ScorecardSouth Australia’s first Sheffield Shield victory over New South Wales since 2006, inside three days at Adelaide Oval, lifted the Redbacks to second on the competition table with two rounds remaining.The hosts quickly rounded up the remaining three wickets of the Blues’ second innings, Joe Mennie grabbing four to complete another prolific match. His partnership with the swing bowler Chadd Sayers has so far reaped 67 Shield wickets this season.SA’s pursuit of only 91 to win began nervously, but was steadied long enough by the opener Sam Raphael and the debutant Alex Carey to ensure that Doug Bollinger’s four wickets would not be terminal to the chase.The victory was a triumph for SA in the absence of their best batsmen Callum Ferguson and Phillip Hughes, but they must now enter their final two rounds without Sayers due to a side strain that is likely to sideline him for a month.
