Brayden Ambler and Blake Harper made light work of South Wagga's run chase.
The premiers added to their strong start with an eight-wicket win over St Michaels at Geoff Lawson Oval on Saturday.
Nathan Corby helped Saints overcome a slow start as he top scored with 75.
However the Blues were able to restrict any resurgence as St Michaels finished their 50 overs at 9-188.
In response, Ambler (91) and Harper (72 not out) dictated terms to get the Blues home.
Captain Luke Gerhard was thrilled with how the team delivered.
"Blake batted very well and it was disappointing Braydo couldn't go all the way but we were definitely happy with how we performed as a team," Gerhard said. "It was definitely a good win and it was a long time coming to get back on the field.
"Everyone bowled very well and while we dropped a couple chances in the field other than that it was a perfect performance."
