Investigators for Major League Baseball believe they have uncovered evidence that a representative of Alex Rodriguez purchased medical records from a Miami anti-aging clinic believed to have supplied players with performance-enhancing substances.

The New York Times reported Friday that Rodriguez, the New York Yankees third baseman who is currently rehabilitating from off-season hip surgery, had purchased the documents from Biogenesis of America that link him to performance-enhancing drugs so that they could be destroyed, according to two people briefed on the matter.

On Thursday, the paper reported that Major League Baseball had purchased the documents from a former employee at the clinic in an attempt to try and link the clinic to the distribution of performance-enhancing drugs.

Rodriguez, as well as several other baseball players, were originally linked to the clinic in January, when the Miami New Times reported it had obtained medical records of players who had purchased banned substances -- namely human growth hormone -- from the clinic.

The 37-year-old Rodriguez has denied any ties to the clinic, and his spokesperson on Friday shot down the new allegations.
