Daniel Arms turned cricketing dream into reality at No.1 Sportsground on Sunday.
"It was something I'd always hoped I could do, hitting a six to win a final," Arms said.
"The image of the ball going over the boys' heads and them cheering, I won't forget that moment for a while."
The Magpies opening batsman, who finished 63 not out from just 30 balls against the Pumas (Hamilton-Wickham) in the decider, fired the parting shot and helped Charlestown claim the club's first T20 Summer Bash crown.
After embracing his teammates he was joined in celebrations by a group of friends, partner Brittney and his parents, including former Australian Country representative, Newcastle senior selector and Charlestown's T20 coach Greg Arms.
"It was good having everyone around," the 24-year-old, player of the T20 final said.
"I remember running around here watching him [dad] play, it was one of my favourite places No.1.
"He was certainly proud of me and the boys."
Following the breakthrough title, Arms is "keen to keep the ball rolling" for the rest of the 2018-19 season as the race towards two-day finals and a first grade premiership heats up.
Charlestown are third on the Newcastle District Cricket Association first grade ladder with two regular rounds remaining and at least six teams can still make the play-offs.
"It's unreal how close the competition is," Arms said.
"If us and Wests [fourth] lose we could be outside the top four, so we certainly know we've got a job to do to make that four.
"All of those clubs basically have must-win games from now on."
Adding extra motivation for Arms and most of the Charlestown squad, made up mostly of club juniors and players under the age of 30, is the chance to rectify last year's narrow semi-final loss.
"I remember sitting in the shed last year after losing by only a few runs and it was tough to take," he said.
"So there's a bit of hunger there to make sure we can go that step further this time."
The left-hander spent the off-season in England, playing for Eastbourne in the Sussex Cricket League.
It was his second UK stint, following a crack with Elland in the Huddersfield Cricket League in 2014.
This time around Arms ended up with 664 runs at an average of 31.62. His aggregate at Eastbourne was only behind former Kent first-class player James Hockley (1111 runs @ 55.55), who notched up five tons with a high score of 240.
Following on back in Australia this summer, Arms has 543 runs at 33.94 across all three formats featuring three fifties in the last fortnight.
