Anthony Bosch has been charged with one count of conspiracy to distribute testosterone, according to federal court records.
The documents state that Bosch willfully conspired to distribute the anabolic steroid testosterone from October 2008 through December 2012, but do not state whether the charges have anything to do with Rodriguez or any other MLB players.
Rodriguez bought human growth hormone and other substances from Bosch's Coral Gables clinic in Miami between 2009 and 2012, according to a Miami New Times report from January 2013 that sparked an MLB investigation.
The Yankees superstar was eventually suspended for all of the 2014 season and 13 other players were also disciplined by the league.
In addition to Bosch, nine others have also been arrested in the case, Drug Enforcement Administration spokeswoman Mia Ro said.
[Updated at 10:10 a.m.: Yuri Sucart, Rodriguez's cousin, was among those arrested Tuesday morning, Ro said. It was not clear what he was charged with. Rodriguez has said Sucart had obtained and injected him with steroids when A-Rod was with the Texas Rangers from 2000-03.
Lazaro Daniel Collazo, a former pitching coach for the universities of Miami, Louisville and South Florida who has also worked as a private instructor with high school, college and professional pitchers, was also charged.]
