In newly-released documents from a 2014 federal investigation, former Yankees third baseman Alex Rodriguez had told members of the U.S. Department of Justice and the Drug Enforcement Administration about fellow baseball players who had been purchasing performance-enhancing drugs (PEDs) from Biogenesis founder Anthony Bosch, including Manny Ramirez, Ryan Braun and one other All-Star player.
ESPN broke this story, but they declined to name the third All-Star player referenced by Rodriguez as he had never failed an official PED test.
Rodriguez, well-known by the nickname "A-Rod," delivered the testimony where he gave up his fellow PED users while meeting with federal law enforcement agents on January 29, 2014. This meeting came in the wake of his own positive test for PEDs, for which he earned a 211-game suspension from Major League Baseball (MLB), effectively booting him from the entirety of the 2014 season.
A-Rod had reportedly ratted on his fellow players in exchange for immunity from federal prosecution. The new documents unearthed by ESPN also indicate that he admitted to prosecutors that he had purchased PEDs for his personal use from Bosch after having previously denied doing so publicly.
Later, Ramirez would earn a 50-game suspension from the Dodgers in 2009 for PED use, and an additional 100 games in 2011 while with the Rays; however, he opted to retire instead of serving it.
Braun was suspended in 2013.
