The Australia legspinner, who captained the Stars during 2022/23 in the absence of Glenn Maxwell and has a contract for the next two seasons, is poised to be traded for Sam Harper
Australia's Adam Zampa has requested to be traded from Melbourne Stars to the Renegades ahead of the next Big Bash League season.
The 30-year-old's switch would prospectively see Sam Harper move across the city in the other direction.
Both clubs and players have exchanged non-binding correspondence on the deal which can be completed when the official trade window opens later in the year.
No agreement can be reached during Cricket Australia's contracting embargo period, which began following last weekend's final.
The news comes after Stars failed to qualify for the playoffs for the fourth time in six seasons, finishing bottom with only three wins from 14 matches.

Zampa, who joined Stars for the 2015/16 campaign and had committed for the next two seasons, captained in the absence of Glenn Maxwell but with little success.
In a statement, Stars general manager Blair Crouch said: "This trade would allow us to target several other quality players, and we look forward to making a number of announcements regarding new signings once the contracting window re-opens.
Renegades, meanwhile, enjoyed an encouraging season. After three successive eighth-place finishes, they captured third in the regular season to set up a meeting with Brisbane Heat in the qualifier, which they lost by seven wickets.
Harper, 26, played a single season for Stars in 2016/17 before joining Renegades two years later. In 68 matches for the team he's scored 1,433 runs at 23.11, hitting 10 half-centuries.
