The Wagga cricketer claimed her first WBBL title as the Thunder cruised to a seven-wicket win over Melbourne Stars at North Sydney Oval on Saturday night.

The 19-year-old led the way for the Thunder in the run chase, scoring 23 at the top of the order to put her team well on the way to victory.

The Thunder chased down Melbourne's tally of 86 with more than six overs to spare.

Trenaman said it is a moment she will never forget.

"It's absolutely unreal. It's something pretty special," Trenaman said.

"Players don't always get to play in a final. I guess, being a Thunder supporter from the first year, they won it then, and I came on as a rookie the next year, then contracted the year after, you just dream of playing in those big moments, playing in those finals.

"Obviously it was the Stars' first final in six seasons so I guess that just shows they don't come around very often. Not only to sneak a win (on Saturday night) but to actually dominate the game was an unreal feeling."

Already an accomplished cricketer at such a young age, Trenaman said the final win is up there as one of the highlights of her short career.

"It's right up there. It's pretty special," she said.

"One of my goals this season was to be a starter in the 11 for the Thunder and being given the opportunity and shown the faith by Trevor (Griffin) and our batting coaches to open was really encouraging.

"To take that opportunity and, I know it was a small total, but to contribute and get the team off to a decent start to ensure we did chase those runs down, with all the work that's gone in during the round games to get us into a decent position with momentum in the finals, it rates right up there.

"I played with a lot of the younger girls, whether its underage for NSW Country or Aussie under 19s honours, so being by their side, it's really special that's for sure."

Trenaman was second top scorer in the final for the Thunder, with her 23 runs coming off 26 deliveries, and it included four boundaries.

She was happy to play a part in the win.

"It would have been a stinker if I got out cheaply early on," she laughed.

"To put on 20 odd runs and get the team closer to that total, have a few good partnerships, yeah it's really special. I guess I'm a bit filthy with the way I got out. I would have liked to have been there at the end but I think the culmination of everything that happened in the season and just go out there, bat, have a smile on your face and really enjoy the moment was special."

Trenaman now gets a couple of weeks off before having to return to training and prepare for the 50-over format.
