MIAMI – The man who released documents allegedly showing how the now-shuttered Biogenesis clinic provided performance-enhancing drugs to athletes says he is not disclosing more client names because of how messy he thinks Major League Baseball’s current investigation has gotten.

Porter Fischer, a former associate of Biogenesis head Tony Bosch, said Friday that he fears releasing more names and involving more leagues would further complicate his life.

“This whole fiasco with MLB has made me very, very wary about doing this with another agency,” Fischer said. “The way this whole thing has gone down with MLB makes me really, really apprehensive about starting another forest fire with somebody else. I mean, if you were me, would you go pick a fight with somebody else? I’d have NBA fans calling me names, I’d have a whole bunch of high-paid athletes calling me this-that, I’d have other goons at my door.”

Earlier this week, ESPN.com published a story saying Fischer alleged that NBA players, boxers, tennis players, college players and MMA fighters were among those who bought performance-enhancing drugs from Bosch, who operated the clinic.

Fischer said he wants law enforcement to take a look at what occurred at the clinic, and that his life has been threatened since he gave documents about the clinic and its customers to the Miami New Times, which in January detailed the alleged purchase of performance-enhancing drugs by Alex Rodriguez and others.

“I’d like to give it to the proper entities,” Fischer said. “But again, right now, I’m worried about walking out of my own house.”
