Baston's lawyer, David Rowe, told the jury in his closing address one of Baston's alleged Australian victims, known in court as KL, was the "business genius" behind a Gold Coast escort agency known as Bachelors Club.
Baston had a junior role and "was basically the security guard to make sure that the girls did not get assaulted", Rowe said.
Prosecutors, however, told the jury Baston was a "a master manipulator" who lured women into prostitution, beat them and kept hundreds of thousands of dollars they earned for himself.
The jury of seven women, five men began deliberations late last week and will return on Wednesday (NZT).
Baston was arrested in New York in December after KL flew from the US to Australia to renew her visa and her relatives alerted the US State Department.
