A Pittsburgh law firm denied allegations that Rangers outfielder Nelson Cruz purchased performance-enhancing substances.

In its Tuesday edition, the weekly Miami New Times listed Cruz among a group of players who were customers at Biogenesis, an anti-aging clinic in the city that has since closed. The report said Cruz purchased $4,000 of testosterone-laden lozenges from clinic founder Anthony Bosch.

The firm of Farrell & Reisinger originally issued a statement Tuesday, but it did not come into circulation until Thursday. The firm's sports-law arm has been involved in baseball PED investigations since it advised slugger Sammy Sosa in advance of his disastrous appearance before a Congressional committee in 2005.

"We are aware of certain allegations and inferences …" the firm said. "To the extent these allegations and inferences refer to Nelson, they are denied."

Cruz has not spoken publicly or to the Rangers since the allegations were made.

New York Yankees third baseman Alex Rodriguez and Washington left-hander Gio Gonzalez have also denied the allegations that they purchased PEDs through Biogenesis. Oakland right-hander Bartolo Colon and San Diego catcher Yasmani Grandal, who have previous 50-game suspensions for violating the drug policy, have not responded to allegations against them.

According to the office of commissioner Bud Selig, Major League Baseball's Department of Investigations is "gathering and reviewing information" concerning the allegations.

The agreement between MLB and the Major League Baseball Players Association gives Selig the leeway to suspend players who have not failed a drug test. According to the agreement "possessions, selling, facilitating the sale of, distributing, or facilitating the distribution of any … prohibited substance" qualifies as a violation.
