This year's leading crew will face a group of experienced campaigners as Launceston host Westbury in next weekend's Greater Northern Cup grand final.
Set to be the first all-Northern final since Mowbray and Riverside did battle in 2015-16, the pair got through in very different fashion - Westbury by 10 wickets and Launceston by two.
At Windsor Park a disciplined bowling effort put Dan Murfet's Shamrocks in a commanding position early, dismissing the Blues for just 75 before chasing the target without losing a wicket.
"We know with our best bowling line-up if we consistently put the ball in difficult areas, that we can can build a lot of pressure on the batting side," he said.
"Luckily enough we were able to do that and the chances we created seemed to go to hand."
Heading into next week's final brimming with confidence, the skipper lauded the work of experienced workhorse Nick Spencer, who took 3-27 while bowling 10 overs straight.
"He usually does his best work when he bowls 10 straight rather than having to get himself warmed back up - the old muscles probably don't recover as quickly as they once used to," Murfet said.
"In saying that, his full 10-over spell was bowled at good pace and barely missed the mark, so I'm very pleased with him."
The Shamrocks' other bowlers all took wickets, setting the tone for Jesse Digney (48*) and Dom Barrett (24*) to finish off the game and send Westbury to their third consecutive Greater Northern Cup final.
Aidan O'Connor's unbeaten 16 topped the scoring for Riverside coming in at number eight, while Pete New's 14 attempted to keep the top order together.
Over at the NTCA Ground, Launceston held their nerve to continue their unbeaten streak as they aim for elusive silverware this season.
Untouchable in 13 matches this season, coach Alistair Taylor - a member of a crucial 80-run stand with James Curran - said the team is building a culture full of belief.
"It obviously wasn't ideal to lose 3-3 and have the tail-enders come in and do the job but I have complete faith in the boys," he said.
"I was pretty nervous but Rowan [Smith] is obviously pretty experienced and Cuz [James Curran] is batting really well, so those boys just had to see off Sam O'Mahony who obviously bowled really well and they saw him off and ran well between the wickets."

The Lions restricted visiting Orions to 7-188 despite the best efforts of the in-form Miles Barnard, who was dismissed for 98 by Dihan Cloete.
While Dilan Sandagirigoda claimed two wickets, the work of Ben Humphrey (1-6 off eight overs) didn't go unnoticed by Taylor.
Looking strong early with the bat, the home side quickly fell to 3-31 before Taylor and Sam Elliston-Buckley steadied the ship.
Elliston-Buckley departed for 24, bringing Curran to the crease for the pair's 80-run stand until Taylor was dismissed for 53, leaving the Lions at 5-152.
Two more quick wickets had hearts in mouths, as did Curran's (60) with two runs to spare, but Rowan and Daniel Smith saw the side home.
