Investigators for Major League Baseball have uncovered what they believe is evidence that a representative of Alex Rodriguez purchased medical records from a person connected to a South Florida anti-aging clinic that is suspected of providing performance-enhancing drugs to a number of major leaguers, according to two people briefed on the matter.

The New York Times reported online Thursday that Major League Baseball had purchased documents from a former employee at the clinic, which operated under the name Biogenesis of America and is now closed, in an effort to uncover evidence that would link the clinic to the distribution of performance-enhancing drugs. The article also stated that one major league player had also purchased clinic documents from a former clinic employee so that they could be destroyed. That player was not identified until Friday, when the two people said it was Rodriguez, the 37-year-old Yankees third baseman currently rehabilitating from off-season hip surgery.

A spokesman for Rodriguez flatly denied the allegation Friday.
