The Statewide Super SA Scorpions opener forged an 88-run stand with Eliza Doddridge (33), with Patterson’s innings including 10 fours and a six.
The Scorpions reached 8/202 in a reduced 40-over match due to wet weather, with Ellie Falconer the next highest run-scorer, coming in at nine and compiling a handy 21.
Tahlia McGrath (1/30) dismissed Sasha Moloney (two) in McGrath's first pre-season game for the Scorpions after returning from the Kia Super League earlier this week.
The Tigers lost both openers cheaply, however Emma Flint (67) and Meg Phillips’ (38) 102-run partnership had Tasmania back on top.
After a win for SA on Thursday, Friday’s rain-disrupted match saw Tasmania reach 6/205 with just three balls to spare.
Stacey Oates and Sam Betts both took one wicket, while Emerging Scorpions Brooke Harris and Sophie Roberts also collected a single scalp each.
The Scorpions open their WNCL campaign on 22 September at Karen Rolton Oval.
