Major League Baseball Players Association head Michael Weiner released a statement Thursday, concerned with media reports in the Biogenesis investigation.
ESPN, earlier this week, reported that Milwaukee's Ryan Braun failed to answer questions from Major League Baseball regarding his link to the Biogenesis clinic that allegedly provided players with performance-enhancing drugs.
The network has also indicated that New York Yankees slugger Alex Rodriguez would be interviewed later this week in regard to the same clinic, and other media outlets have indicated that the three-time MVP would likely refuse to answer questions about his alleged involvement.
"The leaking of confidential information to members of the media interferes with the thoroughness and credibility of the Biogenesis investigation," said Weiner in a statement. "These repeated leaks threaten to harm the integrity of the Joint Drug Agreement and call into question the required level of confidentiality needed to operate a successful prevention program.
"The Players want a clean game and they demand a testing program that is not only the toughest in professional sports, but one that guarantees each player due process rights accompanied by strict confidentiality provisions. As I stated last month, the Players Association remains in contact with the Commissioner's Office regarding the investigation, and they continue to assure us that no decisions regarding discipline will be made until the investigation is complete. It would be unfortunate if anyone prejudged the results of the investigation based on unsubstantiated leaks that are a clear violation of the JDA."
ESPN has reported that as many as 20 players could be suspended for alleged involvement with the Florida anti-aging clinic run by Anthony Bosch, who is said to be cooperating with Major League Baseball in its investigation.
The Biogenesis controversy began in January when the Miami New Times reported it had obtained medical records of players who had purchased banned substances -- namely human growth hormone -- from the clinic.
