( CNN ) -- Major League Baseball on Friday sued a South Florida clinic Biogenesis of America and several men associated with it for flouting its drug prevention program by allegedly providing performance enhancing substances to players , the pro sports league said . According to reports and the MLB suit , filed in Florida 's Miami-Dade County , the clinic reportedly supplied banned performance enhancing substances to a number of current and former pro baseball players such as ex-Boston Red Sox Manny Ramirez . `` We believe we have a legitimate legal claim against the defendants , and we intend to pursue it vigorously , '' said Rob Manfred , Major League Baseball 's executive vice president of economics and legal affairs . A phone call placed Friday night by CNN to Bosch 's lawyer was not immediately returned . Previously , CNN has been unable to reach those involved in the clinic . And after the New Times story broke , a CNN crew went to the Coral Gables , Florida , address of the Biogenesis clinic and found its offices vacant . A-Rod denies performance-enhancing drugs reports . The 14-page complaint names Biogenesis , its predecessor and six individuals -- among them its program director Anthony Bosch , others at the company , someone who worked at a sports agency , a former University of Miami baseball player and a `` self-proclaimed chemist '' who supplied substances . The accused , according to Major League Baseball , solicited players , supplied them with drugs and offered dosage recommendations in order not to test positive for banned substances under the league 's program . `` ( The defendants ) knowingly and intentionally caused and/or induced ... players to breach their contractual obligations under MLB 's Joint Drug Prevention and Treatment Program , '' the complaint said . The complaint did not specify how much money it is seeking , beyond that it 's more than $ 15,000 . But it insists the league rightfully deserves to be paid given what BioGenesis and its affiliates have done to the sport . `` MLB has suffered damages , including the costs of ( the ) investigation , loss of goodwill , loss of revenue and profits and injury to its reputation , image , strategic advantage and fan relationships , '' the league alleges in its complaint . After a surge in home runs in the late 1980s and 1990s -- highlighted by Mark McGwire and Sammy Sosa racing to break Roger Maris 's single-season home run record in 1998 , followed three years later by Barry Bonds breaking the new record -- Major League Baseball came under a cloud amid allegations it had n't done enough to recognize , and combat , the use of performance enhancing substances . The league , in conjunction with its players ' union , in recent years has beefed up its drug testing programs and penalties . A number of top-level and minor league players have been suspended as a result , like Ramirez who was suspended 50 games in 2009 . Biogenesis became part of this story publicly in late January , when the Miami New Times reported that more than a dozen professional baseball players and other athletes were named in records kept over several years by the clinic . CNN was unable to independently obtain the documents the newspaper said it based its reporting on . And New Times reported earlier this month that it refused Major League Baseball 's request for records that contributed to its story . One of those players named by the publication is Alex Rodriguez , a 37-year-old New York Yankee who ranks fifth in home runs in major league history . Shortly after the New Times article came out , ESPN.com published a story quoting unidentified sources as describing how Bosch allegedly went to Rodriguez 's waterfront Florida mansion when summoned and injected the star player with performance-enhancing drugs , or PEDs . Rodriguez 's camp subsequently released a statement denying any connection to the Biogenesis ' clinic 's owner while disputing the aforementioned reports . `` The purported documents referenced in the story -- at least as they relate to Alex Rodriguez -- are not legitimate , '' the player 's public relations agent said .
