured in handy partnerships of 96 runs with opener Henry Hunt (47 from 71 balls) and 95 with Nathan McSweeney (51 from 44).
But a middle-order slump of 5 for 98 cruelled SA's chances of victory, with D'Arcy Short taking 3 or 81 from eight overs
In WA's innings, Short fell for his second duck in three days, shouldering arms second ball, and Josh Philippe also departed early to leave their side 34 for 2 in the ninth over.
Cameron Bancroft (66) and Whiteman then seized the momentum with a 105-run partnership for the third wicket.
Bancroft, who was in prolific run-scoring mode last summer in all formats, struck eight fours in his 99-ball knock but chopped on to his stumps to give Nathan McAndrew his second wicket.
Turner then blazed a half-century from just 28 balls, including five sixes and three fours, to put on a rapid-fire 119-run stand with Whiteman in just 10 overs.
Whiteman was dropped on consecutive balls in the 70s while Turner finished with eight fours and six sixes.
