The Bloods looked well held facing Tatura's bowling attack in the early stages of Saturday's round three clash at Vibert Reserve, grinding their way to 4-94.
But from there Luke Forge (71 not out from 71 deliveries) and Nathan Jones (53 not out from 64) were able to tee off in an unbroken 118-run partnership to take their side's total to 4-212 from 45 overs.
Between them the pair slashed 15 boundaries - including one six - and took Karramomus from a handy position to a winning one at a quick pace.
The duo's work was then backed up by the likes of Chris Keady (2-7), Jason Ibbotson (2-22) and Lachie Keady (2-29) with the ball as Tatura was restricted to 8-155.
Tatura openers Raj Singh (26) and David Miller (46) looked to set a strong platform for the visitors, but only captain Michael Archer (25) was able to also make it past 10 runs.
Singh (1-10) and Sean McAllister (1-15) finished with the best bowling figures for Tatura, with Jayden Armstrong, Bailey Archer and Connor Davies also bowling tightly.
“I think we bowled really well,” Archer said.
“At the back end we probably let them get away from us a bit, but Jayden and Bailey were really good with the new ball.
“He (Davies) wasn't going to bowl all week and then he was feeling good, so he was just going to bowl a couple of overs and see how he went. But he ended up bowling eight because he was bowling really well.
“Raj was really promising again with the bat and Dave batted really well, but we needed one of us to get a big score once we were set if we were going to win.
“We probably just need to clean up the fielding a bit and bowl a few less boundary balls, if we do that on another day its 170 or 180 that we need and we're right in the game.”
No matter the result, both sides gathered after the clash to celebrate the memory of Rod Kilmartin - a much-loved and missed servant of each organisation.
“It's always a good day and always played in the right spirits,” Archer said.
“It was great to catch up with all of the boys afterwards.”
