Marsh takes over the captaincy following the retirement of Adam Voges, who remains with the orange army as Head Coach for BBL|08.
The 26-year-old said he can’t wait to lead the players as they prepare for their first full season at their new home - Optus Stadium.
“It’s a great honour to be able to lead any WA team,” he said.
“We’ve had great success with this side and to be given the opportunity to captain the Scorchers again is really exciting.
“It’s important we build on last year’s efforts, BBL|07 didn’t finish the way we would’ve liked after finishing on top of the ladder.
“I’m looking forward to working alongside Vogesy. If we continue to work hard and look after our mates I’m sure we will continue to have success as a team and an organisation.”
Lanning signed with the Scorchers WBBL side last summer but was unavailable due to shoulder issues.
Now the mega star, who’s represented Australia in all formats, is fully fit and itching to get back on the field with her new WBBL team.
“I’m really looking forward to the season, watching on from the sidelines last summer wasn’t fun at all,” she said.
“The girls have been so close in the last two campaigns, I know they’re all looking to go one better this time round and I can’t wait to hopefully get us there.”
“There is some young players in the squad as well as a good mix of experience, but the young players we have are all very talented.
“The likes of Piepa Cleary and Heather Graham have both been with the National Performance Squad, those girls have a great opportunity now to step up and take their game to the next level.
“I’m really excited to pull on the orange for the first time, playing in front of our great Members and fans and hopefully claiming some silverware.”
The Scorchers women get their WBBL|04 season underway in Melbourne on Saturday 1 December.
While the Men’s campaign also begins in Melbourne, on Thursday 20 December.
