Six overs, 11 runs and two wickets were all that was needed on Sunday for Westbury to clinch a perfect season by adding the Cricket North crown to their Greater Northern Cup title.
Resuming at 8-384 with a 250-run advantage on the final day, the Shamrocks were bowled out for 395 within an hour at which point South Launceston opted to give up their pursuit of a third straight flag.
Knights captain Tom Waller conceded it was an unrealistic target just to make the minor premiers bat again.
"We were ready to go out and bowl when they conceded defeat and it was all done and dusted," said Westbury captain Richard Howe.
"We thought they'd have a crack but being 250 in front it would have been a fair ask just to make us bat again.
"At first it was probably a bit of a shock, then it began to sink in that we'd won so I'm pretty happy."
Ben Jackson claimed the final wickets of Jonathon Chapman, who did not add to his overnight 57, and last-man-in Nick Spencer before the Knights threw in the towel.
"We would have been a bit flat without those last two wickets and we wanted to restore a bit of pride so it was nice to get them," Waller said.
"Being close to 300 in front it was going to be pretty hard to chase the top team after such a long season.
"They definitely outplayed us for two days. They used the conditions to their benefit, sent us in and took their chances.
"They were the better side for three days and most of the season so thoroughly deserved their win.
"We also made the semi-final of the Greater Northern Cup so there are a lot of positives for us to build on in the next couple of years."
Dane Anderson was named player of the match for his impressive 108 which left Howe happy to reflect on a dominant final and season at a club where he has spent half his life.
"Obviously the first day really set us up," he said.
"Bowling a good team out for 134 in a final is a great effort with the ball and then we knew we just had to bat for time and with three or four really good partnerships and Dane making a hundred, it was enough to get a really good score.
"I thought 300 would probably win a grand final and it's been a few years since we've done that so to make 400 was a great effort.
"Everyone stood up in the final and it's good to bring the cup back to Westbury. We've played in the last eight grand finals and now won four but had lost the last three.
"We've had a really good crew throughout the year. We had three or four playing with the Raiders which was great for their development and we support that but to get them back for the finals of both the one-day and two-day competitions was fantastic and showed that if we put in the hard work the rewards will come."
Howe, who grew up in Scamander and joined Westbury as a teenager, said the club had become a second family to many and experienced its share of hardship.
"Being skipper, this means a lot to me. With the deaths we've had at the club in the last couple of years, it means so much to everyone. We lost some really good people around the club. It's a fantastic self-less club. It's very family-orientated, everyone gets along so well.
"I came here when I was 15-16 and now I'm 30 ... and feeling it."
