Mark McGwire, Sammy Sosa and Tony Gwynn worked with the FBI to help catch forgers who were selling faked items in the sports memorabilia market, according to a broadcast report.
The athletes helped the FBI spot fake signatures during a two-year undercover FBI investigation known as "Operation Bullpen," ABC's "20/20" reported.
Gwynn told "20/20" he went to the FBI three years ago after discovering the San Diego Padres' gift shop was victimized by suppliers of fake baseball memorabilia.
