The founder of a Miami anti-aging clinic has agreed to talk to Major League Baseball about players linked to performance-enhancing drugs, according to ESPN and the Associated Press.
The person declined to be identified because the investigation was still ongoing.
Information that Anthony Bosch provides MLB on players who came to the now-closed Biogenesis of America clinic could lead to suspensions.
Alex Rodriguez, Ryan Braun, Nelson Cruz and Melky Cabrera are among the 20 players whose names have been tied to the clinic.
MLB has sued Biogenesis of America and its operators, accusing them of scheming to provide banned PEDs to players in violation of their contracts.
Most have denied the Biogenesis link, although Rodriguez has admitted using performance-enhancing drugs earlier in his career and Colon and Cabrera each were suspended for 50 games last year for testing positive for elevated testosterone levels.
Braun failed a drug test in 2011, but his suspension was overturned by an arbitrator.
