Bosch backs Braun on Biogenesis explanation

Anthony Bosch, the former head of a Miami anti-aging clinic under investigation by Major League Baseball, on Monday denied knowledge of performance-enhancing drugs and declined to answer specific questions about all but one player with whom he has been connected: The Brewers' Ryan Braun.

In an interview with ESPN, Bosch corroborated what Braun said in a February statement, that Braun's lawyers merely consulted with Bosch during a successful appeal of a suspension during the 2011-12 offseason.

"I just answered a few questions from his legal team, not from Braun or any other ballplayer," Bosch told ESPN's Pedro Gomez.

The Miami New Times broke the Biogenesis story in January, reporting that Bosch had provided banned substances to a number of baseball players including the Yankees' Alex Rodriguez. Braun was not in the initial report, but several weeks later Yahoo Sports published what it said was an excerpt of Bosch's notes with Braun referenced three times, once with his initials next to "20-30K." After that report, Braun issued a statement saying he had "nothing to hide."

"During the course of preparing for my successful appeal last year, my attorneys, who were previously familiar with Tony Bosch, used him as a consultant," Braun said. "More specifically, he answered questions about T/E [testosterone to epitestosterone] ratio and possibilities of tampering with samples.

"There was a dispute over compensation for Bosch's work, which is why my lawyer and I are listed under 'moneys owed' and not on any other list. I have nothing to hide and have never had any other relationship with Bosch. I will fully cooperate with any inquiry into this matter."

It is not known whether Braun has spoken to MLB investigators
