Garcia, currently ranked 6th in the world, announced on Tuesday that Ferrero would be his caddy for the competition running from December 11th to 14th.
The Spanish golfer will be defending his title and hoping to once again claim the $1 million prize money.
His caddy last year was his girlfriend, Katharina Boehm, but she will look on as a spectator when Ferrero takes control of the bag.
"Katharina is fine. She is happy to step aside and support from the side lines. It always helps to have a friend on your bag. It is good fun to be able to enjoy golf and have a good time with a good close friend," Garcia told the Asian Tour website.
The 34-year-old Ferrero, nicknamed 'mosquito' because of his quickness and slight build, was ranked as the world's no.1 tennis player in 2003, shortly before a certain Roger Federer began his long reign at the top.
Ferrero won the 2003 French Open the same year and enjoyed a long professional career before retiring in 2012.
