The Bosch name sounds familiar because Anthony's father, Pedro—an actual doctor—is the man who prescribed Manny Ramirez the female fertility drug human chorionic gonadotropin in 2009. Anthony—who is not a doctor, despite his claims—is now being investigated by both federal and state law enforcement to determine his role in (possibly illegally) distributing HGH and testosterone.
His most famous client, Alex Rodriguez, has already had issues with performance-enhancing drugs so his connection—Bosch served as an advisor on "nutrition, supplements and blood analysis"—isn't unexpected. And it could be that Brian Cashman knew more than he let on when he mentioned Rodriguez could miss the whole year on a radio spot earlier this week.
Bosch has also been linked to other MLB players—more than 20, according to The Daily News—including Melky Cabrera. MLB is also involved and has handed over its information on Bosch to the authorities. According to Outside The Lines, MLB's issue is the geography.
MLB also is known to have a heightened angst about players' potential easy access to banned substances from the South Florida clinics, particularly because many of the most recent busts have a local connection — among them, Ramirez, Cabrera, Yasmani Grandal, and Bartolo Colon.
The interest is such that a source told "Outside the Lines" that MLB earlier interviewed a former University of Miami player about the availability of drugs in the area after he was busted with HGH in 2010.
It's a good bet that this won't be the last we hear of this investigation as the Protectors of The Game continue to retroactively carry out their self-appointed duties. It's the same reason why just one day after the BBWAA refused to allow anyone even tangentially associated with performance-enhancing drugs into the Hall of Fame, MLB announced it has extended it's HGH testing program to include the regular season.
