Ramsbottom has moved swiftly to sign a new professional following the signing of Daryn Smit by Derbyshire this week.
The club has announced the signing of another South African in Grant Thomson.
The 28 year-old Thomson is a right handed batsman and opening bowler who plays for the Northerns and Titans franchise.
Ramsbottom Cricket Chairman Andy Dalby said: "We look forward to welcoming Grant and his wife to Acre Bottom for the 2017 season.
"When I found out that Daryn was signing for Derbyshire I wanted to act quickly in securing a quality replacement.
"I believe this has been done as Grant comes highly recommended from a number of fellow professionals (including Daryn) and I want to place on record my thanks to Gary Hunt of Cric-Intro for his support on this signing."
