Heat's WBBL entertainer keeps show going

Brisbane Heat's Laura Kimmince has the highest strike-rate in the history of the WBBL, and she wants to take her entertainment-first approach into the finals.

Laura Kimmince's simple approach to batting has made her the fastest scorer in WBBL history and she's not about to put the brakes on come finals.

Kimmince shapes as the real x-factor in the Brisbane Heat's shot at a WBBL three-peat, which goes on the line in Thursday night's semi-final against Sydney Thunder.

The 30-year-old has produced the fastest scoring season in the competition's history, going at a strike-rate of above 200 while still averaging 20.

It's also taken her to the top of the tree in terms of career strike-rates in WBBL, just pipping Hobart's Chloe Tyron and Sydney Sixers star Alyssa Healy.

"I say it all the time: People don't want to come and watch me hit a single down to long-on six balls in a row," Kimmince told AAP.

"I just go out there to try and make the game as entertaining as possible.

"At the end of the day we're just another form of entertainment, and if it's working I'll keep going."

Kimmince's sister Grace Harris has often earned the plaudits for her swashbuckling style, but this summer Laura has arguably outgunned her.

Her highlights this season have included a regular willingness to reverse sweep, including a massive six over point against Scorcher Sophie Glenn.

And after hitting 125 from just 52 balls in her last five innings, it's an approach she has vowed to stick with in the finals.

"It's just trying not to over-think," Kimmince said.

"I've liked varying it up with the reverse shot. I have worked on that a lot more to make it a proper shot, not just a hit and hope.

"And trusting if I do it hit it near a person it's over their head."

Kimmince's cricket is symbolic of the way the Heat have played.

Written off at the start of the season following the exits of Beth Mooney and Sammy-Jo Johnson, they fell to 1-4 before throwing caution to the wind and winning seven straight.

"It was just about not doubting your skills," Kimmince said.

"Everyone wrote us off early. We probably got a bit of playing that way - just trying to stay in rather than playing how we play."
