CHICAGO -- Agent Scott Boras said on Friday that the leaking of names associated with Major League Baseball's investigation into Biogenesis, a closed Florida anti-aging clinic accused of distributing banned performance-enhancing drugs, does a disservice to the game and violates the collective bargaining agreement.
"I don't know where [the leaks] are coming from," Boras said at Wrigley Field, where his client and No. 2 overall draft pick Kris Bryant signed with the Chicago Cubs. "There are only a very small group of parties that have access to this information.
"What we have is a failure to follow a collective bargaining agreement. Whenever these things happen, whoever is doing it, is not serving the game well. The witnesses that we know have -- at best -- behavior in their life that would suggest they are not credible. This is why we have due process. For baseball to be focusing on this and for us to be sitting here at Wrigley Field talking about this -- that's the problem."
Alex Rodriguez and Ryan Braun are among the players being interviewed as part of the inquiry. Braun is among several players who refused to answer questions about their dealings with Biogenesis, sources told ESPN's "Outside the Lines." Braun was interviewed last month and Rodriguez was scheduled to be interviewed Friday, sources confirmed.
Braun and Rodriguez have said they didn't do anything that merits discipline.
"We have a system in place that provides due process," Boras said. "Yet we have a dynamic in place that is operating outside the process of due process, where we are announcing things before we have a factual presentation.
"The joint drug agreement accounts for a hearing, a presentation of facts and we have announcements of suspensions and people involved without due process."
Boras said he didn't know where the leaks were originating.
"When we start doing this in American jurisprudence we have problem," he said. "This thing happening is not a part of the agreement. In these situations there is to be no notice and no names named, and yet we have this silent channeling of information. If the facts are applied through the system that is one thing, but until then, I don't think we should be talking specifics."
Michael Weiner, executive director of the players' union, said the drug agreement could be undermined by leaks to the media about whether players are cooperating with the investigation.
"Repeated leaks threaten to harm the integrity" of the drug agreement, Weiner said in a statement Thursday. He added that the leaks "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," Weiner said.
The union said it has no information about the source of the leaks or any indication that MLB is the source.
MLB has spent most of the year investigating about 20 players for their alleged links to Biogenesis, including Rodriguez and Braun, both former MVPs. The Miami New Times reported in January the clinic had distributed banned drugs to major leaguers.
The league had aimed to complete the player interviews by mid-month, but is not sure whether it will meet that schedule. Management then will have to decide on possible discipline, which is likely to be challenged in grievances before an arbitrator.
"It would be unfortunate if anyone prejudged the results of the investigation based on unsubstantiated leaks that are a clear violation of the JDA," Weiner said, referring to baseball's joint drug agreement.
Rodriguez has said he used performance-enhancing drugs while with Texas from 2001 to 2003, but has denied using them since.
Braun's 50-game suspension was overturned last year by an arbitrator, who ruled the Milwaukee star's urine sample was mishandled by the drug collector.
