Calling MLB case 'a fiasco,' Fischer says he's wary of releasing more Biogenesis names

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 names because of how messy he thinks Major League Baseball's current investigation has gotten.

Porter Fischer tells The Associated Press that he considers baseball's investigation "a fiasco" and that it makes him "very, very wary" to approach other leagues.

Earlier this week, 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 his former associate Tony Bosch, who operated the clinic.

Fischer did not divulge names of any of those athletes in an interview Friday with the AP.
