( CNN ) -- Major League Baseball has dropped its lawsuit against Anthony Bosch and the company the league claims provided performance-enhancing drugs to a number of players , including Yankees star Alex Rodriguez , a league spokesman said Tuesday . Mike Teevan , an MLB spokesman , said , `` We have dismissed our Biogenesis lawsuit . '' That suit was filed in March against the South Florida clinic and several men associated with it -- led by Bosch -- for allegedly flouting the league 's drug prevention program , the pro sports league said . The lawsuit 's dismissal was n't entirely unexpected . ESPN had reported that MLB might drop the suit against Bosch if he cooperated in its investigation . The investigation led to the suspension of 14 players for violating the league 's drug policy . Besides Rodriguez , suspended players included Milwaukee Brewers outfielder Ryan Braun , the 2011 National League MVP . Only one of the players challenged his suspension : Alex Rodriguez . After he called out Commissioner Bud Selig and others in his appeal of a 211-game ban , an arbitrator reduced it to 162 games and the postseason . The Yankees third baseman sued Major League Baseball , Selig and the players ' union to get the ban overturned , claiming the league engaged in vigilante justice during its investigation of Bosch and his Biogenesis anti-aging clinic . But earlier this month , Rodriguez abruptly dropped his suit and accepted his suspension . After a surge in home runs in the late 1980s and 1990s -- highlighted by Mark McGwire and Sammy Sosa racing to break Roger Maris ' single-season home run record in 1998 , followed three years later by Barry Bonds breaking the new record -- Major League Baseball was accused of not doing 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 , including ex-Red Sox standout Manny Ramirez , for 50 games in 2009 . Biogenesis became part of the story publicly in late January 2013 , when the Miami New Times reported that more than a dozen professional baseball players and other athletes had been named in records kept over several years by the clinic . Two months later , MLB filed its lawsuit against the clinic in Florida 's Miami-Dade County . Its 14-page complaint named Biogenesis , its predecessor company and six individuals -- among them program director 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 . According to Major League Baseball , the accused solicited players , supplied them with drugs and offered dosage recommendations to help them avoid testing 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 . CNN 's Adam Reiss contributed to this report .
