Investigators believe the prescription for human chorionic gonadotropin, known as hCG and commonly used as a fertility drug, was written by Pedro Publio Bosch, a 71-year-old physician who has practiced family medicine in Florida since 1976, ESPN.com wrote. His son, 45-year-old Anthony Bosch, is believed to have worked as a middleman between Ramirez and his father.
Major League Baseball President Bob DuPuy confirmed the DEA's actions to ESPN.com on Thursday afternoon, saying, "We're aware of the investigation and our department of investigations is cooperating with the DEA." MLB said it will address the federal inquiry later on Thursday.
ESPN.com said it is unclear how far along the DEA is in its probe, but investigators want to know whether Pedro or Anthony Bosch ever supplied improper or illegal prescriptions to other people.
A '61 graduate of the University of Havana in Cuba, Pedro Bosch -- who, according to ESPN.com, has never faced disciplinary action in Florida -- practices in a medical building located across the street from Coral Gables Hospital in southwest Miami. Anthony Bosch is well known in Latin American baseball circles, and his relationship with players date back to the earlier part of the decade, according to ESPN.com.
Ramirez began serving his suspension on May 7 and is eligible to return on July 3. In preparation for that date, he's played two games for Triple-A Albuquerque. At the time of his suspension, the 37-year-old outfielder issued a statement explaining why he went to a personal doctor.
"Recently I saw a physician for a personal health issue," Ramirez said in the statement. "He gave me a medication, not a steroid, which he thought was OK to give me. Unfortunately, the medication was banned under our Drug Policy. Under the policy that mistake is now my responsibility."
HCG is not an anabolic steroid, but it boosts the body's testosterone levels and is commonly used by those coming off a steroid cycle.
