It was Patterson’s turn to shine, after Tahlia McGrath set the batting tone the day prior, making her own ton against Victoria.
“I feel like I’ve had a pretty good pre-season, I just haven’t been able to move on from the 40s really,” Patterson said.
“I just knuckled down today and felt good - I feel like it’s been a long time coming so it’s amazing to finally do it.”
Scorpions captain Megan Schutt lost the toss for the second consecutive day, seeing WA send SA in to bat first.
Patterson and Tabatha Saville (17 off 45 balls) managed a 48-run opening partnership, with the former able to continue building the innings with McGrath (22 off 33 balls).
A small middle-order collapse saw the Scorpions lose 3/10, but late cameos from Samantha Betts (21 off 29 balls), Schutt (20 off 10 balls) and Sarah Lowe (22 off 19 balls) rescued the innings, with SA piling on 50 runs in the last five overs.
WA were chasing 254, giving the Scorpions bowlers an opportunity to redeem themselves after taking just three wickets against Victoria the day before.
It was Schutt (3/39) who nabbed the first two scalps, including the dangerous Nicole Bolton for just six runs.
Amanda-Jade Wellington (3/43) removed Sophie Devine (26 off 22) before she was able to go big and Samantha Betts dismissed WA top-scorer Heather Graham (70) in the 44th over to have WA in trouble at 8/192.
The WA tail managed only an additional 13 runs after Graham’s exit.
“We bowled a lot better than we did yesterday…(Megan) trusted her bowlers today and was able to set the field however she wanted it,” Patterson said.
“It’s a lot easier (having one win) than going two down. It just seems like it’s going to be a strong competition this year and anyone could take it out.”
