(WNFL) - Major League Baseball is reportedly trying to obtain documents showing that a public relations firm leaked information which tied Ryan Braun to Bio-Genesis and its alleged performance-enhancing drug program. According to media reports, the documents indicated that Yankees' star Alex Rodriguez obtained records from Bio-Genesis so Major League Baseball could not get its hands on them. Now, the New York Daily News says baseball has filed a petition ordering the P-R firm of Sitrick-and-Company to comply with a subpoena as part of an arbitration hearing in which A-Rod seeks to overturn his 211-game suspension for his ties to Bio-Genesis. Braun, the Milwaukee Brewers' slugger, took a season-ending suspension in July for being part of the Bio-Genesis scandal. Baseball officials reportedly contend that either Rodriguez or the P-R firm leaked the Bio-Genesis information to Yahoo Sports, which first reported Braun's link to the now-defunct Miami clinic. The Daily News report said the players' union promised to have A-Rod share any documents related to Bio-Genesis -- but it could not produce the records that were given to Rodriguez' P-R firm.
