In more positive news for magenta fans, left-arm quick Lauren Cheatle made a successful return from injury after 661 days since her last match for the Sixers due to a shoulder reconstruction and bicep injury.
"I’m a bit conflicted at the moment. Obviously would loved to get away with a win, but really happy to back playing cricket," Cheatle said.
"It was really good, it felt good.
"There's a bit of management coming back. I'd love to play every game throughout, but that's not my call."
The Sixers were well in the contest with the Heat 2-29 in the sixth over. Quick thinking by Alyssa Healy behind the stumps stumped Grace Harris (10) after the Australian wicketkeeper caught the opener napping and out of her ground.
However, a solid captain’s knock by Jess Jonassen (34) and quick fire 23 from 10 by Laura Kimmince were pivotal for the Heat.
