After being accepted into the University of NSW to study Environmental Management, Leeson made the move to Sydney and has been training with the NSW Breakers squad ahead of the WBBL season.
Leeson played just one game for the Sixers last season, but made a mark in the two overs she bowled, taking two wickets for just 11 runs.
“Carly is another of our exciting young players who brings a different skill set to our squad,” said Head Coach Ben Sawyer.
“Her medium pace bowling can be very challenging at times and she was rewarded for her hard work last season with her debut WBBL match, taking a wicket with her very first delivery.
“I know that this experience has driven her to work even harder on her game and I am certain that we will all see the benefits of that work this season.”
Leeson herself was also delighted to be back with the Sixers.
“(I’m) definitely very happy to be back,” she said.
“It’s a great feeling knowing you contributed to the team last year and then get signed again, so definitely looking forward to another great season with the Sixers.”
When discussing her goals for the season ahead, Leeson said she’d “continue to push to get into the starting XI. I probably didn’t play that many games last year so I’m obviously looking to become a regular starter in the team and make a regular contribution.”
The addition of key players to the roster, as well as the experience of the team, were key to what Leeson believes can ensure another successful WBBL campaign.
“With Lauren Cheatle coming into the side I think she’ll play a big role for us, as well as some of the younger players that are starting to build on their experience, like Lauren Smith,” said Leeson.
The Sixers start their campaign on Saturday 9 December at North Sydney Oval against the Melbourne Stars before backing up on Sunday 10 December against the Sydney Thunder.
