(AP)—Major League Baseball is suing a now-shuttered South Florida clinic and its operators, accusing it of providing banned performance-enhancing drugs to players.

The filed Friday in Miami-Dade Circuit Court seeks unspecified damages from Coral Gables anti-aging clinic Biogenesis of America and its operator, Anthony Bosch. Several other Bosch associates are named in the lawsuit. A phone message left for a Bosch representative wasn't immediately returned.

MLB contends the clinic's operators solicited players to use banned substances knowing that violated their contracts. The lawsuit says baseball has suffered costs to investigate the claims, loss of revenue and injury to its reputation among fans.

Several prominent players have been implicated, including injured New York Yankees third baseman Alex Rodriquez. He and most of the others have denied ties to the clinic.
