Head and Carey marshal South Australia's chase
South Australia 2 for 257 (Head 80*, Carey 80*, Weatherald 53) beat Tasmania 7 for 255 (Jewell 104, Silk 87) by eight wickets
Travis Head and Alex Carey combined in an unbroken stand of 130 to earn South Australia a bonus-point eight-wicket win against Tasmania.
Head, South Australia's captain, and Carey both finished unbeaten on 80 as victory came with 11.2 overs to spare. Carey faced just 52 balls, hitting 13 fours and six, after making starts in the first two matches without converting.
Caleb Jewell had scored his maiden one-day hundred but Tasmania could not find a late push to their innings as they fell from 2 for 208 in the 43rd over to 7 for 255.
Jake Weatherald (53) and Callum Ferguson added 50 for the first wicket in less than seven overs to give the chase early momentum. Riley Meredith, who has impressed at the start of the season, broke through and later added Weatherald's wicket but he went for 8.62 from his eight overs.
Cam Valente's medium pace had set back Tasmania's innings when he removed the in-form Ben McDermott and captain Matthew Wade before Jewell and Jordan Silk (87) put on 162 in 31 overs for the third wicket.
However, both set batsmen fell in quick succession - Silk to Adam Zampa and Jewell to Kane Richardson - as the South Australia attack quelled the late scoring. Outside of the 17 boundaries hit between Jewell and Silk, Tasmania's batsmen only managed another five between them.
