MIAMI — A federal investigation into a South Florida anti-aging clinic may soon uncover the names of more athletes who purchased performance-enhancing drugs.Former Biogenesis of America owner Anthony Bosch and six others agreed to plead guilty Tuesday in what prosecutors called a wide-ranging conspiracy to distribute the drugs to major-league baseball players and high school athletes.The investigation uncovered previously unnamed baseball players who purchased drugs from the clinic, though none of those names was immediately revealed, espn.com reported."There probably are going to be a bunch of guys who are worried now that the feds are involved,'' Kirk Radomski, the former Mets clubhouse attendant who provided PEDs to players, told USA Today . "I think baseball proved last year that it doesn't take much for baseball to suspend these guys. If Bosch comes up with more names, a lot of the guys won't fight it."The charges filed Tuesday marked one of the biggest salvos in a case that has dragged on for nearly two years. The case has sparked lawsuits, mudslinging and suspensions against numerous major-leaguers, including Yankees star Alex Rodriguez. Also charged was Yuri Sucart, 52, a cousin of Rodriguez who the third baseman has said provided him with steroids from 2000 to 2003 when Rodriguez played for the Rangers. Sucart and the others are accused of acting as recruiters, setting up meetings between the athletes and Bosch, who introduced himself as "Dr. T," authorities said. Professional athletes paid up to $12,000 a month for drugs provided by Biogenesis, while high schoolers paid up to $600 a month. All the clients were promised that the substances would not be found through testing, prosecutors said. "He is not a doctor," Mark R. Trouville, chief of the Miami Drug Enforcement Administration office, said of Bosch. "He is a drug dealer." U.S. Attorney Wifredo A. Ferrer said Bosch did not have a medical license."As with many drug cases, these defendants were motivated by one thing: by money," he said.Major League Baseball was not part of the criminal investigation and declined comment. No athletes were charged nor named in court documents. Authorities said Bosch admitted to providing performance-enhancing drugs to 18 high schoolers. As part of his cooperation, Bosch agreed to provide testimony as well as documents and records in the case. For now, he has pleaded not guilty and his bail was set at $100,000. He faces up to 10 years in prison."In terms of an agreement to cooperate and plead guilty, Bosch has agreed to do that," Ferrer said.Late last year, Bosch was Major League Baseball's star witness as the commissioner's office sought to punish Rodriguez with the longest suspension ever for doping. During a contentious hearing in New York, Bosch offered testimony that led to Rodriguez's being barred for the season.
