The Rayner's Dominic and Chris carried on with a 73-run partnership for the third wicket, with the skipper making 66.
Chris Rayner was undefeated at the finish with 56 after being joined by Justin Lock (19 not out).
However, with a smaller line-up there was still a few tense moments for the home side as there was not a lot of batting to come after the sixth wicket.
The winning runs came in the 43rd over.
Lance with 2-49 off 13 overs with his spinners was the pick of the bowlers, while Walker (1-41-8), Whiteman (1-15-5), and Robbie Power (1-34-8.4) all collected a scalp each.
Back at Victoria Park, Marist defeated St Johns Tech in a non-points game, which was played as a Twenty20 with an early 9.30am start, with most players getting a bowl.
